DSCR is the debt-side underwriting metric banks care most about for income-producing real estate. It tells the lender how much cushion exists between operating cash flow and the debt service requirement. A DSCR of 1.30 means NOI is 30% above debt service — a 30% buffer.
For coliving, DSCR underwriting depends heavily on the lender's view of stabilization risk. Most banks require either (a) trailing-12-month NOI demonstrating stabilized DSCR ≥ target, or (b) interest reserve covering ramp-up to stabilization for purpose-converted property.
Formula
DSCR = Annual NOI ÷ Annual Debt Service
Worked example: Property: €350,000 NOI, €4.5M debt at 5.5% interest with 25-year amortization. Annual debt service ≈ €330,000. DSCR = €350,000 ÷ €330,000 = 1.06. Most lenders require ≥ 1.25 minimum, so this property is over-leveraged for typical underwriting.
In the field
European bank DSCR requirements for coliving: 1.25–1.40 at stabilization, 1.10–1.20 at funding (with interest reserves). UK HMO-specialist lenders 1.25–1.35. Indian INR debt 1.40–1.65 reflecting tighter underwriting.
Common pitfalls
- ×Quoting DSCR on stabilized NOI when actual NOI is below stabilized — underwrites a deal that doesn't pencil today.
- ×Excluding management fees from NOI to inflate DSCR — banks check this and re-underwrite if found.
- ×Using DSCR-friendly amortization assumptions (e.g. interest-only) without modelling refinancing risk.
- ×Ignoring tax + insurance escrow requirements that may sit above debt service in some structures.
