An interest-only DSCR loan lets you pay only the interest for the first several years of the loan. You get a lower payment and more monthly cash flow, and in exchange your balance doesn't go down during that stretch.
This page uses the structure shown on the Seale Rd listing and in the plan builder: a 30-year loan whose first 10 years are interest-only. Your loan documents set the real terms.
Neither structure wins in the abstract. They move the same dollars between your bank account and your loan balance, and the right choice depends on what you plan to do with the cash.
How the interest-only period works
A normal 30-year loan has one payment that covers interest plus a slice of principal. Early on most of it goes to interest, but the balance falls every month.
An interest-only loan splits the term in two. During the interest-only years, the payment is the balance times the rate, divided by 12. As the CFPB puts it, the amount you owe "does not go down with each payment." When the interest-only period ends, the loan switches to principal and interest for the years that remain.
The DSCR side works the same either way. The lender qualifies the loan on the property's rent against its payment, taxes, and insurance, not on your income, and a lower payment makes that ratio look better. For the ratio itself, see how to calculate DSCR.
The trade on a real listing
Take 2107 S Seale Rd in Phenix City, Alabama. It's listed at $230,000, and 20% down is $46,000, which leaves a $184,000 loan. The site estimates rent at $1,800 a month, taxes at $226, and insurance at $74. The site's interest-only payment of $997 uses a 6.5% rate, which it notes is not a Lineage quote. The listing also shows the 30-year amortizing payment at the same rate. The other amortizing figures are our own math. Every figure here is an estimate.
| Interest-only | Amortizing (30 years) | |
|---|---|---|
| Monthly loan payment | $997 (site estimate) | $1,163 (site estimate) |
| Taxes and insurance | $300 | $300 |
| Total monthly payment | $1,297 | About $1,463 |
| DSCR (rent divided by total payment) | 1.39 (site figure) | About 1.23 (our calculation) |
| Loan balance after 10 years | $184,000 | About $156,000 (our calculation) |
Interest-only keeps about $166 a month in your account, which adds up to roughly $19,900 over 10 years. The amortizing loan sends that money to the lender, and because the balance shrinks, it also pays less interest each year. After a decade it has cut about $28,000 off what you owe.
So interest-only leaves you with about $20,000 more cash, and amortizing leaves you with about $28,000 more equity. Plug in your own property with the DSCR loan calculator.

What you give up while principal paydown is paused
Principal paydown is one of the quieter ways a rental builds wealth. Every amortizing payment the rent covers shrinks your debt, and that equity is yours whether prices move or not. We go deeper on it in principal paydown.
An interest-only loan turns that off for the interest-only years. Appreciation can still grow your equity, but if values go flat, you owe exactly what you borrowed. That hurts most if you plan to sell or refinance during those years, because there's less room between the balance and the price.
The extra cash flow is money you chose to keep instead of paying toward the loan. It earns its place if you put it to work, say by building reserves or saving toward the next down payment. Our post on reinvesting rental cash flow walks through the options.
What happens when the interest-only period ends
In our illustration, the full $184,000 has to be repaid over the 20 years left on a 30-year loan. Squeezing the same balance into less time makes the payment higher than a 30-year amortizing payment would have been.
Here's our own illustrative math, not a lender figure. Inputs: a $184,000 balance, 20 years (240 monthly payments), and the rate held at 6.5%. The loan payment goes from $997 to about $1,372 in year 11, roughly $375 more a month. With the same $300 for taxes and insurance and the same $1,800 rent, DSCR would drop to about 1.08. Rent may well have risen by then, but you shouldn't count on it rising enough.
The CFPB lists the usual ways out: pay off the balance, refinance if you qualify, or start making the higher payments. It also warns against betting on a sale or a refinance, since values and rates can move against you. Your note says whether the rate can change after the interest-only period, so read that section before you sign.
Who it suits and who it doesn't
Interest-only tends to fit an investor who:
- Is buying more than one property and wants cash flow to help fund the next purchase.
- Wants a thicker DSCR cushion. A ratio of 1.39 leaves more room for a rent dip than 1.23. See what counts as a good DSCR ratio.
- Already has a plan for year 11, whether that's a refinance, a sale, or rent growth they've stress-tested.
It's a weaker fit if you:
- Plan to hold one property for decades and want the debt gone.
- Would spend the extra $166 a month rather than save or reinvest it.
- Couldn't handle a payment roughly $375 higher in year 11 if rents stall.
If you already own rentals on amortizing loans, adding one interest-only loan can make sense. The older loans keep paying down while the new one adds cash flow as you grow.
Figures above are illustrative estimates from one listing, not a loan offer or quote. Actual payments depend on your lender's terms, your rate, and the property. This is not investment advice.

Frequently asked questions
The risk is different. A lower payment helps if rent dips. But your balance doesn't fall, so you have less equity cushion if values drop, and the payment jumps when the interest-only period ends.
Many loans allow extra principal payments, which lowers the interest you're charged afterward. Check your note's prepayment terms first. Many DSCR loans carry a prepayment penalty, and on some it applies to partial paydowns too.
It can. DSCR compares rent to the full payment, so a lower payment produces a higher ratio. On Seale Rd it's 1.39 interest-only and about 1.23 amortizing. That depends on the lender. Some figure DSCR on the interest-only payment, some on a full principal-and-interest payment, and some don't offer interest-only. Ask which payment yours uses.
The plan builder models every rental with a 6.5% interest-only loan, so its cash flow figures run higher than an amortizing loan would show. Keep that in mind when you compare it with other projections.
