The quick read: A construction loan for a small Knoxville apartment project is sized on cost and on projected value, funded in inspected draws, and repaid by a permanent loan once the building stabilizes. The local twist is property tax. The Tennessee Comptroller's schedule puts Knox County on a two-year reappraisal cycle, with reappraisals in 2026 and 2028, and Tennessee's certified tax rate law resets the rate to revenue-neutral after each one while leaving new construction out of that calculation. A new building can therefore be revalued soon after it stabilizes, so the tax reserve and the stabilization budget cannot be projected off appraised-value growth alone.
How do construction loans work for a small apartment project in Knoxville?
A construction loan for a small Knoxville apartment project covers part of the total cost, releases money in draws after an inspector confirms the work, and converts to or is repaid by a permanent loan once the building leases, with the lender capping proceeds well below the finished value.
The regulatory ceiling is in the interagency real estate lending guidelines at 12 CFR Part 365, Appendix A: a supervisory loan-to-value limit of 80% for commercial, multifamily and other nonresidential construction, 75% for land development and 65% for raw land. Banks set internal limits below those, and the appendix says loan disbursements should not exceed actual construction outlays. Most lenders also set a loan-to-cost limit, so the loan is the lower of the two tests. Our loan-to-cost glossary entry explains the cost side.
Draws follow a disbursement plan. The FDIC's construction lending examination modules (10/25) ask examiners whether the undisbursed loan balance is sufficient to complete the project, whether inspections happen before draw requests, and whether disbursements follow written inspection reports, lien searches and title updates. Expect your lender to hold back money until each stage is verified, and to stop funding if the remaining budget cannot finish the building.

What does Knoxville's permit data say about apartment project size?
Knoxville's 2025 permit data points to mid-size apartment buildings: the Census Bureau's Building Permits Survey lists 84 buildings of five or more units in the Knoxville metro, holding 2,780 units, about 33.1 units per building, with $530.0 million of reported construction value.
The same 2025 annual file lists 4,969 one-unit buildings, 14 two-unit buildings with 28 units, and 20 three- and four-unit buildings with 78 units. These are permit authorizations for the metro, not completions inside city limits. Dividing reported value by units gives about $190,600 per unit, our arithmetic; permit valuations usually exclude land and soft costs, so treat it as a hard-cost floor rather than a budget.
For a sponsor planning 8 to 40 units, the takeaway is that very few small buildings are being permitted, so leased comparables for a new small building may be thin. Lenders will lean on comparables from older stock and on your pro forma, and they will test both.

How does Knox County's two-year reappraisal change the tax reserve?
Knox County's two-year reappraisal cycle means a new apartment building is likely to be revalued within a year or two of opening, and because Tennessee's certified tax rate is calculated without new construction, the rate rollback that follows a reappraisal does not protect a building whose value jumped from dirt to stabilized.
The Tennessee Comptroller's reappraisal schedule lists Knox County's last reappraisal in 2026, its next in 2028 and a two-year cycle, with reappraisals marked every other year through 2032. The certified tax rate statute, as quoted by the University of Tennessee's County Technical Assistance Service, says that after a general reappraisal each governing body certifies a rate that produces the same revenue as the prior year, exclusive of new construction, improvements and deletions. The Comptroller adds that a property whose value rose more than the average may pay somewhat higher taxes.
Two more rules set the timing. The Comptroller's glossary says Tennessee's assessment date is January 1, so appraised values reflect the property's status on that date, and that residential real property is assessed at 25% of appraised value and commercial and industrial at 40%. Ask the Knox County assessor which class your building will carry before you set the tax line, because the class changes the assessed value by more than half.
How should you budget property taxes during lease-up in Knoxville?
Budget Knoxville property taxes in three steps, because the January 1 assessment date captures a partly finished building, the 2028 reappraisal may capture the stabilized one, and your permanent lender will underwrite the full stabilized tax line whether or not the bill has caught up.
Illustrative example (our arithmetic, not a quote; tax rate and class are placeholders): a 30-unit building breaks ground in spring 2026 and opens in spring 2027.
- January 1, 2027: the building is partly complete. The assessor values it at, say, $2.4 million appraised.
- January 1, 2028: a reappraisal year under the Comptroller's schedule. The building is leased and appraised at, say, $6.0 million.
- At a placeholder 40% commercial assessment and a placeholder combined rate of $2.00 per $100 of assessed value, the bill moves from about $19,200 to about $48,000.
The second number is the one a permanent lender will use. If your stabilization budget carries the first, the debt service coverage on the takeout will be overstated. Use the assessor's class and the current combined county and city rates for your parcel, and ask the lender for the tax assumption it will apply. A flat rent market makes this matter more: underwrite rent to current leased comparables, not to growth, and let the tax and reserve lines carry the conservatism.

How do Fort Sanders, Old City and Hardin Valley projects differ for a lender?
Fort Sanders, the Old City and Hardin Valley represent three different construction risks in Knoxville, student-adjacent infill, adaptive reuse of older buildings, and suburban ground-up, and each changes which lenders will quote and which permanent loan can take them out when the building stabilizes.
Fort Sanders sits beside the University of Tennessee campus, and a building there may lease largely to students. That matters for the exit: Freddie Mac's Conventional Small term sheet (4/26), which covers predominantly market-rate properties of 5 to 50 units for acquisition or refinance, excludes student properties. Lenders will ask how many leases are by the bed, whether parents guarantee them, and what the rent roll looks like in summer. Plan the takeout before you design the unit mix.
The Old City is a historic warehouse district downtown, where small apartment projects are often conversions. Conversion budgets carry more unknowns behind the walls, so lenders typically want a larger contingency and a contractor with conversion experience. Hardin Valley, in western Knox County, is suburban ground-up territory where site work, utilities and county permitting drive the schedule.
The City of Knoxville also publishes a Middle Housing Redevelopment Program for small-scale housing. Check the program's current documents with the city before assuming any subsidy in your capital stack. For financing on the back end, see our guide to multifamily bridge lenders in Knoxville, and the Tennessee multifamily construction guide for the statewide lender field.
How do you get construction lenders competing for a Knoxville deal?
Construction lenders compete on a Knoxville apartment project when each one sees the same complete package, including plans, a line-item budget, an interest reserve sized to a realistic schedule, a stabilized tax line built on the reappraisal calendar, and the exit, so term sheets differ on leverage and price instead of assumptions.
YieldStack is a commercial mortgage brokerage. Software matches the deal against 20,000+ loan programs and compares the options; human brokers structure the deal, negotiate on the borrower's side and carry it toward closing. YieldStack reports a median first offer in under an hour, from an institutional lender. Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
For a Knoxville build, the package that gets clean quotes covers:
- Site control, zoning confirmation and permit status
- Plans and a line-item hard and soft cost budget with contingency
- Construction schedule and interest reserve sized to it
- Pro forma rents from leased comparables, with student exposure disclosed
- Tax line at the expected stabilized appraised value and assessment class
- Exit plan: permanent loan, agency takeout or sale
- Sponsor resume, financial statement and completed projects
When it is ready, send the Knoxville deal for review. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing. Local context is on the Knoxville market hub.
The bottom line
A Knoxville apartment construction loan is sized under an 80% supervisory value ceiling and funded in inspected draws. Knox County reappraises every two years, and the certified tax rate rollback leaves new construction out, so put the stabilized tax line in the budget from day one and plan the takeout around student exposure.
