How we got these numbers

Can't tell yet: it costs about $680,000, 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.

New-construction comps: 6 sales within 3 mi · median $710,000 · $331/SF · 2,095 sq ft · built 2019–2023 · sold 2024-02-23 to 2026-06-26

Search: 3 within 0.25 mi → 4 within 0.5 mi → 4 within 1 mi → 5 within 2 mi → 6 within 3 mi.

Search widened to 3 mi (3 within 0.25 mi; 4 within 0.5 mi; 4 within 1 mi; 5 within 2 mi; 6 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: East Liberty existing homes sell for a median $228/SF; comps were limited to areas priced the same or up to 35% lower ($148–$228/SF existing-home median; Assumption, edit me; never a richer market): East Liberty, SHALER, Stanton Heights. New homes sell above existing-home medians, so the comps' own $331/SF is above this band; the band compares neighborhoods, not the comps' prices. Size: kept homes of 1,556–3,630 sq ft (±40% of the planned 2,593 sq ft; Assumption, edit me). Result: 6 sales from the areas in the same market tier or lower, nearest first, in East Liberty, SHALER, Stanton Heights; median $331/SF, middle half $304–$356/SF.

Older homes nearby sold for a median $243 per sq ft (37 sales within 0.25 mi). That is a floor, not the value of a new home.

The most similar sales are 300 block of N Saint Clair St, 300 block of N Saint Clair St and 300 block of N Saint Clair St at $354–$359/SF. Projected pricing of $790,000–$925,000 per home ($304–$356/SF, the middle half of all 6 sales; the study uses the median, $331/SF, × 2,593 sq ft) reflects new construction (every sale was built within 10 years of its sale) and a larger home than the typical sale (2,593 vs 2,095 sq ft), priced at the same $/SF. Parking is not in the County sale records, so it is not adjusted.

Shown: the 6 most similar of the 6 sales in the value set, detached homes first, then nearest, then most recent sale. The median and middle half below use all 6. Addresses show the block only; the PDF report lists full street addresses.

Cost: land $66,000 + construction $493,000 + street occupancy and staging $3,000 + water and sewer laterals $10,000 + design and engineering $20,000 + contingency $51,000 + loan interest $19,000 + closing, permit and carrying costs $22,000 = $680,000 total.
Value: $331/SF × 2,593 sq ft = $859,042 per home, rounded to $860,000; × 1 home = $860,000 in sales.
Profit: $860,000 sales − $680,000 total cost − $22,000 selling costs = $158,000 profit (23.2% of cost).
