What this means for you Summary
Snapshot
- This is a 2 × 2-bed/?-bath units multifamily listed at $265k. Condition is rated average.
Deal economics
- At list price, monthly cash flow is $645 ($8k/yr) — positive. Per door: $323/mo.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($3k rent vs $265k).
Location & tenants
- Location reads 86/100 on livability (#3 in ID, #428 nationally) — a professional / high-income tenant draw. Strengths: amenities A+, cost of living A+, housing A+.
- Idaho Falls District (urban): math 36% / reading 50% proficiency, ranked #54 of 92 in ID (top 59%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
- Market conditions: 2 active listings in the ZIP; 1 comparable units currently listed for rent nearby; 2,253 units permitted in Bonneville County in 2024 (1,051 in 5+ unit buildings).
Forward outlook
- In year one you build about $10k of equity ($2k loan paydown + $8k appreciation (3.0% local appreciation)).
- Bonneville County population projected at +18% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
- At projected returns (3.0% appreciation + 3.0% rent growth), your $74k cash investment doubles in ~4 years — after that, you're playing with house money.
- By year 4, paydown + projected appreciation supports a ~$33k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.
Negotiation context
- Only 6 days on market — expect competitive offers; lowballing is unlikely to land.
Risks & watch-outs
- Watch-outs: built in 1916 — expect roof / HVAC / electrical / plumbing capex.
Questions for the listing agent
- Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
- What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
- Built in 1916 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
- Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
- What's the average days-on-market for RENTAL listings here right now (not sales)? A rising rental-DOM trend means longer vacancies and softer asking-rent achievability than the comps imply.
- What's the recent tenant-quality profile in this submarket — average credit score on applications, eviction rate, late-payment / NSF rate, and stable-employment percentage? A property-management company in the area should have these aggregated.
- How much new apartment / multifamily construction is in the pipeline within 1–3 miles? Heavy new supply (>2% of stock underway) typically softens rents 12–24 months out; light construction supports rent growth.

For passive investors: Depreciation is non-cash, so a rental often shows a tax loss while cash-flowing — sheltering income. Rental losses are passive: they offset passive income freely, and up to $25,000/yr can offset ordinary (W-2) income if you actively participate and your MAGI is under $100k (phasing out to $0 by $150k); unused losses carry forward. On sale, claimed depreciation is recaptured at up to 25%, and gains may owe capital-gains tax (a 1031 exchange can defer both). Figures are a year-1 estimate at your 24.0% rate — not tax advice; consult a CPA.
