What to Verify Before Relying on the Result
A calculator is only as useful as its inputs. Use current leases, comparable rents, tax bills, insurance quotes, utility records, lender terms, contractor estimates, and property-specific inspections whenever possible. Include vacancy, management, maintenance, reserves, and transaction costs even when a preliminary listing omits them.
Test a conservative case as well as an expected case. Lower the projected income, increase expenses, extend the renovation or sale timeline, and consider the cash required if refinancing or disposition takes longer than planned.

Numbers Need Context
The output should be reviewed with the property condition, legal use, local requirements, financing maturity, available reserves, management workload, and exit alternatives. A favorable result does not make an unsuitable building or unsupported strategy safe.
Boston REIA provides education and networking, but investors remain responsible for their own analysis and professional advice.
