Investing in West Yellowstone, MT — Market Analysis
West Yellowstone prices in the middle of the Montana market, with a median home price around $600,000. West Yellowstone is a resort and vacation-rental market. The long-term rent number here rarely tells the real story — the investment case is usually built on nightly revenue, and lenders that accept documented short-term rental income underwrite these deals very differently from lenders that do not.
Buying a rental property in West Yellowstone on a DSCR loan means putting a minimum of $120,000 down (20% of purchase price), leaving a loan amount of $480,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $3,356 per month. Add Gallatin County property taxes of roughly $370/month, landlord insurance of about $290/month, and an HOA/master-association allowance of $180/month, and your all-in PITIA lands near $4,196/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in West Yellowstone should generate roughly $2,050/month in gross rent. Against a PITIA of $4,196, that produces an estimated DSCR ratio of 0.49x. 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.
If you intend to operate the property as a short-term rental, estimated gross nightly revenue in West Yellowstone is around $4,400/month across a full year. Lenders do not credit gross STR revenue dollar-for-dollar — they typically haircut it 25%–30% for vacancy, cleaning, platform fees, and management. Applying a 28% haircut gives an effective $3,168/month, or a DSCR ratio of 0.75x. Even on short-term revenue this is a tight file, so plan on a larger down payment or a no-ratio structure.
Two Montana-specific items to build into your model: Montana has no sales tax and leans hard on property tax, and the state reappraises residential property on a two-year cycle — the last cycle pushed valuations up sharply in Gallatin, Flathead and Missoula counties. Montana also charges a lodging facility use and sales tax on short-term stays that has to come out of nightly revenue before it reaches your DSCR. In West Yellowstone specifically, effective property tax on investment property runs around 0.74% of value annually — about $4,440 a year at the median price — and landlord insurance near $3,480 a year.
On return metrics, West Yellowstone pencils to an estimated cap rate of 2.54% using a 62% NOI margin, and a gross rent multiplier of 24.4. Monthly cash flow on a long-term lease at 20% down is estimated at $2,146 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.
