Subdivision Development & Land Residual
~11 min read · Run the development method and the land residual technique for income land.
Two income-family tools value land by what it can EARN: the subdivision development method discounts a lot-sale program to present value, and the land residual technique lets the building take its return first and capitalizes what's left into land. Both are only as good as their many inputs.
Subdivision development method
For land whose HBU is subdivision: project the gross sellout (finished lots × expected prices over an absorption schedule), subtract all costs — development (streets, utilities, grading), carrying costs and taxes, marketing and sales, and developer's profit — then discount the net cash flows to present value at a market-derived yield. The residual PV is what a developer can pay for the raw land today. Absorption speed and lot pricing dominate the answer; both need market support.
- PV of (lot revenues − development costs − profit) over the sellout
- Absorption schedule drives the discounting
- Output: what the land is worth to the developer NOW
Land residual technique
Classical residual logic: total NOI − income required by the improvements (improvement value × building cap rate) = income attributable to the land, capitalized at the land rate into land value. Requires knowing improvement value/cost and both rates — hence its modern role: feasibility testing (what land price does a proposed building support?) more than everyday appraisal. Its sibling, the building residual, reverses the knowns.
- Land income = NOI − (improvement value × building rate)
- Land value = land income ÷ land rate
- Feasibility workhorse; assumption-heavy in practice
Ground rent capitalization
Where ground leases exist (land leased to owners of the buildings on it), land value = ground rent ÷ land cap rate — direct capitalization applied to the purest land income there is, with reversion analysis for lease-end. Markets with active ground-lease sectors make this the cleanest income evidence of land value.
Worked example
A 20-lot approved subdivision: finished lots will sell at $120,000 each, 10 lots/year for 2 years. Development costs $700,000 (year 0–1), selling costs 6% of revenue, developer profit 15% of revenue, yield 10%. Roughly what can a developer pay for the raw land?
Revenues: $1,200,000/year for 2 years. Deductions per year: selling 6% (72,000) + profit 15% (180,000) = 252,000 → net lot cash flow 948,000/year. Development cost: allocate 700,000 up front (conservative). PV at 10%: year 1: 948,000 ÷ 1.10 = 861,818; year 2: 948,000 ÷ 1.21 = 783,471; total inflow PV ≈ 1,645,289; minus development 700,000 → raw land ≈ $945,000, call it $950,000 (≈$47,500/lot raw). Sensitivity: stretch absorption to 5 lots/year over 4 years and the PV drops toward $800,000 — absorption is the lever, which is why the exam asks what happens to land value 'if sellout slows.' Slower sellout, lower land value, every time.
Common exam pitfalls
Skipping developer's profit.
The developer works for a return — omitting profit overprices the land by exactly that margin.
Valuing raw land at finished-lot prices.
The method's whole point: finished revenue minus costs, profit, and TIME equals raw value — the gap is enormous.
Using the residual technique with guessed inputs.
Two capitalization rates and an improvement value — each guess compounds; use it for feasibility, corroborate for value.
Sell the lots on paper, pay the costs and the developer, discount the wait — the leftover is the land.
Recap
- Development method: PV of net sellout cash flows
- Deduct development, carrying, selling costs, AND profit
- Absorption speed is the dominant sensitivity
- Land residual: NOI minus improvement income, capitalized
- Ground rent capitalization where ground leases trade
- Income-family tools corroborate sales comparison
