Is $645,000 supportable for this 1,880 sq ft New York coastal home?

One detail has made the $645,000 asking price harder to judge: this is a 5-bed coastal home squeezed into about 1,880 sq ft. The New York property is in average condition, with good light and location, but dated finishes and potential vacancy costs if it is rented.

I have three active listings to compare with it, yet just one completed transaction. Before adjusting for size, I need to know whether the five-bedroom layout is genuinely useful and whether that sale shares the same micro-location and coastal exposure. Parking, outdoor space and any service charge could also shift the comparison.

What would you verify first, and how would you keep the sales valuation separate from the rental and vacancy assumptions? I will still seek an independent local appraisal before treating the result as reliable.

One extra point: my rental calculation assumes eleven occupied months each year, but the repair reserve may still be too light. I’m therefore trying to keep the sales comparison and income case separate rather than using projected rent to justify the asking price.

The completed sale should carry much more weight than the three listings, provided its micro-location and property type are genuinely comparable. I wouldn’t apply a generic price-per-square-foot adjustment yet. First establish how buyers value the extra bedrooms, because five beds within 1,880 sq ft may not have the same utility as a larger five-bed house.

Is there parking, usable outdoor space, or any service charge? Those could move the comparison materially.

I’d go further: “coastal New York” is too broad for a defensible adjustment range. Even nearby homes can differ because of immediate surroundings, access and coastal exposure. The missing fact that would most change my view is the precise micro-location, followed by whether ownership and insurance-related costs differ from the comparable.

Dated finishes are visible and estimable; location disadvantages are harder to cure.

I don’t fully agree that the completed sale automatically deserves dominant weight. A closed sale is better evidence than an asking price, but one poor match can mislead more than several relevant listings.

Make a simple comparison grid: floor area, bedroom layout, condition, parking, outdoor space, immediate location and sale/listing date. Mark each property superior, similar or inferior before attaching money. For condition, use a realistic scope of work rather than a blanket percentage.

On the rental side, eleven months handles some vacancy but not necessarily the costs of each turnover. Keep vacancy, repairs and any service charges as separate lines so one allowance is not quietly covering three risks. Also clarify the lease length or expected tenancy pattern; frequent turnover could matter more than the headline rent.

I’d request the missing details on parking and outdoor space, then test whether the deal still works using the completed sale alone and a more conservative repair reserve.
