DSCR Loan Programs
DSCR is a category, not a single product. The structure you choose changes the ratio, the payment and the exit.

The Main Structures
| Structure | How it works | Best for |
|---|---|---|
| 30-year fixed | Fully amortising, rate fixed for the term | Long-term buy-and-hold |
| 40-year fixed | Lower payment, longer amortisation | Raising a thin DSCR ratio |
| Interest-only | IO for 5–10 years, then amortises | Maximising cash flow during a hold |
| 5/1 or 7/1 ARM | Fixed then adjusting | Planned sale or refinance inside the fixed period |
| Short-term rental | Underwrites Airbnb/VRBO revenue | Vacation and STR properties |
| Portfolio / blanket | Multiple properties, one loan | Investors with several doors |
Structure Changes the Ratio
This is the practical reason structure matters. A 40-year term or an interest-only period lowers the monthly payment, and because DSCR is rent divided by payment, a lower payment raises the ratio directly.
A property that fails at 1.05 on a 30-year fixed may clear 1.25 on a 40-year interest-only structure — same property, same rent, different loan. That can be the difference between approval and decline, though it comes at the cost of building equity far more slowly.
Interest-only is a timing decision
An interest-only DSCR loan pays down no principal during the IO period, and the payment jumps when it recasts. It suits investors with a defined exit inside the IO window — a sale, a refinance, or a repositioning. It suits a permanent hold much less well.
Short-Term Rental Programs
A growing number of lenders underwrite short-term rental revenue rather than a long-term lease, using either a 12-month platform history or an AirDNA-style market projection. STR revenue frequently produces a stronger ratio than a long-term lease on the same property.
The constraint in California is local regulation, which varies enormously between cities. Confirm the property can legally operate as a short-term rental before relying on that income. See short-term rental loans.
Portfolio and Blanket Loans
Investors with several properties can consolidate into a single blanket loan covering multiple doors, with one payment and one set of closing costs. Release clauses allow individual properties to be sold without repaying the whole facility.
The trade is flexibility: a blanket loan ties properties together, and refinancing or selling one becomes more complex. See portfolio loans.
Choosing Between Them
Start from the exit. A ten-year hold argues for 30-year fixed. A three-year reposition argues for an ARM or interest-only with a short prepayment penalty. A thin ratio argues for 40-year or interest-only. Model each with the DSCR calculator before committing.

Frequently Asked Questions
What DSCR loan structures are available?
The main options are 30-year fixed, 40-year fixed, interest-only for five to ten years, 5/1 and 7/1 ARMs, short-term rental variants that underwrite Airbnb income, and portfolio or blanket loans covering multiple properties.
Does the loan structure affect my DSCR ratio?
Directly. A 40-year term or an interest-only period lowers the monthly payment, and since DSCR is rent divided by payment, the ratio rises. A property failing at 1.05 on a 30-year fixed may clear 1.25 on a 40-year interest-only structure.
Is a 40-year DSCR loan a good idea?
It helps a thin ratio qualify and improves monthly cash flow, at the cost of building equity far more slowly and paying more interest overall. It suits investors optimising for cash flow rather than paydown, particularly where the plan is to sell or refinance rather than hold to maturity.
When does an interest-only DSCR loan make sense?
When you have a defined exit inside the interest-only window — a planned sale, refinance or repositioning. No principal is repaid during the IO period and the payment jumps at recast, so it fits a permanent buy-and-hold far less well.
Can one DSCR loan cover multiple properties?
Yes, through a blanket or portfolio loan with one payment and one set of closing costs. Release clauses let individual properties be sold without repaying the entire facility, though tying properties together does make later refinancing more complex.
Which structure should I choose?
Work backwards from your exit. A ten-year hold argues for a 30-year fixed; a three-year reposition argues for an ARM or interest-only with a short prepayment penalty; a thin ratio argues for 40-year or interest-only. Model each before committing.
