Is a DSCR loan really a no-doc loan?

No. It is a no-income-doc loan, which is a much narrower claim. There is still an appraisal, still a title search, still a credit pull with a minimum score, and still a reserves requirement you document with bank statements. What you do not provide is tax returns, W-2s or a debt-to-income calculation. The underwriting did not disappear; it moved from you to the property.

Why is the DSCR rate higher if the property covers the payment?

Because the lender gave up its best evidence. A conventional lender knows what you earn, what you owe and how long you have earned it, and prices the loan knowing you can cover a vacancy out of pocket. A DSCR lender is looking at a rent estimate and a credit score. That is less information, and less information costs more. The gap is commonly one to two percentage points, though it moves with the market and with your credit and leverage.

Which one should I use?

If you qualify conventionally and are under the financed-property cap, conventional is nearly always the cheaper money — lower rate, no prepayment penalty. DSCR earns its cost when conventional is closed to you: you are self-employed and your returns show little income, you are past the property cap, you want to hold in an LLC, or you need to close faster than a full-doc file allows. That is a general pattern, not advice on your file; a broker can price both against your actual numbers.

How is the DSCR ratio itself calculated?

Two different ways, both called DSCR. Most investor lenders use gross monthly rent divided by PITIA — principal, interest, taxes, insurance and association dues. The commercial convention subtracts operating expenses to get net operating income, then divides by principal and interest only. The second number is almost always lower. Ask which one your lender underwrites to before assuming you qualify.

Does the prepayment penalty apply if I sell?

Usually yes. That is the part investors most often miss, because a penalty framed as discouraging a refinance also catches a sale. Structures vary — some are stepped, some are a flat percentage of the balance, some waive on sale but not on refinance. It is negotiable at pricing: many lenders will shorten or remove the penalty in exchange for a higher rate. Read the term sheet for how it behaves on a sale specifically.

DSCR loan vs conventional

The difference is not really the rate. A conventional loan qualifies you — your income, your debts, how many properties you already finance. A DSCR loan qualifies the property — whether the rent covers the payment. Everything else about the two products follows from that one change, including why the second costs more.

Side by side

	Conventional	DSCR
What is underwritten	You — income, employment, debts	The property — rent against the payment
Income documentation	Tax returns, W-2s or full self-employed package	None. A lease or market rent survey instead
Debt-to-income ratio	Calculated, and capped — commonly around 45–50%	Not calculated at all
Properties you may already own	Capped. Fannie Mae stops at ten financed properties	Usually uncapped
Vesting	Personal name	LLC permitted, and usually preferred
Rate	Lower — the cheapest money available on a rental	Higher, commonly by one to two percentage points
Prepayment penalty	None	Usual. Often three to five years, stepping down
Reserves	Required, and counted across every property you own	Required — typically several months of payments

What the rate comparison leaves out

Comparisons of these two products almost always stop at the rate, and the rate is the part that behaves predictably. Two things move the real cost more.

The first is the prepayment penalty. Conventional investor loans do not carry one; most DSCR loans do, commonly for three to five years and often stepping down each year. It is frequently written to catch a sale as well as a refinance, which matters if the plan was ever to season the property and exit. It is also the most negotiable term on the sheet — many lenders will shorten or drop it for a higher rate, which is a trade worth pricing rather than accepting by default.

The second is which DSCR formula the lender uses. Gross rent over PITIA and net operating income over debt service are both called DSCR, and the same file can pass on one and fail on the other. That is not a rounding difference; it decides whether the loan exists.
