DSCR HELOC: Tapping Rental Equity Without Refinancing Your First Mortgage

Thousands of investors are sitting on the same problem: a rental with a lot of equity and a first mortgage at a rate they'll never see again. A cash-out refinance would release the equity and destroy the rate. What they want is a second lien. What they find is that most banks don't offer HELOCs on investment properties, and the ones that do want two years of tax returns.

It's a second-lien loan on a rental property, underwritten the way a DSCR loan is: on the property's cash flow rather than the borrower's income. The product comes in two forms. A true HELOC is a revolving line with a draw period, interest-only payments during the draw, and a variable rate. A DSCR second mortgage — more widely available — is a closed-end loan with a fixed rate, funded in a lump sum. Lenders and brokers often use the term DSCR HELOC for both.

The lender takes the gross monthly rent and divides it by the total payment on the property: the existing first mortgage's principal and interest, taxes, insurance, HOA, and the new second lien's payment. The combined figure generally needs to reach 1.0 or higher. Because the first mortgage on these properties tends to have a low payment, there's often more room than investors expect. Background on the ratio is in what is a good DSCR ratio.

• Combined loan-to-value: commonly capped around 70% to 75% of the property's value across both liens.
• Credit score: often 680 to 700 or higher — tighter than first-lien DSCR programs.
• Rates: higher than a first-lien DSCR loan, reflecting the second-lien position.
• Loan size: minimums and maximums vary; very small lines are hard to place.
• Property: one-to-four-unit rentals with a lease in place or market rent supported by an appraisal.

These are general ranges, not an offer — this is a specialty product and terms differ substantially from lender to lender.

Do the blended-rate math. Suppose you owe $200,000 at 3.5% and want $100,000 out. A cash-out refinance replaces the whole thing with $300,000 at today's investor rates. A second lien leaves the $200,000 alone and prices only the new $100,000 — at a higher rate than the refinance, but on a third of the money. In most cases where the first mortgage is more than two points under the market, the second lien wins on total monthly cost. When the first mortgage is already near market, or the balance is small, a DSCR cash-out refinance is simpler and usually cheaper. The refinance path is detailed in DSCR refinance.

• A conventional HELOC on an investment property, if your tax returns support it and you can find a bank that offers one.
• A bank statement HELOC on your primary residence, if you're self-employed.
• A cross-collateral loan, which pledges the equity toward a new purchase without a separate second.

Down payments on the next rental are the most common use — it's one of the strategies in DSCR loan with no down payment. Renovations that raise rent, paying off a high-rate hard money loan, and building a reserve line for a growing portfolio are the others.

Send me the property's value, the first mortgage balance and rate, and the rent. I'll run the second lien against a cash-out refinance side by side so you can see which costs less. Check the combined ratio yourself with the DSCR calculator. Availability varies by state, lender, and property type.
