Multifamily Feasibility Study, Georgia — An Agency / Conventional Worked Case
This is how our independent feasibility study company and apartment feasibility consultant team analyzed a new-build, market-rate garden/mid-rise community underwritten to a bank construction loan with an agency permanent takeout, from primary-market absorption and capture through the debt-service coverage the permanent lender must document. It is an anonymized, composite worked example of the methodology — the parties, parcel, and figures are composited rather than a specific named borrower or address — set in a fast-growing suburb of metro Atlanta.
A new apartment community on a growing Atlanta suburban edge.
A developer came to our feasibility study company with a ground-up, market-rate apartment project and a two-stage capital plan — a bank construction loan taken out by a Fannie Mae or Freddie Mac agency permanent loan at stabilization — that needed the projected cash flow independently tested before either lender would commit. The subject is roughly 10 acres in a fast-growing outer-ring suburb of metro Atlanta, a market that holds more than half of Georgia's population and where several exurban counties rank among the fastest-growing in the country.1 The build program is about 200 units of garden and low mid-rise product at roughly 20 units per acre, an average unit near 950 square feet, and a Class A amenity set aimed at the renter-by-choice household the corridor is adding.
Because the agencies and their seller-servicers require a market study rather than a feasibility study — a demand-and-supply analysis that informs the lender's own underwriting — the operative question is not “what is the land worth” but “will this specific community lease at the assumed effective rent, on the assumed pace, and then cover its permanent debt.”7 On a newly built, still-leasing asset the permanent loan is sized by debt-service coverage before loan-to-value, so absorption accuracy and effective rent, not headline value, decide the credit.6 Our scope was the independent absorption, capture, competition, and coverage analysis that supports both the construction facility and the agency takeout.
Absorption, capture, and fair share in the primary market area.
The demand read starts with qualified renter households, not a vacancy figure applied to a county. We drew a primary market area (PMA) on drive time and competitive geography, then sized the annual rental demand at the subject's rent point and tested what the community must capture to lease.
Absorption is derived across the four layers a reviewer expects: demand drivers, the supply pipeline, capture, and the resulting monthly lease-up schedule.7 On the demand side, the PMA is a fast-growing slice of exurban Atlanta where household formation is led by in-migration and job growth rather than a single employer; metro Atlanta added residents in every core county in 2024–25, led by Fulton and Gwinnett, and the northern exurbs grew far faster in percentage terms, with counties such as Dawson up 6.4 percent and Jackson up 5.8 percent since 2020.110 Netting income- and size-qualified renter households against the units already available, the model supports roughly 1,150 net qualified renter households a year in the PMA at the subject's $1,500–$2,000 effective-rent band.
Two ratios then discipline the forecast. Capture rate is subject units divided by qualified annual demand: 200 units against about 1,150 qualified households is a roughly 17 percent capture over the lease-up window — comfortably inside the range a market-rate garden deal can defend, and the ratio an over-broad PMA would quietly understate by inflating the demand denominator.7 Fair share is the subject's slice of competitive units leasing in the same window: 200 of about 630 competing units, or roughly a 32 percent fair share, against which the subject's newer product and amenity position argue for a modest premium. At a benchmarked pace near 18 units per month — within the 12-to-25-unit band typical of stabilized garden and mid-rise product — the community reaches stabilized occupancy in roughly twelve to fourteen months, a lease-up under eighteen months that signals healthy, not aggressive, demand.7
| Demand driver | Basis | Supported figure |
|---|---|---|
| PMA net qualified renter demand | Household formation, in-migration, income- and size-qualified at $1,500–$2,000/mo1 | ≈ 1,150 households/yr |
| Competitive units in lease-up window | Subject 200 + ~430 competing units delivering/leasing | ≈ 630 units |
| Required capture rate | 200 subject units ÷ ~1,150 qualified demand7 | ≈ 17% |
| Subject fair share | 200 subject units ÷ ~630 competitive units | ≈ 32% |
| Absorption pace | ~18 units/mo (12–25/mo benchmark band)7 | ≈ 12–14 mo to stabilization |
Capture and absorption logic follows NCHMA demand-and-capture methodology and the Georgia DCA market-study convention; see source 7. Household growth grounded in Census and ARC data (sources 1, 10). Figures are illustrative of the engagement type.
The competitive set, and the pipeline delivering into lease-up.
The correct competitive denominator is not today's standing inventory — it is the units that will be leasing during the subject's own lease-up window. We field-verified the comparable set and scanned the permitted and under-construction pipeline so the capture forecast is not quietly overstated by supply the trailing data cannot yet see.
| Community | Type / vintage | Units | Eff. rent | Status | Read |
|---|---|---|---|---|---|
| Comp A | Class A garden, 2023 | 312 | $1,690 | Stabilized ~93% | Direct comp; concessions burning off |
| Comp B | Class A mid-rise, 2024 | 268 | $1,815 | Leasing ~78% | In lease-up; ~6 weeks free |
| Comp C | Class B garden, 2016 | 240 | $1,480 | Stabilized ~95% | Older; price-led alternative |
| Comp D | Class A garden (pipeline) | 300 | ~$1,780 proj. | 2027 delivery | Delivers mid lease-up; key risk |
| Comp E | BTR townhome, 2025 | 140 | $2,050 | Leasing | Adjacent product; partial overlap |
| Comp F | Class A wrap, 2022 | 285 | $1,725 | Stabilized ~94% | Sets the achievable rent ceiling |
Comparable set field-verified for the engagement; anonymized. Announced and permitted supply was scanned, not just the standing set, consistent with NCHMA field-verification requirements. Effective rents net of in-place concessions.
The set brackets the subject cleanly. Comp F, a stabilized 2022 Class A community at a $1,725 effective rent, establishes the achievable rent ceiling; Comp C, an older Class B garden at $1,480, marks the price-led floor. The subject's underwritten $1,750 stabilized effective rent sits between the newest stabilized comp and the still-leasing mid-rise, a defensible position for newer product rather than an optimistic reach above the market. The two entries that matter most to the credit are the ones still delivering: Comp B, absorbing its final units on roughly six weeks of free rent, and Comp D, a 300-unit community permitted to deliver squarely into the subject's lease-up window.5 A study that used only the standing, stabilized set would understate the competitive supply the subject actually faces and overstate its capture — one of the most common ways an apartment absorption forecast fails review. Here the pipeline is included in the fair-share denominator, and the pace is graded accordingly.
Georgia backdrop: metro Atlanta is digesting a record cycle.
The state context is a tailwind for a well-located suburban community, but only against a named, current supply read. Metro Atlanta was one of the most oversupplied apartment markets of the last cycle, and the story now is digestion toward balance rather than either the 2023 crash or an uncritical 2026 rebound.
A record of roughly 21,200 units delivered in metro Atlanta in 2023 drove vacancy to about 11.1 percent and pushed rents down.4 Digestion has been rapid: deliveries fell more than 50 percent from the Q3 2024 peak, the pipeline stood near 16,800 units at year-end 2025, and stabilized vacancy compressed to roughly 5.9 to 6.1 percent.2 Marcus & Millichap projects 5.2 percent vacancy and a 4.1 percent rent gain to about $1,650 per month for 2026, ranking Atlanta second among major U.S. metros for rent growth after two years of declines.3 Vendor reads diverge sharply — an inventory-basis measure still put vacancy near 11.1 percent in early 2026 — and that spread must be reconciled to a named data source before it drives a pro forma, because importing either the crash or the rebound as a static baseline is the core Atlanta failure mode.4 The subject's underwriting therefore leans on the stabilized-basis vacancy near 6 percent, an effective rent net of concessions, and a graded lease-up rather than the peak-optimism rent gain.
Two structural forces frame the medium term. Concessions are near a twelve-year high nationally — about 16.9 percent of stabilized units offering discounts averaging 10.9 percent, the equivalent of nearly six weeks free — so a revenue model built on posted rather than effective rent overstates year-one income before vacancy is even applied.5 Offsetting that, the delivery pipeline is falling fast while demand has re-engaged, which is why a supply-heavy metro is expected to tighten through 2026–27. Georgia's cost and tax backdrop helps a new owner: the state moved to a flat 4.99 percent income tax for 2026, carries no local income taxes, and holds an effective property-tax rate around 0.79 to 0.92 percent, though buyers should underwrite to the reassessed basis rather than the developer's construction-period bill.12 Two risks belong in the expense line explicitly: rising insurance — one Atlanta portfolio reported a 35 percent premium increase after Hurricane Helene's catastrophic inland damage in 2024 — and Georgia Power's data-center load growth, a demand tailwind for the region and a utility-cost risk at once.1113
Why the site captures the corridor's renter growth.
Household growth, income, and employment access all point the same direction, and the site's position converts that demand into leases at the underwritten rent.
The PMA carries a median household income comfortably above the level at which the subject's $1,750 effective rent stays within a healthy rent-to-income band, and a renter base broadened by the for-sale affordability gap that keeps renter-by-choice households in apartments longer. The exurban growth rate means trailing Census counts understate the captive base — a common distortion a careful study corrects for rather than extrapolates — while the surrounding county mix warns against the opposite error of importing metro-wide averages onto a specific submarket, since Atlanta submarkets have posted opposite rent movements within the same quarter.13
Location does the rest. The site sits on a growth corridor with highway access to the metro's job cores, a well-regarded school district that supports family-renter demand, and adjacent retail that shortens the amenity gap a new community must otherwise build itself. The renter-by-choice positioning — Class A finishes, a competitive amenity deck, and unit sizes near 950 square feet — targets exactly the household the corridor is adding, and lets the community hold effective rent between the newest stabilized comp and the still-leasing mid-rise rather than competing on price with the older Class B stock. That positioning is what supports the capture and fair-share assumptions the demand section carries.
Bank construction loan, agency permanent takeout.
Total development cost lands at $41.0 million, about $205,000 per unit. Market-rate apartments are not SBA-eligible — the programs require owner-occupancy — so the project routes through the standard apartment stack: a bank construction loan during the build and lease-up, taken out by a Fannie Mae or Freddie Mac agency permanent loan once the community stabilizes.6
| Cost component | Amount |
|---|---|
| Land (~10 acres) | $4.10M |
| Site work, infrastructure & utilities | $3.90M |
| Building hard costs (shell & interiors, 200 units) | $23.60M |
| Amenities, parking & site improvements | $2.40M |
| Architecture, engineering & soft costs | $2.60M |
| Financing costs & construction-period interest reserve | $2.20M |
| Marketing, lease-up & operating-deficit reserve | $1.10M |
| Developer fee & contingency | $1.10M |
| Total development cost | $41.00M |
| Item | Figure |
|---|---|
| Bank construction loan (65% LTC) | $26.65M |
| Sponsor / JV equity (35% LTC) | $14.35M |
| Stabilized value (NOI $2.50M ÷ 5.25% cap) | ≈ $47.6M |
| Agency perm ceiling — LTV test (~65%) | ≈ $30.9M |
| Agency perm ceiling — DSCR test (1.30x) | ≈ $26.7M ← binds |
| Agency permanent loan (~6.0% / 30-yr amort, 10-yr term) | $26.7M |
| Annual permanent debt service (7.19% constant) | ≈ $1.92M |
Agency terms and coverage conventions per Fannie Mae DUS / Freddie Mac Optigo practice and the CBRE Q4 2025 underwriting survey; ~1.25x DSCR floor and up to ~80% LTV ceiling by program, sized to the more restrictive test. See sources 6 and 8.
The decisive number is which test binds. At a stabilized value near $47.6 million, the agency's loan-to-value ceiling would allow roughly $30.9 million, but the 1.30x coverage the loan is underwritten to on $2.50 million of stabilized net operating income caps proceeds at about $26.7 million — a realized loan-to-value near 56 percent, well below the program ceiling.6 This is the coverage-constrained takeout that defines newly built lease-up assets in a higher-rate environment: the permanent loan is sized by debt service, not leverage, so the market study's absorption and effective-rent conclusions, not the appraised value, decide how much debt the asset can carry. Here the $26.7 million takeout cleanly retires the $26.65 million construction balance, so the coverage constraint does not open a funding gap — but it is the first thing we stress, because a softer rent or a slower lease-up would size the takeout below the construction loan and force additional equity at refinance. The agency loan is also assumable, which supports a later sale to a buyer who inherits the in-place financing.
Feasible and financeable, on coverage the agency can document.
The stabilized model builds effective gross income from lease-up to occupancy, nets a new-construction expense load, and carries the debt-service coverage across the absorption ramp to a stabilized 1.30x — above the agency floor.
| Line | Basis | Amount |
|---|---|---|
| Gross potential rent | 200 units × ~$1,750/mo effective × 123 | ≈ $4.20M |
| Other income | Parking, fees, and utility reimbursement (~7% of GPR) | ≈ $0.29M |
| Less vacancy, concession & credit loss | ~6.9% at stabilization (stabilized-basis)5 | ≈ ($0.31M) |
| Effective gross income (EGI) | Collected income at stabilization | ≈ $4.18M |
| Operating expenses | Taxes (reassessed basis), insurance, payroll, R&M, utilities, mgmt & G&A (~40% of EGI)9 | ≈ ($1.68M) |
| Net operating income (NOI) | EGI less operating expense (~60% margin) | ≈ $2.50M |
Expense ratio near 40 percent of EGI reflects new-construction efficiency and Georgia's moderate property-tax rate, underwritten to the reassessed basis and an elevated post-Helene insurance line; the national apartment range runs 38–55 percent. See sources 9, 11, 12.
| Year | Stage | NOI | Occupancy | DSCR |
|---|---|---|---|---|
| Year 1 | Lease-up (interest reserve) | ~$1.63M | ~58% avg | 0.85 |
| Year 2 | Ramp; concessions burning off | ~$2.21M | ~90% avg | 1.15 |
| Year 3 | Stabilized | ~$2.50M | ~94% | 1.30 |
DSCR computed as NOI divided by the permanent annual debt service. Year 1 sits below 1.0 by design and is carried by the construction facility's interest reserve during lease-up; the permanent loan is measured at stabilization. See sources 6 and 8.
The stabilized 1.30x coverage is the figure the agency 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 0.85x is intentionally below 1.0 — it is the lease-up year — which is exactly why the construction facility carries an interest and operating-deficit reserve: the reserve funds the ramp, and permanent, fully amortizing coverage is measured only once the community reaches stabilized occupancy. Modeling stabilized rents in Year 1, or best-in-class absorption from day one, is one of the most common ways an apartment pro forma fails review; the ramp here is deliberately graded to a benchmarked pace and an effective rent that burns off concessions over the first two years.5
On the equity side, the $14.35 million injection earns modest levered cash flow during stabilization — on the order of $0.5 million a year once the permanent loan is in place and growing with rent — with the return weighted, as development returns are, toward the value created between cost and stabilized value. Capitalizing the stabilized NOI near $2.50 million at a mid-5 percent rate implies a value around $47.6 million against a $41.0 million cost, a development margin the market study exists to protect.6 On a build-to-stabilization hold with a sale around Year 5 — underwriting roughly 3.5 percent annual rent growth, a 5.0 percent exit capitalization rate, and 2 percent selling costs — the net sale proceeds after retiring the amortized agency balance return roughly $27 million to equity, and the blended result is an illustrative levered equity IRR of about 15 percent.3 Holding rent growth flat to the metro forecast and widening the exit cap, rather than assuming compression, keeps the return defensible rather than optimistic.
Verdict: financially feasible and financeable. On independently derived absorption, a stabilized 1.30x DSCR that clears the agency floor, and a ~15% illustrative levered equity IRR, the projections support both the bank construction loan and the agency permanent takeout.
Independent absorption, capture, competition, and coverage stress.
The engagement was scoped the way an agency seller-servicer and a construction lender read it, to the conventional and institutional standard and to NCHMA Model Content Standards Version 3.1, the recognized framework for rental-housing market studies.7 As an independent apartment 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. We drew the primary market area on drive time and competitive geography rather than a county line, field-verified the comparable set, and forecast absorption on qualified demand, a benchmarked pace, and a capture rate the PMA can support, at an effective rent net of concessions rather than a posted asking rent.
The coverage analysis was then stress-tested against the two variables a lease-up asset is most exposed to — absorption pace and effective rent — to confirm the credit still holds when the ramp slows or concessions deepen, and specifically to test whether the coverage-constrained agency takeout still retires the construction loan under a softer rent. One scope boundary is worth stating plainly: as the feasibility consultant, we prepare the market study and the pro forma coverage analysis; the appraisal that supports the agency's loan-to-value test is a separate USPAP engagement, and where the deal touches Georgia-specific factors — reassessed property taxes, post-Helene insurance, and utility cost — those flow through the expense line explicitly. That combination is what lets both lenders rely on the file.
