Loses money — only works at a lower price

Rented normally, it costs you $4,927 a month. That is $59,127 a year, every year you hold it.

The rent is our own estimate, not a signed tenancy. The shortfall is not a data problem: at this price, on these costs, the rent does not cover what it takes to hold it. It only works if you are buying for the capital growth, or buying it cheaper.

Why it works

4.03% return before costs — around the area average for this property type
Nothing here is unusual enough, in either direction, to be a reason on its own.

Why to be cautious

Monthly profit −$4,927/mo — you would top this up heavily, every month, from your own income
You would be topping it up every month, from your own income, for as long as you hold it.That can still be the plan if you are buying for capital growth — but it should be a decision, not a surprise. Try your own numbers →
No rent comparables — estimate is a rule-of-thumb fallback, not market data. Verify the rent locally before offering.

What would have to be true?
No offer works back from a stand-in rent
Every price on this card is that rent inverted. This listing’s rent is a wider-area figure rather than a like-for-like comparison of nearby rentals, and a price worked back from it would be quoted to the $5,000 on evidence that cannot carry it.
