Start with durable, financeable cash flow
Build the analysis from realistic rent, vacancy, operating expenses, reserves, debt service, and management—not the most optimistic version of the listing. A property can show an attractive cap rate and still produce weak cash flow after financing.
Stress-test the numbers for a slower lease-up, an unexpected repair, or a higher renewal rate. The objective is not to predict every surprise; it is to understand how much room the investment has before the plan breaks.
- Verify current rent against signed leases
- Separate recurring expenses from one-time costs
- Include management and capital reserves even if you self-manage
Study the tenant and the micro-market
Demand is local. Review comparable rents, days on market, employer access, school and transportation patterns, new supply, and the type of renter the property is likely to attract.
A strong-looking spreadsheet cannot compensate for a property that is difficult to lease or located where competing supply is growing faster than demand. The best underwriting connects property-level numbers to the behavior of the local market.
Know the building, financing, and exit
Inspect the roof, mechanical systems, exterior, utilities, insurance exposure, and deferred maintenance. Then model the financing terms you can actually obtain—including rate, amortization, closing costs, and any balloon or refinance risk.
Finally, define more than one exit. Could you hold through a soft market? Would another buyer value the property at a conservative cap rate? A compelling investment should make sense before appreciation becomes the rescue plan.
