How we got these numbers

Can't tell yet: it costs about $580,000, but demolition of the existing building is not priced yet (no local cost). Enter a demolition cost to see whether it pencils.

Ranges come from each input's documented range; the “likely” figure uses the defaults. Rent to the nearest $50, sale price to $5,000 a home, cost lines to $1,000, totals to $10,000 — the math uses the rounded numbers. The profit (or gap), margin and yield ranges combine the cost and value ranges as independent uncertainties: each side moves by the square root of (value change² + cost change²), so a low value is not paired with a high cost.

This layout is small for new construction nearby: 1,012 vs 2,120 sq ft typical per home. The value assumes a home this size sells for the same price per sq ft.

New-construction comps: 11 sales within 3 mi · median $630,000 · $259/SF · 2,120 sq ft · built 2016–2025 · sold 2024-11-26 to 2026-06-29

Search: 0 within 0.25 mi → 0 within 0.5 mi → 0 within 1 mi → 4 within 2 mi → 22 within 3 mi.

Search widened to 3 mi (0 within 0.25 mi; 0 within 0.5 mi; 0 within 1 mi; 4 within 2 mi; 22 within 3 mi).

Rule: sales in the same neighborhood (or municipality) when it has 5+; otherwise sales from areas in the same market tier or lower (never a richer market), else the nearest by distance; widen until 8, keep the nearest 12; drop sales beyond 1.5× the middle-half spread of $/SF. Market tier: Crawford-Roberts existing homes sell for a median $191/SF; comps were limited to areas priced the same or up to 35% lower ($124–$191/SF existing-home median; Assumption, edit me; never a richer market): Duquesne Heights, Mount Washington, Polish Hill, South Side Flats. New homes sell above existing-home medians, so the comps' own $259/SF is above this band; the band compares neighborhoods, not the comps' prices. Size: too few sales within ±40% of the planned 1,012 sq ft, so all sizes were used. Result: 11 sales from the areas in the same market tier or lower, nearest first, in Duquesne Heights, Mount Washington, Polish Hill, South Side Flats; median $259/SF, middle half $248–$291/SF; 1 dropped as outliers.

Dropped: 2026-03-09 · $350,000 · $135/SF is below the outlier limit ($158–$364/SF, 1.5× the middle-half spread).

Older homes nearby sold for a median $204 per sq ft (17 sales within 0.25 mi). That is a floor, not the value of a new home.

The most similar sales are 3000 block of Paulowna St, 2500 block of Larkins Way and 1–99 block of Greenbush St at $259–$300/SF. Projected pricing of $250,000–$295,000 per home ($248–$291/SF, the middle half of all 11 sales; the study uses the median, $259/SF, × 1,012 sq ft) reflects new construction (every sale was built within 10 years of its sale) and a smaller home than the typical sale (1,012 vs 2,120 sq ft), priced at the same $/SF. Parking is not in the County sale records, so it is not adjusted.

Can you build here?

Yes, a duplex is allowed by right and fits the lot's size and setback rules (under 1 month to a building permit, review time only).

Does it pencil?

No: it costs about $580,000 to build but would be worth only about $507,000, a loss of $73,000.

$507,000 value minus $580,000 cost = $73,000 short.

This layout is small for new construction nearby: 1,012 vs 2,120 sq ft typical per home. The value assumes a home this size sells for the same price per sq ft. Partial estimate. Not included yet: demolition of the existing building.

What's in the way?

The layout is small next to new homes that sold nearby, so the sale value is uncertain.
26 valid sales and 144 completed building permits within 1/2 mile in 3 years: busier than 49% of City parcels.

What next?

Get the phase I Environmental Site Assessment from Environmental consultant.
Get local quotes for the cost items the estimate leaves out.
Get the asbestos survey + Health Dept notification from Certified inspector; Allegheny County Health Dept.

Time to a permit
