Rented normally, you'd make about $1,099 a month, and it holds up.

The rent is our own estimate — worth checking against two or three real local lettings. One month without a tenant wipes out about 2 months of that profit, so keep a buffer for gaps. It has been listed 103 days without selling, which is your argument for offering less.

We could not confirm the local rent, so check it before you offer — the 29.75% return before costs on price rests on it.

Why it works

Monthly profit +$1,099/mo from completion — the no.1 reason to invest
This is the money left after the mortgage, the running costs and tax — not the rent.It assumes the rent we modelled and the empty weeks we assumed. Change either and it moves. Try your own numbers →
Stress Rent-covers-mortgage check PASS at 6.5% rate stress — lender-friendly
Lenders test the rent against a stressed rate, not the one you are quoted. This clears it.The cover level is each lender’s own policy, not law — treat it as the shape of the test. See the lender's view →

Why to be cautious

No rent comparables — estimate is a rule-of-thumb fallback, not market data. Verify the rent locally before offering.
