The payment is still due, every month, in full. That is what happens when your DSCR-financed rental goes vacant. The loan qualified on the property's rent, but the obligation never depended on the rent arriving, and vacancy is precisely the risk the whole structure prices. Nothing pauses. The note does not know the tenant left. What changes is the source of the payment: it stops coming from the rent and starts coming from you. How long you can sustain that is a number you can compute long before it ever happens.
Why doesn't the payment pause when the rent stops?
Because DSCR underwriting used rent to size the loan, not to source the payments. The ratio, rent over PITIA, answered one question at origination: can this property plausibly carry this debt? Once the loan funds, you owe the payment as borrower or guarantor whatever the occupancy. That is not a defect in the product. It is the deal. The provider accepted property-based qualification and priced in the chance that the property sometimes produces nothing.
How long is your runway? Measure reserves in months
Reserves are the survival mechanism, and the useful unit is months of PITIA rather than dollars. Divide what you actually hold in liquid accounts earmarked for this property by the full monthly PITIA. The result is how many vacant months you can absorb before the payment starts competing with the rest of your life. The reserves and liquidity guide covers how reserves are counted at origination; this calculation is the after-closing version, and it is worth redoing every quarter, because reserves drain quietly between vacancies.
A fenced runway calculation
The numbers that follow are illustrative arithmetic only, not advice, a rule, or a program figure. Say PITIA is $2,300 a month and the earmarked liquid reserve is $13,800. The raw runway is $13,800 divided by $2,300: exactly six months. But a vacancy rarely costs only the payment. Turnover has its own bill. Take $2,500 of paint, cleaning, repairs, and leasing costs off the top and the effective reserve is $11,300, which is about 4.9 months. Plan around the shorter number.
| Runway line | Amount |
|---|---|
| Monthly PITIA | $2,300 |
| Earmarked liquid reserves | $13,800 |
| Raw runway: $13,800 ÷ $2,300 | 6.0 months |
| Turnover costs off the top | −$2,500 |
| Effective reserve | $11,300 |
| Effective runway: $11,300 ÷ $2,300 | 4.9 months |
Vacant month or rent cut: the relet arithmetic
Each vacant month costs one twelfth of the year's rent, about 8.3% of annual rent. That is pure arithmetic, not a market claim, and it reframes the pricing decision during a vacancy. Holding out for an extra $100 a month while the unit sits empty at a $1,900 ask means one more vacant month burns $1,900, while the $100 premium would take 19 months to earn it back. Run that comparison with your own numbers each week the unit sits. It usually argues for filling the unit sooner at a defensible rent rather than defending a number on a listing.
When should you call the servicer?
Early, and before a payment is missed. If the runway math says trouble arrives in month three, the call belongs in month one. A servicer generally has more room to work with a borrower who is current and communicating than with one who has already missed payments, and what any particular servicer can offer is that servicer's own decision; nothing here promises an outcome. Sequencing is the whole point. A missed payment converts a liquidity problem into a credit problem, and credit problems follow you into the next deal.
The real fix happens before you buy
Vacancy is survivable when it was stress-tested into the purchase. Before you buy, drop the rent in the model and watch how the coverage behaves, then run zero-rent months against your reserve in the stress matrix to see how the runway holds under combined moves. A deal that only works at full occupancy and current rent does not have a vacancy problem. It has a fragility problem that vacancy will eventually reveal.
A vacancy does not change what you owe; it changes who pays. The rent paid the note yesterday, your reserves pay it today, and the length of that bridge was decided the day you closed.
