A projection without a maintenance reserve and a vacancy assumption is a marketing document. Stress-test with revenue 20% below plan before committing.

Annual cash flow is gross revenue minus operating costs, management, maintenance reserve and debt service. Cash invested includes deposit, closing costs and furnishing.

The failure mode in rental investment modelling is optimism about revenue and silence about cost. Both the reserve and the management line exist even when you do the work yourself — your time is a cost the model should carry.

Questions operators ask

Should I include my own labour if I self-manage?
Yes. Use the management fee field at the market rate. If the deal only works because you work for free, it does not work.
