Analyze the property with AIThe formula
Cash Flow = (Rent − Vacancy − Operating Expenses) − Debt Service
Every metric on this page derives from that line. Change one input and watch which metric breaks first.
Worked example
- $725,000 purchase, 20% down, 4.9% over 30 years.
- Rent $4,500/month, 3% vacancy, operating expenses $9,600/year.
- NOI $42,780, debt service $37,680, cash flow about $425/month.
- Cap rate 5.9%, DSCR 1.14, cash-on-cash roughly 3.1%.
How to read the result
The most common underwriting error is an operating expense line that is too thin. Property tax, insurance, maintenance, management and utilities on a small residential building frequently land between 25% and 40% of effective gross income.
Test the deal against a rate increase and a rent decrease before you make an offer. If either breaks it, you are relying on conditions rather than on the asset.
Treat any figure you have not verified against a document or a comparable as an assumption, and write it down as one.
Frequently asked
What expenses should I include?
Property taxes, insurance, any owner-paid utilities, repairs and maintenance, property management, snow and landscaping, and a capital reserve. Mortgage payments are not operating expenses.
How much should I budget for maintenance?
Base it on the building's age, systems and condition rather than a flat percentage, then sanity-check it against actual invoices if the seller provides them.
