What this means for you Summary
Snapshot
- This is a 4 × 2-bed/1.0-bath units multifamily listed at $584k. Condition is rated good.
Deal economics
- At list price, monthly cash flow is $960 ($12k/yr) — positive. Per door: $240/mo.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($6k rent vs $584k).
- Cap rate 8.4% vs local median 2.4% in Madison — 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 84/100 on livability (#39 in WI, #819 nationally) — a professional / high-income tenant draw. Strengths: commute A+, employment A+, housing A+.
- Madison Metropolitan School District (urban): math 35% / reading 40% proficiency, ranked #193 of 342 in WI (top 56%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
- Zoned schools: Emerson Elementary (math 54% / reading 44%, grade D, #257 of 1,041 statewide, top 30%, 351 students, 57% FRL); East High (math 32% / reading 42%, grade F, #123 of 483 statewide, top 28%, 1,649 students, 55% FRL).
- Market conditions: Rents rising (+1.1%/yr); 140 active listings in the ZIP; 5,519 units permitted in Dane County in 2024 (3,978 in 5+ unit buildings).
- At $6,394/mo this rent would consume 104% of the median local household income ($74k/yr) (locally 2064% 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 $4k of loan paydown is wiped out by about $18k of value loss. Plan a longer hold.
- Dane County population projected at +35% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
Negotiation context
- Only 10 days on market — expect competitive offers; lowballing is unlikely to land.
Risks & watch-outs
- Watch-outs: flood insurance adds $56/mo; built in 1953 — expect roof / HVAC / electrical / plumbing capex.
- Climate carrying-cost: severe flood risk — expect insurance premiums to compound above CPI over the hold.
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 1953 — 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?
- 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.
