Top Real Estate Investing Markets for Idaho 2027

Idaho offers a market for nearly every investor strategy, from long-term rentals in Boise and the fast-growing Treasure Valley to lab-anchored leases in Idaho Falls, low entry prices in Twin Falls and vacation rentals on Lake Coeur d'Alene and just outside Yellowstone. Since July 1, 2026, state law has barred Idaho cities and counties from requiring short-term rental permits or capping rentals, which makes Idaho one of the most investor-friendly STR states in the country. Read our full guide to the Top 6 Idaho Markets for Real Estate Investors in 2027.

Idaho State Capitol in Boise, Idaho
Core Market

Boise

Idaho's capital and largest city sits along the Boise River at the foot of the foothills, with state government, Boise State University, two major hospital systems and Micron's headquarters anchoring demand. Micron's memory chip expansion in southeast Boise is expected to support about 17,000 Idaho jobs, and homes here sell in a median of about two weeks. Nightly rentals book year-round at about 69% occupancy, the highest of the six markets, and with prices near $500,000 most investors size the loan around the full monthly payment with a solid down payment.

Caldwell

Caldwell sits on the western edge of the Treasure Valley in Canyon County, about 25 miles west of downtown Boise, home to the College of Idaho and the Sunnyslope wine region. Its population grew about 27% from 2020 to 2025, and at about $400,000 it offers the best rent-to-value ratio of the six markets, with typical rents near $1,736. Newer single-family homes make Caldwell a natural fit for buy-and-hold and BRRRR investors looking for Boise-metro jobs at a discount.

Idaho Falls

Idaho Falls sits on the Snake River in eastern Idaho, home base for Idaho National Laboratory, which employed about 6,400 people as of early 2025, with a riverside greenbelt and easy access to Yellowstone and the Tetons. The steady base of engineers, contractors and federal workers keeps long-term demand reliable, and nightly rental revenue grew about 10% over the past year. Moderate prices near $372,000 help the numbers work, and our guide on how property value and LTV are determined explains how lenders size these loans.

Twin Falls

Twin Falls is the hub of the Magic Valley, on the rim of the Snake River Canyon near Shoshone Falls and the Perrine Bridge, with Chobani's yogurt plant and the region's food processing industry anchoring jobs. It has the lowest home prices of the six markets and one of the least competitive buying environments in the state, giving investors room to negotiate. Nightly rentals here earn AirDNA's top score among the six markets (90/100), and investors who buy and improve older homes can tap cash-out refinances based on documented improvements.

Coeur d'Alene

Coeur d'Alene sits on the north shore of Lake Coeur d'Alene, about 30 miles east of Spokane, with a resort and floating boardwalk downtown, a busy summer lake season and Silver Mountain skiing about 30 minutes away. It combines year-round demand from Spokane-area residents with summer visitors, posting the fastest rent growth of the six markets and nightly rates above $300. Lake-area condos are common here, and our guide to condos and DSCR loans covers what lenders look for.

Island Park

Island Park stretches along US-20 near Island Park Reservoir, the Henrys Fork, Harriman State Park and Upper Mesa Falls, about 20 minutes from Yellowstone's West Entrance. It is Idaho's top vacation rental market, with average STR revenue near $63,590 and nightly rates near $458, the highest of the six markets, fed by summer Yellowstone visitors, fly fishers and winter snowmobilers. Island Park rentals can often qualify on TTM actuals or STR revenue projections, and there is no local STR permit or city lodging tax beyond the state's 8%.
