Investing in Portland, TN — Market Analysis
Portland is one of the lower-basis entry points in Tennessee, with a median home price around $330,000. Portland is a suburban growth market, which typically means single-family stock, longer average tenancies, school-district-driven demand, and lower turnover cost than urban infill. Suburban DSCR deals tend to underwrite cleanly because the rent comps are homogeneous.
Buying a rental property in Portland on a DSCR loan means putting a minimum of $66,000 down (20% of purchase price), leaving a loan amount of $264,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $1,846 per month. Add Sumner County property taxes of roughly $187/month and landlord insurance of about $132/month, and your all-in PITIA lands near $2,165/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in Portland should generate roughly $1,775/month in gross rent. Against a PITIA of $2,165, that produces an estimated DSCR ratio of 0.82x. That is well below the 1.0 threshold on a long-term lease, which is typical for a market at this price point. Financing here generally works one of three ways — a larger down payment, a no-ratio DSCR product, or qualifying on short-term rental revenue instead of long-term rent.
Two Tennessee-specific items to build into your model: Tennessee assesses residential and rental property at 25% of appraised value and has no state income tax on rents, but Sevier and Blount county short-term rental permitting is county-specific — confirm the property's zoning classification before you underwrite nightly revenue. In Portland specifically, effective property tax on investment property runs around 0.68% of value annually — about $2,244 a year at the median price — and landlord insurance near $1,584 a year.
On return metrics, Portland pencils to an estimated cap rate of 4.00% using a 62% NOI margin, and a gross rent multiplier of 15.5. Monthly cash flow on a long-term lease at 20% down is estimated at $390 negative. Negative cash flow at 20% down is common in appreciation-led markets; investors here typically increase the down payment, buy below median, add a unit, or run the property short-term to close the gap.
