Rental cash-flow planning
What one vacant month does to a rental's annual cash flow
A monthly surplus can hide an annual shortfall. Walk through a simple vacancy scenario before committing to your next rental property.

Look beyond a fully occupied month
An occupied rental can show a positive monthly balance while leaving less room than expected for a change of tenant. Before choosing a purchase or refinance, put one vacant month into the annual budget. The point is not to predict exactly when vacancy will happen. It is to see which assumptions your plan depends on.
Pillar offers DSCR rental financing. Start your application with the property and financing plan, or check loan options while comparing scenarios. Bring an operating budget as well as rent information: your own cash-flow test and a lender's qualifying calculation answer different questions.
Start with a transparent baseline
Consider a hypothetical rental with monthly rent of $2,500 and a combined monthly budget of $2,000 for loan payments and recurring property expenses. At full collection for twelve months, rent totals $30,000 and those budgeted outflows total $24,000. That leaves $6,000 before any costs omitted from the example.
The $2,000 is an illustrative combined budget, not a payment quote or a market expense estimate. In your own worksheet, separate principal and interest, taxes, insurance, association charges, management, maintenance, and owner-paid utilities. Identify any planned capital work separately. Avoid counting taxes and insurance both inside an escrowed payment and again as separate expenses.
Remove a month of rent, then add turnover costs
Assume one month produces no rent while the $24,000 annual outflow budget stays unchanged. Collected rent becomes $27,500, leaving $3,500 before additional turnover work. If cleaning and minor make-ready work add an illustrative $1,000, the remaining balance is $2,500. That is $3,500 less than the fully occupied baseline.
Some costs could change during vacancy; this example deliberately holds the recurring budget constant so the lost-rent effect is easy to see. Replace that assumption with property-specific figures where appropriate. If your baseline already includes an allowance for the same vacancy or turnover expense, reconcile it before adding the full scenario cost again.
| Full-year rent: 12 x $2,500 | $30,000 |
|---|---|
| Recurring annual outflows | $24,000 |
| Fully occupied baseline balance | $6,000 |
| Rent collected with one vacant month | $27,500 |
| Additional turnover work | $1,000 |
| Balance after vacancy and turnover | $2,500 |
Check when the cash is needed
An annual balance does not show whether cash is available in the month expenses arrive. In this scenario, the vacant month still carries $2,000 of budgeted outflows. If the $1,000 turnover work is paid then, that month needs $3,000 without rental receipts. Cash remaining later in the year does not pay today's bill.
Map the expected timing of repairs, insurance renewals, and other larger payments. Review cash already available for the rental and decide what amount you want to retain. This is an operating-planning exercise, not a statement of lender reserve requirements or a universal reserve recommendation.
Use the result to improve the financing conversation
Repeat the worksheet with your actual rent evidence, proposed payment, and expense estimates. Compare full occupancy, one vacant month, and a longer transition if that is relevant to the property. Keep assumptions dated and visible; do not treat the remaining balance as guaranteed profit or as the property's qualifying DSCR.
If the plan becomes uncomfortable under a modest change, revisit the purchase budget, financing structure, or work schedule before committing. Bring those scenarios to Pillar's DSCR review. Start your application when you are ready for a property-specific conversation, or check loan options to clarify the next step.
