Updated 2026 · Based on median market data for Idaho Falls, ID
Idaho Falls sits in the West with a population of 67,000 growing rapidly at 1.8% annually. The median home costs $310,000 while rents average $1,320/mo, producing an estimated cap rate of 3.44%. Cash flow investing here requires creative strategies like BRRRR or value-add approaches.
Idaho Falls works best for experienced investors with a clear strategy — Section 8, student housing, or deep value-add rehabs. The 3.44% cap rate at median prices is tight, so success depends on buying below market, forcing appreciation through renovation, or accessing above-market rent streams through niche tenant bases.
Target properties priced 15-25% below the $310,000 median — around $248,000 or less. At this price point with $1,320/mo rents, your cap rate improves to roughly 4.7%. Factor in 0.64% property taxes ($1,984/yr), budget 5% of gross rent for maintenance, and underwrite to a 4.5% vacancy rate. On a 20% down conventional loan at 7%, monthly PITI will run approximately $1,915.
Every deal should be evaluated individually using our calculator tools. Median data provides a starting point; actual returns depend on the specific property, financing, and your management approach.
