At $137/sf the project earns −44.9% on cost (−47.0% after about $14,000 of loan interest between completion and the last sale, which the budget leaves out) vs. the 15% target. It reaches the target at about $286/sf, $360,000 lower cost; no land price gets there (residual land value −$339,000).

Residual land value: $390,000 sellout − $10,000 selling/closing − $669,623 hard, soft, contingency and financing − $49,565 target profit (15% of cost) = −$339,189. Land source: Public land: price set by the agency; agency and private vacant-land sales, 2019-01 to 2026-07.

Contingency in the budget: 10% of hard cost, meets your 10% minimum. At your 75% maximum loan-to-cost the loan is about $494,000 and the equity needed about $196,000. The budget's loan assumption (80% of cost) is above your maximum; lower "Loan-to-cost" under "Change the plan" on the parcel page to match.

How we got these numbers

Indicative: 1 sale, low confidence. No: it costs about $690,000 and would net about $380,000 after selling costs, $310,000 short before about $14,000 of loan interest between completion and the last sale.

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: insufficient — 1 sale within 3 mi · median $240,000 · $138/SF · 1,742 sq ft · built 2024–2024 · sold 2025-09-24 to 2025-09-24

Search: 1 within 0.25 mi → 1 within 0.5 mi → 1 within 1 mi → 1 within 2 mi → 1 within 3 mi.

Insufficient new-construction comps in this market tier or lower: 1 sale(s) (1 within 0.25 mi; 1 within 0.5 mi; 1 within 1 mi; 1 within 2 mi; 1 within 3 mi); richer markets nearby are not used. The value from them is indicative only (low confidence).

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: Larimer existing homes sell for a median $45/SF; comps were limited to areas priced the same or up to 35% lower ($29–$45/SF existing-home median; Assumption, edit me; never a richer market). New homes sell above existing-home medians, so the comps' own $138/SF is above this band; the band compares neighborhoods, not the comps' prices. Even areas priced no higher than $45/SF have fewer than 5 new-home sales, so no value is estimated from richer markets nearby. Size: too few sales within ±40% of the planned 1,424 sq ft, so all sizes were used. Result: 1 sale from the areas in the same market tier or lower, in Larimer; median $138/SF, middle half $138–$138/SF.

Older homes nearby sold for a median $58 per sq ft (10 sales within 0.25 mi). That is a floor, not the value of a new home.

The most similar sale is 1–99 block of Mayflower St at $138/SF. Fewer than 5 new-construction sales qualify, so the value from them (median $138/SF) is indicative only (low confidence).

Cost: land $3,000 + construction $541,000 + water and sewer laterals $20,000 + design and engineering $22,000 + contingency $56,000 + loan interest $23,000 + closing, permit and carrying costs $21,000 = $690,000 total.
Value: $138/SF × 1,424 sq ft = $196,188 per home, rounded to $195,000; × 2 homes = $390,000 in sales.
Profit: $390,000 sales − $690,000 total cost − $10,000 selling costs = $310,000 short (a loss of 44.9% of cost).

Can you build here?

Yes, a duplex is allowed by right, but the parking per unit needs a variance (3-6 months to a building permit, review time only).

Does it pencil?

No: it costs about $690,000 to build but would be worth only about $380,000, a loss of $310,000.

$380,000 value minus $690,000 cost = $310,000 short.

What's in the way?

A variance is needed for the parking per unit (the Zoning Board granted 100% of 14 past requests like it).
Only 1 recent new-home sale nearby, so the value is indicative (low confidence).
49 valid sales and 111 completed building permits within 1/2 mile in 3 years: busier than 45% of City parcels.

What next?

Apply to the Zoning Board for a variance on the parking per unit.
Ask a local agent or appraiser what new homes like this sell for nearby.
Get a builder's bid for this layout before buying; the cost lines show what drives the total.

Time to a permit

3-6 months Estimate

Building-permit review only (plus any zoning hearing this option needs); zoning review, site-plan, geotech, PWSA and DOMI steps are not included.

Building-permit part: the City's review target for one round (City target, not measured). Each revision request adds time.

44 building permits waiting for City review (as of 2026-09-21).

building permit: City target 21 calendar days per review round (City target, not measured)
dimensional variance: ~1.2 mo (heuristic)
decision to permit after a hearing: ~2.3 mo (ZBA record median)
