Does a DSCR Loan Replace My Current Mortgage, or Sit Behind It?
It depends on how you use it. A DSCR loan to buy a rental is a new loan on that property, and the mortgage on your home stays as it is. A DSCR refinance on a rental you own replaces that rental's mortgage. Some lenders also offer a DSCR second lien that sits behind the rental's first mortgage, so its rate stays in place.
Last updated November 3, 2026Buying a rental with a DSCR loan
A purchase loan is a new first mortgage on the property you're buying, and it's made on a rental you won't live in. The mortgage on the home you live in, and on any other property you own, doesn't change. You bring the down payment at closing. If you plan to use money borrowed against another property, ask the DSCR lender first whether it can count toward the down payment, because rules differ. See how much down payment a DSCR loan needs.
Refinancing a rental you already own
All four DSCR programs we read list a rate-and-term refinance and a cash-out refinance. Either one pays off the rental's current mortgage and replaces it with the new loan, at the new loan's rate and term:
- Rate-and-term changes the rate or term without taking money out, for example moving off short-term bridge debt onto a 30-year loan.
- Cash-out takes a larger loan and pays you the difference.
If the rental's current loan has a low rate, a refinance gives that rate up on the whole balance. See refinancing a DSCR loan.
Keeping the rental's first mortgage
A second lien keeps your first-mortgage rate in place and adds a separate loan behind it. Two of the four DSCR programs we read publish one on a rental: a closed-end second at one lender, and a fixed lump sum or a credit line at the other, both qualified on the property's rent. The other two don't list one, so ask before you apply.
What it costs you: a second payment, its own closing costs, and usually a higher rate on the new money. The CFPB notes that second mortgages often carry higher interest rates than first mortgages, because the second lender is paid after the first if the property is sold to repay them. Whether a second or a refinance comes out ahead depends on your current rate, how much you need and each lender's terms. See keeping a low first-mortgage rate with a second lien.
The home you live in isn't part of it
A DSCR loan is for an investment property. Borrowing against the home you live in, with a HELOC, a home equity loan or a cash-out refinance, is a different loan with its own approval, secured by your home. See whether you can use a DSCR loan on your primary home.
What depends on the lender
- Whether it offers a DSCR second lien at all
- Which refinance types it offers, and how long you need to have owned the property first
- How much of the property's value it will lend against
- Whether there's a prepayment penalty on the new loan, and what the current one charges if you pay it off
- Whether borrowed money can count toward a down payment
What to ask a lender
- Will this loan replace my current mortgage on the rental, or sit behind it?
- Do you offer a second lien on a rental, qualified on the rent?
- What does the current loan charge if I pay it off early?
- Can you show me the payment and costs for a refinance and for a second lien side by side?
