Development Feasibility, Yield on Cost and Land Value

Development feasibility asks whether a completed project will be worth enough more than it costs to justify the risk of building it. The core tests are yield on cost, which divides stabilized NOI by total project cost, the development spread over market cap rates, profit on cost, and residual land value, the maximum price a developer can pay for land.

What does a development feasibility study answer?

A feasibility study decides whether a project should proceed and on what terms. It estimates the total cost to build and lease up the project, the income it will produce once stabilized, and the value of that income in the market. If the expected value does not exceed cost by enough to compensate for construction, leasing, financing and market risk, the project should be redesigned, repriced or abandoned. Lenders use the same analysis to size construction loans and test whether the project can be refinanced or sold at completion. Equity investors use it to judge whether the developer's projected profit is credible and adequate for the risk.

What goes into total development cost?

Total development cost includes land acquisition and closing costs, hard costs for construction, soft costs and financing costs. Hard costs cover site work, building construction, contractor fees, general conditions and contingency. Soft costs cover architecture, engineering, permits, impact fees, legal, insurance, taxes during construction, marketing and the developer fee. Financing costs include loan fees and interest during construction and lease up, usually funded through an interest reserve in the budget. Developer fees and any affiliated contractor fees should be identified separately so investors understand how much profit the sponsor earns regardless of the project's outcome.

Contingency should be sized to the project's stage and complexity. A project with full construction drawings and a guaranteed maximum price contract needs less hard cost contingency than one priced from schematic drawings. Underwriters should also verify that the budget includes operating deficits during lease up, since a building that opens empty consumes cash until occupancy and rents stabilize. Leaving these costs out flatters yield on cost and leaves the project underfunded at the moment it is most vulnerable. Absorption assumptions should be supported by the actual lease up pace of recent comparable projects rather than by a target in the business plan.

• Land and acquisition costs
• Hard costs including site work and contingency
• Soft costs including design, permits, fees and developer fee
• Financing costs including interest reserve and loan fees
• Lease up costs including operating deficits, leasing commissions and concessions

What is yield on cost and how is it used?

Yield on cost, sometimes called return on cost or development yield, divides projected stabilized net operating income by total development cost. It is the unlevered yield the developer creates by building the project rather than buying a completed one. The key comparison is between yield on cost and the market cap rate for similar stabilized assets. The difference, called the development spread, measures the margin that rewards the developer for taking construction, leasing and timing risk. Because NOI is projected rather than observed, the analyst should support rents and expenses with current comparable data rather than trended future figures that already assume growth.

Required spreads vary with project risk. A pre leased build to suit for a strong tenant may proceed on a modest spread, while a speculative project in an untested submarket needs a much wider one. Many developers and lenders think about this in basis points, and the appropriate threshold depends on the asset class, market depth, construction risk and the length of the lease up period. A spread that disappears under a modest rise in cap rates or a small cost overrun signals a fragile project.

How do profit margin and levered returns fit in?

Profit on cost converts the spread into dollars. The analyst capitalizes stabilized NOI at a market cap rate to estimate stabilized value, subtracts total development cost to get the developer's profit, and divides by cost. This metric is intuitive for investment committees and makes it easy to compare a project's profit with the risks it carries, such as a year of construction followed by a year of lease up. A profit margin that looks large in dollars may still be thin relative to the time and risk involved, so committees often compare profit on cost to the length of the development period.

Equity investors also look at levered internal rate of return and equity multiple, which depend on construction loan terms, timing of equity draws and the exit strategy. These measures can look attractive even when yield on cost is thin, because leverage magnifies a small spread. That is why lenders and disciplined investors anchor first on unlevered yield on cost and only then examine levered returns. A project that only works with high leverage is usually a project that does not work, because the same leverage that magnifies returns also magnifies the effect of overruns and delays on the equity.

How is residual land value calculated?

Residual land value works backward from the end product to the maximum price a developer can pay for land. Start with stabilized NOI and divide by the minimum acceptable yield on cost to find the maximum total project budget. Subtract all non land costs, including hard costs, soft costs, financing and lease up costs. What remains is the most the developer can pay for the site while still meeting its return target. If the asking price for the land exceeds this residual, the project does not work at that price unless the design, density, rents or costs change.

Residual analysis is especially useful for comparing sites and testing zoning scenarios. Additional density raises NOI and therefore land value, but only if the market can absorb the extra units at the assumed rents and the incremental construction cost, such as structured parking or a taller building type, does not consume the gain. Running the residual calculation across several rent and cost scenarios produces a range of supportable land prices, which is far more useful in negotiations than a single point estimate built on the base case alone.

How should lenders stress test a development project?

Construction lenders test feasibility under adverse conditions because development risk is front loaded and cash flow does not exist until the project leases. Typical stresses include hard cost overruns, construction delays that increase interest carry, slower absorption, lower rents, higher cap rates at completion and higher permanent loan rates at takeout. The key question is whether the project can still be refinanced into a permanent loan that repays the construction loan in full. Lenders also assess the sponsor's ability to fund overruns through completion guarantees, the general contractor's strength, the payment and performance bonding and the quality of the construction budget review.

Testing yield on cost and solving for residual land value

1. A 200 unit project costs $8,000,000 for land, $48,000,000 hard costs, $10,000,000 soft costs and $4,000,000 financing, for total development cost of $70,000,000.
2. Stabilized NOI is $4,400,000. Yield on cost = $4,400,000 / $70,000,000 = 6.29%.
3. The market cap rate for similar stabilized assets is 5.25%, so the development spread is 6.29% - 5.25% = 1.04%, or about 104 basis points. Stabilized value = $4,400,000 / 0.0525 = $83,809,524.
4. Profit = $83,809,524 - $70,000,000 = $13,809,524, and profit on cost = $13,809,524 / $70,000,000 = 19.7%.
5. If the developer requires a 6.75% yield on cost, the maximum total budget is $4,400,000 / 0.0675 = $65,185,185. Non land costs are $62,000,000, so residual land value = $65,185,185 - $62,000,000 = $3,185,185, far below the $8,000,000 land price.

How underwriters apply this

• Anchor on unlevered yield on cost and development spread before looking at levered IRR.
• Confirm the budget includes contingency, interest reserve, lease up deficits and leasing costs.
• Compute residual land value to test whether the land price is supportable at the target return.
• Stress hard costs, timing, absorption, rents and exit cap rates together, not one at a time.
• Test whether the completed project can be refinanced to repay the construction loan in full.
• Evaluate completion guarantees, contractor strength and bonding as part of the credit.
