Multifamily Feasibility Study, North Carolina — An Agency / Conventional Worked Case
This is how our independent feasibility study company and apartment feasibility consultant team analyzed a new-build, market-rate apartment community underwritten to a conventional bank construction loan and an agency permanent takeout, from trade-area rental demand and absorption through the debt-service coverage a lender must document. It is an anonymized, composite worked example of the methodology — not a specific client deal — set on a roughly 200-unit mid-rise in a high-growth suburban submarket of the Charlotte–Raleigh growth corridor.
A new mid-rise on a high-growth North Carolina arterial.
A developer came to our feasibility study company with a ground-up, market-rate apartment project and two lenders who needed the projected cash flow independently tested: a bank construction lender sizing the interest reserve, and an agency permanent lender who would take out the construction loan at stabilization. The subject is a roughly 200-unit, four-to-five story mid-rise on an infill suburban parcel in a high-growth submarket of the Charlotte–Raleigh growth corridor, with structured parking, a Class-A amenity set, and a studio-through-two-bedroom unit mix aimed at renter-by-choice households in the trade area.
Because market-rate multifamily is judged on whether it will lease and cover its debt, the lenders' question is not simply “what is the dirt worth” but “how fast will this specific community absorb, at what effective rent, and will the stabilized net operating income size a permanent loan large enough to retire the construction balance.”11 In agency and conventional lending the deliverable is a market study — a demand and supply analysis that informs the lender's own underwriting — wrapped inside a feasibility study that adds the site-specific pro forma and the coverage conclusion. Our scope as the independent feasibility consultant was exactly that: demand, absorption, capture, competition, and the debt-service coverage that carries the credit from groundbreaking through permanent financing.
Absorption, capture, and fair share.
The demand read starts with income-qualified renter households in a tightly drawn primary market area, not a metro average applied to a submarket. North Carolina added roughly 145,907 residents in the year to July 2025, a 1.3 percent gain that ranked third nationally in growth rate and led every state in net domestic migration — the household formation a new community leases into.
Absorption is derived across four layers, in the order a reviewer reads them. Demand drivers — employment, household formation, in-migration, and income by tier — establish annual rental demand at the subject's rent point; the supply pipeline sets the competitive constraint, counting the units delivering during the lease-up window rather than today's snapshot; capture-rate analysis allocates that demand against the subject and the competing set; and the resulting monthly lease-up schedule sizes the interest and working-capital reserve.11 On a roughly 15-minute drive-time primary market area, income- and size-qualified demand at the subject's effective rent supports about 1,100 renter households a year. Against that base, 200 units is roughly an 18 percent capture rate — meaningful but well inside the over-broad-market-area red flag that inflates the demand denominator and understates capture.11 The supported absorption pace is about 16 units a month, a twelve-to-thirteen-month lease-up that sits squarely inside the twelve-to-twenty-five-unit band NCHMA benchmarks for stabilized mid-rise product: fast enough to avoid the oversupply-or-mispricing signal beyond eighteen months, disciplined enough to avoid the aggressive-assumption signal under six.
| Demand driver | Basis | Supported figure |
|---|---|---|
| Primary market area | ~15-minute drive-time ring around the site | Tightly drawn PMA |
| Income-qualified renter demand | Household formation + in-migration + turnover at the subject's rent tier1 | ≈ 1,100 households/yr |
| Competitive units into lease-up window | Subject plus comparable lease-ups delivering in the PMA11 | ≈ 560 units |
| Subject capture rate | 200 units ÷ ~1,100 qualified households | ≈ 18% |
| Supported absorption | ~16 units/month, inside the 12–25 unit NCHMA band11 | ≈ 12–13 month lease-up |
Demand and capture logic grounded in NCHMA demand and capture-rate methodology and North Carolina migration data; see sources 1 and 11. Figures are illustrative of the engagement type.
A record delivery cycle, now thinning into the lease-up window.
Five stabilized or leasing communities compete within three miles, and the correct competitive denominator is not today's standing set but the units delivering while the subject leases. The decisive fact is timing: Charlotte and the Triangle crested a record supply wave, and starts have since collapsed, so the pipeline arriving into this community's lease-up window is shrinking rather than growing.
| Community | Vintage / class | Units | Distance | Read |
|---|---|---|---|---|
| Community A | 2023 / Class A | 320 | 1.2 mi | Stabilized ~94%; 4–6 weeks concession |
| Community B | 2024 / Class A | 288 | 2.0 mi | Mid lease-up; ~8 weeks concession |
| Community C | 2019 / Class B+ | 240 | 1.8 mi | Stabilized ~96%; value alternative |
| Community D | 2025 / Class A | 210 | 2.6 mi | Delivers into the subject's window |
| Community E | 2016 / Class B | 264 | 3.0 mi | Stabilized ~95%; older amenity set |
Competitive set field-verified for the engagement, consistent with NCHMA comparable-verification practice; anonymized. Announced and permitted supply was scanned, not just the standing set. See source 11.
Only two Class-A communities are still leasing within the ring, and the read on effective rent matters more than the posted number: in the softest phase of the cycle, concessions ran on roughly 27 percent of Charlotte units, so a revenue model built on asking rents rather than effective rents overstates year-one income by the concession value plus loss-to-lease.25 The favorable structural fact is the pipeline turn. Charlotte developers delivered a record 16,700-plus units in 2024, more than double the 2015–2019 average, but construction starts have since fallen roughly 40 percent, and in the Triangle deliveries were down 63 percent year over year in the first quarter of 2026.23 A rigorous study does not stop at the standing set; it counts what delivers during lease-up, and here that denominator is contracting sharply — the community leases into a thinning field rather than splitting demand with a wave of new supply.
North Carolina: a record cycle digesting into an undersupplied window.
The state backdrop is a tailwind for a well-located new community, tempered by the tail of the supply wave and by an operating-expense load that must be stressed. North Carolina is one of the fastest-growing large states in the country, and its two big apartment metros are digesting a record delivery cycle just as the forward pipeline collapses.
Charlotte is a signature Sun Belt oversupply-then-inflection story: asking rents were down 1.3 percent year over year with vacancy near 8.2 percent in the softest quarter, while the Triangle tracked 7.7 to 8.0 percent vacancy with rents easing about 0.7 percent.234 Those are digesting markets, not distressed ones, and the national frame explains why they inflect: apartment completions reached roughly 608,000 units in 2024, the most since 1986, then began falling, while construction starts collapsed about 60 percent from the 2022 peak. Because completions lag starts by eighteen to twenty-four months, the 2026–2027 delivery window a new community leases into is guaranteed thin.67 A study that blends a statewide or metro average across submarkets moving in opposite directions misprices the deal; this one is built to the subject's submarket and its lease-up window.
Two offsetting realities discipline the model. First, cost: per-unit trade pricing near $208,000 sits well below the cost to build, which runs $300,000 per unit or more in high-cost submarkets, so the feasibility test turns on whether stabilized cash flow supports a leveraged cost basis rather than on optimistic rent growth — and that same replacement-cost gap puts a floor under existing values.9 Second, operating expense: North Carolina reassesses property taxes toward the completed project's basis, and property insurance is rising across the state, with the Department of Insurance settling successive homeowners and dwelling rate increases — both of which we carry in stabilized net operating income rather than lifting a seller's snapshot.15 Cutting the other way, North Carolina's corporate income tax is phasing to zero by 2030 and its flat personal rate sits at 3.99 percent, a pro-growth backdrop for the employment that drives rental demand, and, unlike healthcare, market-rate multifamily is not gated by the state's Certificate-of-Need regime, so supply is set by the market and the capital markets.16
Why the submarket supports the rent.
Household income, employment access, and in-migration all point the same direction, and the site's position converts that demand into leasing velocity.
The primary market area carries a renter-heavy household base with median incomes comfortably above the level at which the subject's effective rent clears a defensible rent-to-income ratio, and a daytime employment draw anchored by the corridor's growth engines — banking, industrial, and advanced-manufacturing employment on the Charlotte side, and technology and life-science employment on the Triangle side. In-migration near the top of the nation means trailing Census counts understate the captive renter base, a common high-growth distortion a careful study corrects for rather than extrapolates.1 The rent-versus-own gap reinforces the demand: with for-sale housing costs elevated, renting remains the lower monthly cost for the target household, keeping renter-by-choice demand deep even as incomes rise.
Location does the rest. The subject occupies an infill suburban parcel with direct arterial access, walkable retail, and a short drive time to the submarket's principal employment nodes — the position that shortens lease-up because it reaches the renter where they already work and shop. Structured parking and a Class-A amenity set let the community hold rent against the newest competitors rather than discount into them, and the field-verified comparable set confirms the subject prices at, not above, achievable effective rents. That combination is why the model credits a twelve-to-thirteen-month absorption rather than an optimistic six-month lease-up, and why the capture rate holds on a tightly drawn market area instead of an inflated one.
Bank construction, taken out to agency permanent debt.
Total development cost lands at $46.0 million, about $230,000 per unit. Market-rate apartments are not SBA-eligible — both the 7(a) and 504 programs require owner-occupancy of at least 51 percent for existing buildings and 60 percent for new construction — so a passive apartment community routes to a conventional bank construction loan and an agency permanent takeout rather than to SBA.13 North Carolina's SBA channel is unusually deep — Live Oak Bank in Wilmington was the number-one national SBA 7(a) lender in fiscal 2025, and the SBA North Carolina District Office in Charlotte covers all 100 counties — but a market-rate apartment community is not an owner-occupied business and does not qualify.14
| Cost component | Amount |
|---|---|
| Land | $5.00M |
| Hard costs (building, site work, structured parking, amenities) | $32.50M |
| Soft costs (design, permits, legal, marketing & lease-up) | $4.50M |
| Financing & capitalized interest reserve | $2.50M |
| Developer fee, contingency & operating reserve | $1.50M |
| Total development cost | $46.00M |
Roughly $230,000 per unit for a suburban North Carolina mid-rise, consistent with a replacement cost well above per-unit trade pricing. See source 9.
| Item | Figure |
|---|---|
| Bank construction loan (65% LTC) | $29.90M |
| Sponsor equity (35%) | $16.10M |
| Agency permanent takeout (stabilized) | $30.80M |
| Permanent terms | ~6.0% fixed / 30-year amortization |
| Permanent sizing tests | min ~1.25x DSCR; ~65% LTV; ~9% debt-yield floor |
| Permanent annual debt service | ≈ $2.22M |
Construction leverage per conventional bank convention; permanent loan sized to the most restrictive of LTV, DSCR, and debt yield. See sources 8, 10, and 11.
The permanent loan is where the study earns its keep, because in a higher-rate environment the agency loan is sized by coverage, not leverage. On a stabilized net operating income of $2.88 million, the 1.25x debt-service-coverage minimum caps the loan near $32.0 million, while the 65 percent loan-to-value ceiling on a roughly $52.4 million stabilized value would allow about $34.0 million — so coverage binds first, and the takeout comes in below the leverage ceiling.8 Proceeds settle at $30.8 million, which holds a 1.30x stabilized DSCR, a debt yield near 9.3 percent, and a loan-to-value close to 59 percent — comfortably inside all three tests. Crucially, because construction leverage was a disciplined 65 percent loan-to-cost ($29.9 million) rather than an aggressive 75-to-80 percent, the coverage-constrained agency takeout still retires the construction balance and returns roughly $0.9 million to equity at refinance. That takeout routes to Fannie Mae or Freddie Mac, whose 2026 purchase caps rose about 20 percent to a combined $176 billion, positioning the agencies as the refinance backstop this construction loan is built toward.10 The DSCR-constrained funding gap that sinks over-levered lease-up deals does not open here — but only because the effective-rent and absorption conclusions the loan is sized against were independently tested rather than assumed.8
Feasible and financeable, on coverage the takeout can document.
The stabilized model builds net operating income from effective rents net of concessions, nets a stressed operating expense load, and carries the coverage up a graded absorption ramp to the 1.30x the agency takeout is sized against.
| Line | Basis | Amount |
|---|---|---|
| Gross potential rent | 200 units at ~$1,958/mo effective | $4,700,000 |
| Other income | Parking, RUBS, fees | $282,000 |
| Gross potential income | Rent plus other income | $4,982,000 |
| Vacancy, concession & credit loss | 7.0% at stabilization5 | ($349,000) |
| Effective gross income | Collections net of loss | $4,633,000 |
| Operating expenses | Taxes (reassessed), insurance, payroll, R&M, management, G&A17 | ($1,753,000) |
| Net operating income (Year 3) | EGI less operating expense | $2,880,000 |
Operating expenses run about 38 percent of effective gross income here, with property taxes reassessed to the completed basis and insurance stressed to the current North Carolina market. See sources 15 and 17.
| Year | Stage | NOI | Debt-service basis | DSCR |
|---|---|---|---|---|
| Year 1 | Lease-up (~55% occupied) | ~$1.75M | Interest reserve bridges | 0.79 |
| Year 2 | Absorption (~88% occupied) | ~$2.55M | Permanent ~$2.22M | 1.15 |
| Year 3 | Stabilized (~93% occupied) | ~$2.88M | Permanent ~$2.22M | 1.30 |
DSCR computed as NOI divided by the period debt-service obligation. See sources 8 and 11 for the ~1.25x agency coverage convention.
The stabilized 1.30x coverage is the figure the agency takeout documents, and it clears the roughly 1.25x floor with headroom.8 By Year 2 the community already covers the permanent debt service at 1.15x. The Year 1 figure of 0.79x is intentionally below 1.0 — it is the lease-up year — which is exactly why the structure carries a capitalized interest reserve: the reserve bridges the ramp, and permanent, fully amortizing coverage is measured once the community reaches its supportable occupancy. Modeling stabilized rents on day one, or asking rents while the market clears on concessions, is one of the most common ways apartment pro formas fail review; the ramp here is deliberately graded and the rents are effective, not posted.5
On the value and equity side, capitalizing the $2.88 million stabilized net operating income at a market rate near 5.5 percent implies a stabilized value around $52.4 million against the $46.0 million cost — a development spread near $6.4 million, or an untrended yield on cost of about 6.3 percent against a going-in cap rate in the low-to-mid five percent range.8 The $16.1 million equity injection earns a modest return of capital at the agency refinance, a stabilized cash-on-cash that builds as concessions burn off, and the balance of the return at a Year-10 exit on net operating income grown at a disciplined pace and capitalized at a rate held at or slightly above going-in. Held to the through-cycle assumptions the study defends — effective rents, a stressed expense load, and a coverage-sized takeout — the blended result is an illustrative levered equity IRR of about 15 percent over a 10-year hold.
Verdict: financially feasible and financeable. On independently derived demand, a twelve-to-thirteen-month absorption, a stabilized 1.30x DSCR, and a ~15% levered equity IRR, the projections support the bank construction loan and the agency permanent takeout.
Independent demand, absorption, capture, and coverage stress.
The engagement was scoped the way a credit committee and an agency reviewer read it. As an independent feasibility consultant, our role is to test the developer's projection against the market, not to restate it — the value of the deliverable is precisely that it carries no stake in the outcome. The market study was prepared to NCHMA Model Content Standards, Version 3.1, with a tightly drawn primary market area, field-verified comparables rather than desktop estimates, income-qualified demand, and a capture rate that is not inflated by an over-broad market area.11 Rents were modeled effective, net of the concessions the market is actually clearing, and the competitive denominator counted the supply delivering into the lease-up window, not just today's standing set.
The coverage analysis was then stress-tested where these deals actually break. We graded the absorption ramp and measured coverage year by year rather than reporting a single stabilized figure, and we sized the agency takeout to the most restrictive of loan-to-value, debt-service coverage, and debt yield to expose the coverage-constrained takeout before it became a refinance surprise.8 Where the credit will take out to agency or HUD debt, the study is built to that standard from the outset — an NCHMA market study for the agencies, or the HUD MAP form set (HUD-92273, 92274, and 92264) for an FHA-insured execution — so the same analysis carries the deal from groundbreaking through permanent financing.12 That combination — independent demand, benchmarked absorption, disciplined capture, and a stressed, coverage-sized takeout — is what lets both lenders rely on the file.
