First lien vs. second lien
How lien priority works, why it matters for home equity borrowing, and how it affects refinancing.
A lien is a legal claim against your property securing a debt. The first lien has priority and is paid first if the property is sold or foreclosed; a second lien sits behind it and is paid only after the first is satisfied.
What lien priority means
When you borrow against your home, the lender records a lien — a legal claim on the property that secures the loan. If there is more than one loan against the home, the liens have an order of priority, generally based on when they were recorded. The first lien (usually your primary mortgage) is in first position; a second lien is subordinate to it.
Priority matters most in a sale or foreclosure. Proceeds pay off the first lien before anything goes to the second. Because the second-lien holder takes on more risk of not being fully repaid, second-lien financing is underwritten with that risk in mind.
Where second liens come from
The most common second liens are home equity loans and home equity lines of credit (HELOCs). These let you borrow against the equity you have built while keeping your existing first mortgage in place — useful when your primary loan has terms you want to preserve. A piggyback second mortgage taken at purchase is another example.
Because the second lien is behind the first, it depends on there being enough equity to support both. Your combined loan-to-value — all loans against the home relative to its value — is a key figure lenders look at.
How liens affect refinancing
If you have a second lien and want to refinance your first mortgage, the second-lien holder generally must agree to remain in second position behind the new first mortgage. This is called subordination. Without it, paying off and replacing the first mortgage would move the second lien into first position, which the new first-lien lender will not accept.
Subordination is a routine but real step, and it is one reason it helps to plan a refinance with all liens in view. We can help you understand how existing liens affect your options.
Frequently asked questions
What is the difference between a first and second lien?
The first lien has priority and is paid first in a sale or foreclosure; the second lien is subordinate and paid only after the first is fully satisfied. The order is generally based on recording date.
Is a HELOC a first or second lien?
Usually a second lien, because it is taken while your primary mortgage stays in first position. A HELOC can be a first lien if there is no other mortgage on the home.
Why do second liens carry more risk for lenders?
Because in a sale or foreclosure the first lien is paid before the second. If proceeds are not enough to cover both, the second-lien holder may not be fully repaid, so it is underwritten with that risk in mind.
What is lien subordination in a refinance?
It is when a second-lien holder agrees to stay behind the new first mortgage after you refinance. Without subordination, the second lien would jump to first position, which a new first lender will not allow.
What is combined loan-to-value?
It is the total of all loans secured by your home relative to the home’s value. Lenders use it to evaluate second-lien and cash-out requests, since it reflects total borrowing against the property.
