How we test a home
Every home we list gets the same test.
- Rent
- A 12-month unfurnished lease, based on two independent rent estimates. Never a seasonal or short-term rent.
- Property tax
- Tax is estimated at the buyer's reassessed value. Where the listing's own tax bill is higher, we use the bill.
- Insurance
- An estimate from local rates for a home this size. It is not in a flood zone.
- HOA
- Not listed; we assume none.
- Loan
- 7.25% interest over 30 years, at 20, 25 and 30% down.
- Nets positive
- When its rent covers the whole monthly payment: loan, tax, insurance and HOA (PITIA). We use gross rent, as a DSCR lender does, with nothing set aside for vacancy, repairs, capex or management.
