What this means for you Summary
Snapshot
- This is a 1×3bd/2.0ba + 1×1bd/1.0ba units multifamily listed at $185k.
Deal economics
- At list price, monthly cash flow is $538 ($6k/yr) — positive. Per door: $269/mo.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($2k rent vs $185k).
- Recommended offer: $163k (12.0% below list) — sets the bar for market timing.
- Cap rate 10.1% vs local median 5.0% in Louisville — top-decile yield for the area; either an underpriced asset or a hidden risk that comps aren't pricing in. Stress-test before assuming the spread holds.
Location & tenants
- Location reads 63/100 on livability (#333 in KY) — a middle-class / working-renter tenant base. Strengths: cost of living A+, housing A+; Watch: employment C-, health & safety D+, schools D-.
- Jefferson County (urban): math 19% / reading 35% proficiency, ranked #121 of 165 in KY (top 73%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover.
- Market conditions: Rents rising fast (+6.1%/yr); 77 active listings in the ZIP; 21 comparable units currently listed for rent nearby; rentals at typical pace (median 16d on market — plan ~3-4 weeks tenant-placement turnaround); lower-income renter base — watch delinquency; 2,836 units permitted in Jefferson County in 2024 (1,558 in 5+ unit buildings).
- At $2,276/mo this rent would consume 69% of the median local household income ($40k/yr) (locally 1136% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.
Forward outlook
- Local home prices are declining (-3.0%/yr); year-one equity from $1k of loan paydown is wiped out by about $6k of value loss. Plan a longer hold.
- Jefferson County population projected at +13% by 2050 — modest demand growth; plan on rents tracking national, not racing it.
- At projected returns (-3.0% appreciation + 6.1% rent growth), your $52k cash investment doubles in ~8 years — after that, you're playing with house money.
Negotiation context
- It's been on market 154 days — a 12% lower offer ($163k) is reasonable based on typical stale-listing flexibility.
- 5 sale attempts since 16y ago with the ask held roughly flat each time — persistent listings suggest the price (not the market) is what's stuck; bring a comps-based counter.
- Current owner paid $150k; 23% above their basis — modest negotiation headroom, anchor on the comps not their cost.
Risks & watch-outs
- Watch-outs: flood insurance adds $56/mo; built in 1915 — expect roof / HVAC / electrical / plumbing capex.
- Climate carrying-cost: major flood risk; extreme-heat days projected 7→20/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Questions for the listing agent
- It's been on market 154 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
- 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 1915 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
- What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
- Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
- Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
- Schools are D-rated, which usually means shorter tenancies and higher turnover. Who's the typical renter profile here, and what's been the actual vacancy rate?
- Crime grade is F in this area — have there been break-ins, vandalism, or insurance claims at this property in the last 3 years? What carrier currently insures it and at what premium?
- 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.
