Mortgage Glossary: Plain-English Term Definitions

Application & Pre-Approval Terms

These terms come up during application, pre-approval, and the early stages of file preparation.

1. 1003 (Uniform Residential Loan Application). The standard mortgage application form used across the industry. Form 1003 (Fannie Mae) and Form 65 (Freddie Mac) are functionally equivalent. The form has been redesigned several times; the current version is the URLA (Uniform Residential Loan Application).
2. AUS (Automated Underwriting System). Software that processes a mortgage application and produces an underwriting recommendation. Fannie Mae's system is Desktop Underwriter (DU); Freddie Mac's is Loan Product Advisor (LPA). FHA, VA, and USDA loans also run through these systems.
3. Borrower. The individual(s) on the loan application and the deed (or just the loan, in some non-occupant-co-borrower scenarios). The borrower is responsible for repayment.
4. Co-Borrower. A second individual on the loan application — usually a spouse or family member — whose income, credit, and assets are jointly considered. A non-occupant co-borrower is allowed on certain programs (FHA, conforming conventional, with restrictions).
5. Credit Score (FICO). A numerical assessment of credit risk from FICO, the dominant scoring model used in mortgage underwriting. Scores range from 300 to 850; mortgage lenders use the middle of three FICO scores (one from each major bureau). Different FICO model versions are used for different purposes — mortgage uses FICO 2, FICO 4, and FICO 5 (one per bureau), which differ slightly from the FICO 8 score most commonly shown to consumers.
6. DTI (Debt-to-Income Ratio). The borrower's monthly debt obligations (including the proposed mortgage payment) divided by gross monthly income. Most loan programs cap DTI at 43-50%; specific caps vary by program and by AUS recommendation.
7. Front-End DTI. The housing payment alone (PITIA) divided by gross income. Some programs evaluate front-end and back-end (total) DTI separately.
8. Gift Funds. Money provided to the borrower by a family member, employer, charity, or government program to use for down payment or closing costs. Gift funds must be documented with a gift letter showing the donor, amount, source, and a statement that no repayment is expected.
9. Hard Inquiry / Hard Pull. A credit check made for the purpose of extending credit, recorded on the credit report and visible to other lenders. Hard inquiries can reduce FICO score by 1-5 points temporarily.
10. Pre-Approval. A verified, underwritten loan-approval letter based on documented income, assets, credit, and employment. Stronger than pre-qualification. See the Pre-Approval Guide for details.
11. Pre-Qualification. An estimated loan amount based on borrower-stated information without verification. Weaker than pre-approval — typically not strong enough for offers in competitive markets.
12. Soft Inquiry / Soft Pull. A credit check made for non-credit-extending purposes (such as a pre-qualification or the borrower checking their own credit). Not visible to other lenders and not used in FICO scoring.
13. SSN (Social Security Number). Required for credit pull and identity verification on all standard mortgage applications. Non-citizens use ITIN (Individual Taxpayer Identification Number) or passport identification on specific programs (ITIN loans, foreign-national programs).
14. Tri-Merge Credit Report. A consolidated credit report combining data from all three major bureaus (Equifax, Experian, TransUnion). Mortgage underwriting uses a tri-merge; consumer-facing credit reports often use only one bureau.
15. URLA (Uniform Residential Loan Application). The redesigned standardized loan application form (also Form 1003). The URLA captures borrower demographics, income, assets, debts, and the loan request.

Loan Program Terms

These terms identify the type of loan program and its underwriting framework.

1. ARM (Adjustable-Rate Mortgage). A mortgage with an interest rate that can change periodically based on a benchmark index (SOFR, Treasury). Common structures: 5/6 ARM (fixed for 5 years, then adjusts every 6 months), 7/6 ARM, 10/6 ARM.
2. Bank-Statement Loan. A non-QM (non-qualified mortgage) program that qualifies self-employed borrowers based on 12-24 months of business or personal bank statement deposits, rather than tax returns. Useful for self-employed borrowers whose tax returns understate true income because of legitimate write-offs.
3. Conforming Loan. A conventional loan that conforms to Fannie Mae or Freddie Mac size limits and underwriting guidelines. The 2026 conforming loan limit is $806,500 in most counties, higher in designated high-cost counties.
4. Conventional Loan. A mortgage loan not insured or guaranteed by a federal government agency. Includes conforming loans (eligible for Fannie/Freddie purchase) and non-conforming loans (jumbo, non-QM).
5. DSCR Loan. Debt Service Coverage Ratio loan — qualifies investor borrowers based on the rental income the property produces relative to its monthly mortgage payment, not personal income. See the DSCR Loan Guide.
6. FHA Loan. A mortgage insured by the Federal Housing Administration. Allows lower down payments (3.5%) and lower credit scores (580 standard, 500 with 10% down) than conventional, in exchange for FHA mortgage insurance premiums.
7. Fixed-Rate Mortgage. A mortgage with an interest rate that remains the same for the entire loan term. Standard terms are 15, 20, and 30 years. Predictable monthly payment.
8. HELOC (Home Equity Line of Credit). A revolving line of credit secured by the borrower's home, with a variable rate tied to the prime rate. See the HELOC Guide.
9. Home Equity Loan. A fixed-rate lump-sum second mortgage, repaid over a fixed term with predictable monthly payments. Different from HELOC.
10. Jumbo Loan. A loan above the conforming loan limit. Pricing, qualification, and reserve requirements are typically tighter than conforming. See the Jumbo Loan Guide.
11. Non-QM (Non-Qualified Mortgage). A category of loans that does not meet the Consumer Financial Protection Bureau's "Qualified Mortgage" definition under the ability-to-repay rule. Includes bank-statement, DSCR, asset-depletion, foreign-national, and other alternative-doc programs.
12. Portfolio Loan. A loan that the lender keeps in their own portfolio rather than selling to investors. Portfolio loans can have more flexible underwriting because the lender bears the credit risk directly.
13. Purchase Money Loan. A mortgage used to purchase the property securing the loan, as opposed to a refinance.
14. Refinance. Replacing an existing mortgage with a new mortgage. Rate-and-term refinance replaces the loan with similar terms (no cash out). Cash-out refinance pays off the existing loan and provides additional cash to the borrower.
15. USDA Loan. A mortgage guaranteed by the U.S. Department of Agriculture for rural and suburban areas, with zero down payment for income-eligible borrowers in designated USDA-eligible areas. See the USDA Loan Guide.
16. VA Loan. A mortgage guaranteed by the U.S. Department of Veterans Affairs, available to eligible veterans, active-duty servicemembers, and certain surviving spouses, with no down payment and no monthly mortgage insurance. See the VA Loan Guide.

Underwriting & Pricing Terms

These terms come up during underwriting, rate-shopping, and loan pricing.

1. APR (Annual Percentage Rate). The total annualized cost of the loan, including the interest rate plus most lender fees, expressed as a single percentage. APR is generally higher than the note rate and is designed for apples-to-apples comparison across lenders.
2. Buydown. Pre-paying interest at closing in exchange for a lower interest rate for some portion of the loan. Temporary buydowns (2-1, 1-0) reduce the rate for the first 1-3 years; permanent buydowns reduce the rate for the entire loan.
3. Conditions. Additional documentation or actions the underwriter requires before the loan can close. Conditions typically include items like updated paystubs, gift letters, explanation letters, evidence of paid-off debts, or property-specific items.
4. Conditional Approval. The underwriter's approval pending clearance of specific conditions. Most loans are conditionally approved before they are clear-to-close.
5. Discount Points. Pre-paid interest at closing — each point equals 1% of the loan amount and typically reduces the interest rate by 0.125-0.25%. Buying points makes economic sense when the borrower intends to keep the loan long enough to recoup the upfront cost.
6. Float. Choosing not to lock the interest rate at the time of application, betting that rates will improve before closing. Floating is risky because rates can also move against you.
7. Lender Credit. The opposite of discount points — the lender pays some of the closing costs in exchange for the borrower accepting a slightly higher interest rate. Lender credit makes sense when the borrower wants to minimize cash to close.
8. Lock (Rate Lock). A binding commitment by the lender to provide a specific interest rate for a specific period (typically 30, 45, 60, or 90 days). Once locked, the borrower's rate is protected against market moves through closing.
9. LTV (Loan-to-Value Ratio). The loan amount divided by the property's appraised value. Lower LTV is better for the lender; higher LTV typically means higher pricing or required mortgage insurance.
10. Note Rate (Interest Rate). The actual interest rate on the note — the percentage used to calculate the monthly interest payment. Different from APR.
11. PITIA (Principal, Interest, Taxes, Insurance, Association dues). The full monthly housing payment used for DTI calculation. Includes principal, interest, property taxes, homeowners insurance, HOA dues if applicable, and mortgage insurance if applicable.
12. PITI. Same as PITIA but without association dues — used when no HOA is present.
13. QM (Qualified Mortgage). A mortgage that meets the Consumer Financial Protection Bureau's ability-to-repay standards. QM status gives the lender legal protection from ability-to-repay claims. Loans that fall outside QM are called non-QM.
14. Reserves. Liquid assets the borrower must have after closing — typically expressed in months of PITIA payments. Conventional loans on primary residence may require 0-2 months reserves; jumbo and investment-property loans require 6-24 months.
15. TBD Pre-Approval (Property To Be Determined). A fully underwritten pre-approval where the file has cleared all conditions except property-specific items. Considered the strongest type of pre-approval.
16. Underwriter. The person at the lender (or AUS engine) who makes the credit decision on the loan. The underwriter reviews documents, applies guidelines, adds conditions, and ultimately clears the loan for closing.

Closing Terms

These terms come up during the closing process — typically the final 7-14 days before funding.

1. Cash to Close. The total amount of money the borrower must bring to closing — down payment plus closing costs, minus any earnest money already paid, lender credits, and seller concessions. Shown explicitly on the Loan Estimate and Closing Disclosure.
2. Closing Costs. All fees and charges associated with the loan and the property transfer at closing. Includes lender fees (origination, underwriting), third-party fees (appraisal, title insurance, recording fees, transfer taxes), prepaid items (interest, insurance, escrows), and miscellaneous costs.
3. Closing Disclosure (CD). The federally required disclosure provided to the borrower at least three business days before closing, showing final loan terms and closing costs. Must be substantially consistent with the Loan Estimate.
4. Clear to Close (CTC). The underwriter's final approval — all conditions cleared, file ready for closing. CTC is the moment the closing department schedules the actual closing.
5. Deed. The legal document transferring ownership of real property from seller to buyer. The mortgage (or deed of trust, in deed-of-trust states) is a separate document that creates the security interest.
6. Deed of Trust. Used in deed-of-trust states (most non-judicial-foreclosure states, including Texas and Tennessee) as the mortgage instrument. Functionally similar to a mortgage but with three parties (borrower, lender, trustee) rather than two.
7. Earnest Money. A deposit paid by the buyer at the time of accepting the offer, held in escrow until closing as evidence of good faith. Typically 1-3% of purchase price. Applied to cash-to-close at closing.
8. Escrow. An account held by a third party (the escrow company, title company, or lender) that holds funds or documents until specified conditions are met. Closing escrow holds money during the transaction. Mortgage escrow account (a separate concept) holds property tax and insurance prepayments and pays those bills on behalf of the borrower.
9. Funding. The moment the lender wires loan proceeds to the closing agent. Funding can be same-day as signing (most states) or a day later (escrow states like California).
10. Loan Estimate (LE). The federally required disclosure provided to the borrower within three business days of receiving a complete application, showing the loan terms and closing costs. Standardized format for cross-lender comparison.
11. Mortgage. The legal document creating the lender's security interest in the property. Used in mortgage states (most judicial-foreclosure states, including Florida and South Carolina).
12. Origination Fee. A fee charged by the lender for originating the loan. Disclosed on the Loan Estimate. Some lenders charge a flat fee; some charge a percentage of loan amount.
13. Owner's Title Insurance. Title insurance protecting the buyer against title defects. Separate from lender's title insurance (which protects the lender). Owner's title is optional but strongly recommended.
14. Recording. The act of filing the deed and mortgage with the county recorder, which creates the public record of ownership and the lien. Recording fees and transfer taxes are typically part of closing costs.
15. Settlement. The closing event — the meeting (in-person or remote) where the buyer signs all loan documents and the property title transfers. "Settlement" is the standard term in some Eastern U.S. states; "closing" is more common elsewhere.
16. Title. Legal ownership of real property. Title insurance protects against defects in the title chain that could affect ownership.
17. TRID (TILA-RESPA Integrated Disclosure). The federal regulation that established the Loan Estimate and Closing Disclosure forms and the three-business-day pre-closing window. TRID has been in effect since October 2015.

Insurance & Tax Terms

These terms relate to ongoing costs of property ownership beyond principal and interest.

1. Escrow Account. An account maintained by the lender (or loan servicer) that collects monthly payments toward property taxes and homeowners insurance, then pays those bills when due. Most loans require an escrow account; some allow escrow waiver at LTV below 80% (or 90%, depending on lender) for a small rate premium.
2. FEMA Flood Zone. The Federal Emergency Management Agency designates flood zones based on flood risk. Properties in Special Flood Hazard Areas (Zones A and V) require flood insurance for federally backed mortgages. Other zones (B, C, X) are not required to carry flood insurance but the borrower may still choose to.
3. Hazard Insurance / Homeowners Insurance. Insurance protecting the property against fire, theft, wind damage, and other hazards. Required by the lender on every mortgage. Premium is paid annually, typically through the escrow account.
4. Homestead Exemption. A property-tax exemption in many states that reduces taxable value for primary residences. Florida has one of the strongest homestead exemptions; Texas's homestead protection extends beyond tax exemption to creditor-protection rules.
5. Lender-Paid Mortgage Insurance (LPMI). Mortgage insurance where the lender pays the premium upfront in exchange for a higher interest rate. The borrower does not see a separate monthly MI payment, but pays for it through the rate.
6. MIP (Mortgage Insurance Premium). The mortgage insurance specifically on FHA loans, consisting of an upfront MIP (1.75% of loan amount, typically financed) and an annual MIP paid monthly (typically 0.55% of loan amount annually, varies by LTV and term). See the PMI/MIP Guide.
7. Mortgage Insurance. Insurance that protects the lender (not the borrower) in case of borrower default. Required on most loans with LTV above 80% (conventional, FHA, USDA). VA loans use a funding fee rather than mortgage insurance.
8. NFIP (National Flood Insurance Program). The federal flood insurance program administered by FEMA. Provides flood insurance for properties in NFIP-participating communities. Private flood insurance is also available and increasingly competitive.
9. PMI (Private Mortgage Insurance). Mortgage insurance specifically on conventional loans with LTV above 80%. PMI is paid monthly and can be canceled once LTV reaches 80% based on original purchase price (and automatically terminates at 78% under the Homeowners Protection Act).
10. Property Taxes. Taxes levied by county and municipal governments based on assessed property value. Property tax rates and assessment methods vary materially by state and county.
11. Save Our Homes Cap. A Florida-specific property tax cap that limits annual increases in homestead assessed value to 3% (or the CPI change, whichever is lower). Significant long-term tax benefit for Florida homestead homeowners.
12. USDA Guarantee Fee. USDA's analog to mortgage insurance — an upfront guarantee fee (1.0%) plus an annual fee paid monthly (0.35%). USDA-insured loans use this fee structure rather than traditional mortgage insurance.
13. VA Funding Fee. A one-time fee charged on VA loans to support the VA loan program. Ranges from 1.25% to 3.3% of loan amount based on down payment, first-use vs subsequent-use, and disability status. Veterans with service-connected disabilities are exempt.
14. Windstorm / Hurricane Insurance. Coverage for wind damage from hurricanes and severe storms. Often a separate policy or endorsement in coastal states (especially Florida, the Carolinas, and Gulf Coast). Required by the lender in designated wind zones.

Default & Foreclosure Terms

These terms relate to default, foreclosure, and distressed-property scenarios. See the Foreclosure Buying Guide for context.

1. Acceleration Clause. A provision in the mortgage that allows the lender to demand immediate payment of the full loan balance upon borrower default. Foreclosure proceeds from acceleration.
2. Cure / Reinstatement. The borrower's right to bring the loan current by paying all past-due amounts (typically before foreclosure sale) and have the loan reinstated. The right to cure exists in nearly all states with various deadlines.
3. Deed in Lieu of Foreclosure. A voluntary transfer of the property from borrower to lender in exchange for release from the mortgage debt. Avoids the foreclosure process. Less damaging to credit than full foreclosure but more damaging than a successful short sale.
4. Default. Failure to meet the obligations of the mortgage — most commonly missed payments. Technical default can also include failure to maintain insurance, failure to pay property taxes, or breach of other loan covenants.
5. Deficiency Judgment. A court judgment requiring the borrower to pay the difference between the loan balance and the foreclosure-sale proceeds. Some states (Texas, in many situations) prohibit or limit deficiency judgments; others (Florida, in many situations) allow them. Highly state-specific.
6. Forbearance. A temporary agreement between borrower and lender to pause or reduce payments for a set period, typically because of a temporary hardship. Different from forgiveness — the missed payments must still be repaid eventually.
7. Foreclosure. The legal process by which the lender takes back the property after borrower default. Varies by state — judicial (court-required) or non-judicial (under deed of trust authority).
8. Foreclosure Auction / Trustee's Sale / Sheriff's Sale. The public sale at which the property is sold after foreclosure. Required to pay cash same-day or within hours; not financeable with traditional mortgages.
9. Judicial Foreclosure. Foreclosure conducted through the courts, required in some states (including Florida and South Carolina). Typically slower than non-judicial foreclosure.
10. Notice of Default (NOD). The formal notice that the borrower is in default and the foreclosure process is starting. Recorded publicly and triggers a series of statutory deadlines.
11. Non-Judicial Foreclosure. Foreclosure conducted under deed-of-trust authority without court action. Available in most states (including Texas and Tennessee). Typically faster than judicial foreclosure.
12. Pre-Foreclosure. The period after notice of default but before the foreclosure sale. The property may be eligible for short sale during this period.
13. Public Trustee. The county officer in Colorado who administers foreclosures. A unique Colorado feature — the Public Trustee role is between judicial and non-judicial structures.
14. Redemption. The borrower's right to reclaim the property after foreclosure sale by paying the full debt. Some states preserve redemption for a period after sale; many do not.
15. REO (Real Estate Owned). Property the lender has taken back after an unsuccessful foreclosure auction. REO is now owned by the lender and is listed for sale through standard real-estate-listing mechanics.
16. Short Sale. Sale of a property for less than the mortgage balance, with the lender's explicit approval to release the lien for less than full payoff.

State-Specific Notes

Mortgage terminology is mostly federally standardized, but a few important terms have state-specific definitions:

Florida

Florida-specific terms worth knowing: Homestead Exemption — a property-tax exemption that reduces taxable value for primary residences (up to $50,000 in base exemption, with additional exemptions for seniors, veterans, and disabilities); Save Our Homes Cap — limits annual increases in homestead assessed value to 3% (or CPI); Surfside Reserve Requirements — post-2021 Florida condo law requiring structural reserves and inspections that affect condo financing eligibility; Florida Bond, Hometown Heroes, Salute Our Soldiers, Florida Assist — state-administered borrower-assistance programs. Florida is a judicial-foreclosure state.

Texas

Texas-specific terms: Section 50(a)(6) — the Texas Constitution provisions governing home equity lending on homestead property, with unique rules including 80% CLTV cap, 12-day cooling-off period, and one-equity-loan-at-a-time restriction; One-Action Rule — in some Texas foreclosure scenarios, the lender must choose between foreclosing and suing on the note; Homestead — Texas homestead is constitutionally protected against most general-creditor claims (mortgage liens excepted), with both rural and urban homestead categories. Texas is primarily a non-judicial-foreclosure state with first-Tuesday-of-the-month trustee sales.

Tennessee

Tennessee-specific terms: Trustee's Sale — the foreclosure sale conducted by the trustee under deed-of-trust authority (Tennessee is non-judicial); Right of Redemption — generally not preserved after foreclosure sale in Tennessee, except in specific circumstances; Mortgage Tax — a small state tax on recorded mortgages applies in Tennessee. Tennessee has no state income tax.

South Carolina

South Carolina-specific terms: Master in Equity — the county-level court official who typically oversees judicial foreclosures (South Carolina is a judicial-foreclosure state); 4% vs 6% Assessment Ratio — owner-occupied primary residences are assessed at 4% of fair market value for property-tax purposes; non-owner-occupied (second homes, investment property) are assessed at 6%; Equity of Redemption — preserved up to the foreclosure sale.

Colorado

Colorado-specific terms: Public Trustee — the county-appointed official who administers foreclosures in Colorado, under the Public Trustee system (a hybrid between judicial and non-judicial); Rule 120 Hearing — the limited court hearing that confirms a foreclosure can proceed in Colorado, providing court oversight of the Public Trustee process. Colorado has no significant Gallagher-era property tax assessment-ratio complications anymore (Gallagher was repealed in 2020).
