Incremental Capital Project Returns

Canonical ownership reviewed October 17, 2026. The methods and original teaching case retain their stated October 7 scope. Sector methods supply physical feasibility, work scope and tenant evidence; the equations do not establish a project approval or market return hurdle.

Baseline and Measure

For discretionary upgrades, compare the project with a defined no-upgrade case. Methods scope reviewed 2026-10-07: incremental NOI, capitalized value, dated project cash and capital recovery answer different questions; none alone establishes approval.

Stabilized Income and Static Value

Stabilized Incremental NOI Yield =
  Incremental Stabilized Annual NOI / Defined Incremental Project Cost

Require a positive cost denominator, the same project scope and an explicit stabilized annual period. Include the relevant installation, leasing and disruption costs in the stated budget. This operating-income/cost screen is not automatically an unlevered cash yield or IRR: reconcile lease incentives, TI/LC, later capital spending, collections and downtime in cash. Avoid treating an already budgeted cost or lost rent as incremental a second time.

Static Implied Value Surplus =
  Incremental Stabilized Annual NOI / Assumed Compatible Cap Rate
- Defined Incremental Project Cost

This shortcut requires a positive compatible cap rate and the same rate for the with/without cases: (NOI_with / c) − (NOI_without / c) = Incremental NOI / c. If the rates differ, calculate each property value separately. State the valuation date and supported stabilization assumptions. Subtracting an undiscounted budget from a future implied value does not produce today's NPV or realized sale profit. A finite holding period requires operating cash, actual payment dates and net incremental sale proceeds at exit, not an extra terminal value on top of a capitalized perpetual stream. See income valuation scope.

Dated Incremental Property Cash

Incremental Project NPV =
  Incremental Net Property Cash_0
+ sum(Incremental Net Property Cash_t / (1 + r)^t, t = 1..T)
+ Incremental Net Sale Proceeds_T / (1 + r)^T

For this displayed annual model, require a positive integer T, year-end cash and a matching annual rate r > −1; irregular payments need dated factors. Include project spending and relevant capital/lease payments once in the cash line. Net sale proceeds exclude the operating cash already counted in that year. Match property cash with a property discount basis; debt-funded spending and equity distributions belong in a separately reconciled financing model. Funding a reserve and spending the same funds are not two costs. For a separately scoped after-tax investor comparison, CRE Tax and After-Tax Underwriting owns deduction allowance, usable benefit and payment timing. Actual work cost and a proposed deduction are not two work payments; a deduction is not a second cash receipt after reduced tax payments. Physical Risk Value Scenarios applies the same incremental-cost discipline to physical-risk scenarios.

Recovery and Worked Alternatives

For recovery, use the shared cumulative-cash payback model. Initial Cost / Annual Net Cash Inflow applies only to constant positive cash benefits starting in year one, no later investment, and a stated receipt convention. NOI is the cash denominator only when explicitly reconciled to those net receipts. Delayed benefits, later replacements or an unrecovered balance within the hold must remain visible; payback omits later wealth effects and does not substitute for NPV.

Curator teaching case, not market evidence: assume a $1M time-zero project cost, incremental stabilized annual NOI $150K and an independently assumed compatible cap of 6%. The NOI yield is 15% and the static surplus is $1.5M. Separately assume net incremental property cash of $100K at each year-end 3–5, no receipts in years 1–2, a year-5 sale, next-year incremental NOI still $150K, unchanged 6% cap, no incremental selling costs and a matching 8% annual discount rate. Incremental sale proceeds are $2.5M and timed NPV is approximately $922,402.52. With no sale and the $100K annual receipts instead continuing unchanged, operating-only first-crossing payback is at year 12, not the $1M/$150K ≈ 6.67-year NOI shortcut. With the stated year-5 sale included, recovery occurs at year 5; identify which cash population is being measured. The two hold scenarios are alternatives, not combined outcomes.

Support the rent or cost-saving mechanism with the target tenant universe, lease terms and project-specific evidence. Costs, cap rates, discount rates, useful life and feasibility remain assumptions until independently supported. Existing Source: Debt Yield Scope Review 2026 supports income/capital and direct-cap/DCF distinctions; Source: Payback Mechanics Review 2026 supports relevant cash, timing and recovery conventions. The equations and case above are curator derivations, not source-prescribed project thresholds. This scoped revision does not re-attest other inherited physical-condition, legal or cost-range claims.

Gross Rent Screen Versus Net Income

Additional hypothetical per-unit case, USD: assume a constant 300/month gross rent premium for twelve paying months, full collection, incremental annual operating expense 600 and no other income adjustments. Defined incremental project cost is 25,000. Gross annual rent uplift is 3,600, so gross rent divided by cost is 14.4%. Incremental annual NOI under these assumptions is 3,000 and its stabilized NOI/cost yield is 12%.

The 14.4% gross screen is neither the 12% income screen nor a dated unlevered cash return. Reconcile actual work, leasing, downtime, operating costs, collections and later capital payments before forming the cash path. A stated annual premium does not need another multiplication by twelve; that conversion applies to a matching monthly amount. A cost denominator must be positive and must cover the same project and unit population as the numerator.

Cost Inputs and Related Owners

Use CRE Valuation Methodologies for cost/commitment/funding boundaries, Lease Execution Costs and Allowances for lease-work and commission inputs, and Replacement Reserve Funding for account contributions and actual replacement payments. Rent or downtime already reflected in a path is not another automatic cash deduction.

Multifamily Value-Add Renovation owns the apartment thesis and premium-evidence application. Multifamily CapEx Budgeting, Office CapEx Risk Analysis, CRE CapEx Risk Analysis and Industrial CapEx and Physical Risk Underwriting supply their work and sector contexts. CRE Return Metrics and KPIs retains payback, IRR and the other defined return measures; this project-cash method supplies compatible inputs rather than replacing those definitions.
