About DSCR Calculator — Debt Service Coverage Ratio
DSCR is the investment-property gatekeeper: net operating income divided by annual debt service, with 1.25× the standard floor — the property must earn 25% more than its mortgage costs before a commercial or DSCR lender funds it. The defaults ($30k NOI against a $300k loan at 7.25%) score 1.22×: a hair under, exactly the zone where deals get restructured. The back-solved MAX LOAN is the number that runs acquisitions: lenders size loans from NOI ÷ minimum DSCR reverse-amortized — not from your income (the entire point of 'DSCR loans' for investors who are property-rich and W-2-light: the BUILDING qualifies, not the borrower). At the defaults, $30k of NOI supports ~$293k of debt; every $1,000 of added NOI supports roughly $9,800 more loan — the leverage math behind value-add strategies. Levers when you're under the floor (in lender-preference order): bigger down payment (mechanically lifts DSCR), rate buydown or longer amortization (40-year and interest-only DSCR products exist — coverage improves, equity build slows), documented NOI improvements (signed leases at higher rents move underwriting; 'market rent potential' doesn't), or interest-rate float-downs. And mind the trap inside the ratio: DSCR at today's rate passes, but commercial loans REPRICE at 5-7 year maturities — stress your coverage at +2% before celebrating a 1.26×.

Frequently asked questions
What DSCR do lenders actually require?+
1.20-1.25× is the residential-investor (DSCR-loan) standard; commercial banks 1.25-1.35×; agency multifamily can stretch to 1.20× for strong assets; rough credit/asset classes push 1.40×+. Below 1.0× products exist (negative-cashflow 'no-ratio' loans) at painful pricing. Each 0.05× of requirement ≈ 4% less loan — shop the FLOOR as hard as the rate.
DSCR loan vs conventional mortgage — investor ke liye kya sahi?+
DSCR loan: building qualify karti hai (rent roll/appraisal-rent), aapki tax returns nahi — self-employed, multi-property, ya write-off-heavy investors ke liye bana hai; rate ~0.5-1.5% premium + prepay penalties aam. Conventional (agency): sasta, par DTI me aapki income chahiye aur 10-property cap. Pehli 2-4 properties conventional se, scale DSCR se — typical ladder yahi hai.
1.22 aaya hai, 1.25 chahiye — sabse sasta fix kya hai?+
Order: (1) seller-credit/price-cut maango — loan chhota, DSCR upar; (2) amortization 30→40 ya 10-yr IO option (DSCR products me milta hai) — coverage turant sudhrega; (3) rate buydown points (math karo: point cost vs loan-size unlock); (4) down badhao — aakhri, kyunki cash-on-cash girta hai. NOI 'badhane' ke vaade underwriting me nahi chalte — signed lease chahiye.
Kya DSCR personal income bilkul nahi dekhta?+
Ratio nahi dekhta, par lender phir bhi dekhta hai: credit score (typically 660-700+ floors), reserves (6-12 months PITI), experience (pehli rental par kuch lenders strict), aur entity/guaranty structure. 'No-doc' nahi hai — 'no-tax-return' hai. Aur prepayment penalties (3-2-1 ya 5-4-3-2-1) DSCR loans ki signature hai — exit plan ke saath hi sign karo.
