Knoxville DSCR Rental Loans: Underwriting a Market Split Between Long-Term Doors and the Smokies

Knoxville is one of the few mid-size markets where an investor can run two completely different rental strategies inside a forty-five minute drive, and where the DSCR file looks nothing alike depending on which one you pick. Buy a 3/2 in Fountain City and you are underwriting a $1,650 lease against a $232,000 purchase price. Drive east on I-40 toward the Sevier County line and you are underwriting a cabin at $78,000 of gross annual revenue with a 38% expense load and a lender that wants twelve months of platform history before it will look at you.

Both are DSCR loans. They are not priced the same, sized the same, or reserved the same, and investors who treat the Knoxville MSA as one market get surprised at underwriting. Here is what actually happens on each file.

The long-term rental math in Knox County

Start with the conventional side, because it is where most first Knoxville deals get done.

Median sale prices across Knox County have settled in the $310,000 range MSA-wide, but the investor-relevant submarkets sit well below that. North Knoxville around Fountain City and Inskip, the Burlington and Chilhowee Park corridors east of downtown, Lonsdale, and the older Powell inventory all transact between $185,000 and $265,000 for three-bedroom single-family stock. Rents on that same product run $1,450 to $1,800 depending on condition and school assignment.

Run the coverage ratio on a representative file. A $235,000 purchase at 75% LTV is a $176,250 loan. At 7.25% on a 30-year amortizing DSCR note, principal and interest is roughly $1,202. Knox County property taxes are the quiet advantage here — the effective rate on residential property runs near 0.56%, among the lowest of any metro in the Southeast, which puts annual taxes on that property around $1,316, or $110 a month. Landlord insurance runs $1,500 to $2,100 annually in this part of Tennessee, call it $150 a month. No HOA on most of this stock.

Total PITIA: about $1,462. Against a $1,650 lease that is a 1.13 DSCR. Against $1,750 it is 1.20. That clears the ratio threshold at nearly every lender on the lender directory without a buydown, and it clears comfortably enough that you retain pricing tiers rather than getting pushed into the sub-1.0 programs.

That tax rate matters more than investors expect. The same $1,650 rent in a 1.4% effective-tax market carries roughly $165 a month more in escrow, which drops the ratio from 1.13 to 1.01 and moves you a full pricing tier. If you are comparing Knoxville against other options on the Tennessee state page or against a higher-tax Midwest market, the carrying-cost differential is often worth more than the headline rent-to-price spread suggests. Run both through the DSCR calculators before you assume the higher cap rate market wins.

Why the University of Tennessee submarket is its own underwriting problem

The blocks around campus — Fort Sanders, parts of Cumberland Avenue, the streets feeding into the strip — produce very high gross rents on a per-room basis and very inconsistent DSCR treatment.

A five-bedroom house leased by the room at $650 per bed is $3,250 a month against a property that might sell for $340,000. That is a gross yield most Knox County long-term product cannot touch. The problem is that lenders do not all count it the same way. Some will underwrite the aggregate of individual room leases. Others require a single master lease on the property and will only count what that document says. A few treat rent-by-the-room as a co-living product and route the file to a specialty program with a 70% LTV cap and a 1.15 minimum ratio rather than 1.0.

Summer vacancy is the other issue. If your leases run nine months and the appraiser's 1007 rent schedule reflects a twelve-month market rent of $2,200 for the house as a single unit, an underwriter may use the lower of actual or market — and $2,200 against a $340,000 property at 75% LTV is a 0.98 ratio, not the 1.4 your room-by-room pro forma showed. Ask the question before you are under contract, not after. The documentation standards mirror what we covered in the co-living and rent-by-the-room underwriting guide.

The Sevier County short-term rental corridor

Now the other Knoxville. Gatlinburg, Pigeon Forge and Sevierville sit 30 to 45 minutes from downtown Knoxville, and they form one of the highest-revenue cabin markets in the country. Investors frequently live in or buy out of Knoxville and operate in Sevier County, which makes the two markets a single investment thesis with two entirely separate lending treatments.

Cabin pricing runs wide. A two-bedroom cabin with a hot tub and a partial mountain view trades in the $410,000 to $520,000 range and typically produces $62,000 to $84,000 of gross annual revenue. A larger four to six bedroom lodge-style property at $850,000 to $1.3 million can generate $140,000 to $210,000 gross. Those are real numbers, and they are also gross numbers — which is exactly where DSCR underwriting on these files gets interesting.

Lenders do not underwrite short-term rental income the way they underwrite a lease. Most take trailing twelve-month gross revenue from an AirDNA report or a platform statement, then apply an expense haircut of 25% to 40% before the number reaches the coverage calculation. On a $78,000 gross cabin with a 35% haircut, you are underwriting $50,700 of annual income, or $4,225 a month. Against a $455,000 purchase at 70% LTV — and most lenders cap STR at 70% to 75%, not 80% — the loan is $318,500, P&I at 7.75% is about $2,282, Sevier County taxes at roughly 0.42% effective add $159, and STR-rated insurance runs $400 to $550 a month rather than the $150 you pay on a Knoxville long-term door. Total carry near $2,790 against $4,225 of haircut income is a 1.51 ratio. Strong file.

Without twelve months of history, a market-projection file on the same cabin gets a deeper haircut, 5 to 10 points more of LTV reduction, and a higher reserve requirement — often nine to twelve months of PITIA instead of six. We broke the full mechanics down in the Pigeon Forge STR deep dive, and the property-level revenue detail sits on the Pigeon Forge metro page. The broader program rules are on the short-term rental financing hub.

Tennessee-specific items that show up at closing

A few things catch out-of-state investors.

Tennessee has no state income tax on wages, which is a frequent reason investors form their holding entity here, but it does levy a franchise and excise tax on LLCs and corporations — 6.5% excise on net earnings plus a 0.25% franchise tax on the greater of net worth or real property value. A single-member LLC holding one rental can often claim the FONCE exemption if it is family-owned and at least 66.67% of gross receipts come from passive investment income, but this is a real filing obligation, not a formality. Confirm it with a Tennessee CPA before you assume the entity is free to hold.

Tennessee is also a deed of trust state with non-judicial foreclosure, which lenders price favorably relative to judicial states — part of why Tennessee pricing tends to run a few basis points inside comparable Midwest markets.

Closing costs are moderate. Expect the state recordation tax at $0.37 per $100 of the indebtedness, roughly $652 on that $176,250 loan, plus title and lender fees.

How Knoxville compares to Nashville for a DSCR buyer

This question comes up on every Tennessee call. Nashville has better appreciation history and a deeper rental pool; Knoxville has materially better day-one coverage ratios. A Nashville three-bedroom at $465,000 renting for $2,450 produces a ratio near 0.92 at 75% LTV before you buy points — a file that needs a rate buydown or a larger down payment to clear. The same coverage in Knoxville arrives without engineering. If you are optimizing for cash flow and financeability rather than equity growth, Knoxville is the easier file, and the Nashville deep dive lays out the other side of that trade.

For investors newer to business-purpose lending, the qualifying framework itself is worth a pass through how DSCR loans work before you underwrite a specific Knoxville address — the ratio is only one of four gates, and reserves and entity structure trip up more Tennessee files than coverage does. Current inventory and submarket detail sit on the Knoxville metro page.
