DSCR loans have become the default financing for many rental investors because they're underwritten on the property's income, not your personal income. Here's how they work.
What DSCR measures
The debt-service coverage ratio is the property's net operating income divided by its total debt service (mortgage principal + interest, and sometimes taxes and insurance). A DSCR of 1.25 means the property generates 25% more income than its debt payments.
Why investors use DSCR loans
- No personal income docs: qualification is based on the property's cash flow, not your W-2 or tax returns — useful for self-employed investors or anyone scaling past conventional limits.
- Portfolio-friendly: easier to keep buying once you've maxed out conventional mortgages.
- Faster, simpler underwriting in many cases.
What ratio you need
Most lenders want a DSCR of at least 1.0–1.25. Below 1.0 means the property can't cover its own debt, and you'll either be declined or need a larger down payment to get the ratio up. The stronger the DSCR, the better the rate and terms you'll be offered.
The trade-offs
DSCR loans usually carry slightly higher rates and fees than owner-occupant conventional loans, and often require 20–25% down. The premium buys flexibility and scalability. Run the numbers: the higher rate has to still leave you with positive cash-on-cash return.
