DSCR loans explained for Philadelphia row home investors

Every landlord who has been aggressive about depreciation eventually meets the same wall. The tax returns that keep your tax bill low also keep your qualifying income low, and a conventional underwriter reads the bottom line rather than the cash in your account.

A Debt Service Coverage Ratio loan sidesteps that entirely. It asks one question: does the property cover its own payment? Your returns stay in the drawer.

The ratio, precisely

DSCR is gross monthly rent divided by PITIA, which is principal, interest, taxes, insurance and any association dues. Not net operating income, not rent after management and vacancy. Gross rent over the full housing obligation.

Take a West Philadelphia row home at $245,000 with 20% down, so a $196,000 loan. At our sample DSCR rate of 7.375% on a 30-year fixed, principal and interest is $1,354. Philadelphia property tax at 1.398% of a $245,000 assessment is $285 a month. Landlord insurance runs roughly $115. PITIA is $1,754.

If the property rents at $1,950, the DSCR is 1.11. That clears our 1.10 threshold with almost nothing to spare. At $2,100 it is 1.20, which is comfortably inside standard pricing. At $1,800 it is 1.03, which prices 0.375% higher.

How interest-only changes the answer

The lever most investors miss is the payment structure. A ten-year interest-only period on that same $196,000 loan reduces the principal and interest component from $1,354 to $1,204. PITIA falls to $1,604.

At a $1,800 rent, the DSCR moves from 1.03 to 1.12. The property has not changed, the rent has not changed, and the file has moved from a 0.375% pricing adjustment into the standard tier. On a $196,000 loan that adjustment is worth roughly $47 a month.

The trade is real: you are not amortizing. For a buy-and-hold investor planning to refinance or sell inside ten years, that is often an acceptable trade. For someone intending to own the property outright in twenty years, it is not.

Interest-only is not a way to afford a property you cannot afford. It is a way to make a property that already works qualify at a better price.

Where the rent number comes from

If the unit is leased, we use the actual lease. If it is vacant or being acquired vacant, we use the appraiser's Form 1007 Single Family Comparable Rent Schedule, which sets market rent from comparable rentals in the area.

This is where Philadelphia gets interesting. Rents in Kingsessing, Cobbs Creek and Haddington vary block by block in ways an appraiser working from a wider radius will flatten. A weak Form 1007 can drop a 1.14 file to 0.98 and change the entire structure.

We review every rent schedule before it goes to underwriting, and we will submit a reconsideration with our own comparable rentals when the number looks wrong. On a tight file that review is worth more than any rate negotiation.

What DSCR actually costs

• Rate: roughly 1.000% to 1.500% above owner-occupied conventional. Our sample 30-year DSCR rate is 7.375% against 6.125% conventional.
• Down payment: 20% on a purchase, 25% on a cash-out refinance. There is no 3% down version of this product.
• Prepayment penalty: a 5/4/3/2/1 step-down is standard. Buying it out costs points at closing.
• Reserves: six months of PITIA verified, and more on a no-ratio file below 1.00.

Run it before you offer, not after

The most expensive mistake in this product is writing an offer and then discovering the ratio does not work. By then you have an inspection paid for, an appraisal ordered and a deposit at risk.

The calculation takes two minutes. Estimated rent, purchase price, down payment, taxes from the Philadelphia OPA site, an insurance quote. Our DSCR calculator does it live, and if the answer lands between 1.00 and 1.10 there are three levers worth pulling: more down, interest-only, or a different property.

Investors who bring us a ratio already run close faster and negotiate better, because they know at the moment of offer what the financing will actually cost.
