The “Uh-Oh” Moment That Sparked This Guide
Last month a first-time investor—James—sent me a deal:
“Ken, the seller wants to close in ten days. Does this cash-flow? Will the lender approve me?”
I asked one question:
“What’s the DSCR?”
Silence. Then… “What’s that?”
If you’ve ever felt that knot in your stomach, today’s for you. DSCR (Debt-Service Coverage Ratio) is the #1 metric most lenders use on rental properties. Nail this once, and you’ll know in minutes whether a deal flies or dies.
Step 1: Gather Two Numbers
- Annual Net Operating Income (NOI)
Rental income – operating expenses (taxes, insurance, maintenance, management, vacancy). - Annual Debt Service
Total of 12 mortgage payments (principal + interest) + any escrowed taxes/insurance if they’re in the payment.
Step 2: Plug Into the Formula
DSCR=NOIAnnual Debt ServiceDSCR=Annual Debt ServiceNOI
Easy, right? Here’s the magic: lenders love ≥ 1.00×. Some will go down to .90, but the sweet spot is 1.10+.
Step 3: Quick Real-World Example
- 4-plex rents = $6,200/mo
- Operating expenses = $1,900/mo
- NOI = $6,200 – $1,900 = $4,300/mo → $51,600/yr
Mortgage quote: $3,350/mo → $40,200/yrDSCR=51,60040,200≈1.28DSCR=40,20051,600≈1.28
Result: ✔️ Pass! Lender likely green-lights this loan.
Pro Tips That Keep Deals Alive
- Raise Rents – Even $50/unit can bump DSCR over the line.
- Buy Down Rate – A small point lowers payment, boosts ratio.
- Cut Expenses – Self-manage or appeal property taxes post-close.
Why DSCR Sets You Free
Unlike conventional loans that dive into your W-2 income, a DSCR loan says, “Show me the property pays for itself.” That means:
- Less paperwork for you
- LLC ownership OK
- Scale doors faster without hitting the dreaded “10-loan” limit
