What this means for you Summary

Snapshot

• This is a 3-bed/2.0-bath single-family listed at $80k.

Deal economics

• At list price, monthly cash flow is $528 ($6k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($1k rent vs $80k).
• Recommended offer: $75k (6.0% below list) — sets the bar for market timing.

Location & tenants

• Location reads: area grade B — affects rentability + tenant quality, not the cash-flow math above.
• Cahokia CUSD 187 (suburban): math 3% / reading 5% proficiency, ranked #864 of 919 in IL (top 94%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover; 85% free/reduced lunch — lower-income household profile, screen leases tightly.
• Zoned schools: Cahokia High School (math 8% / reading 2%, grade F, #614 of 693 statewide, top 95%, 845 students, 0% FRL) — zoned schools average 0% FRL vs 85% district-wide (85 pts lower); this property's tenant base skews higher-income than the district average.
• Market conditions: 153 active listings in the ZIP; 32 comparable units currently listed for rent nearby; rentals at typical pace (median 24d on market — plan ~3-4 weeks tenant-placement turnaround); lower-income renter base — watch delinquency; 783 units permitted in St. Clair County in 2024 (378 in 5+ unit buildings).
• At $1,367/mo this rent would consume 48% of the median local household income ($34k/yr) (locally 729% 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 $552 of loan paydown is wiped out by about $2k of value loss. Plan a longer hold.
• St. Clair County population projected at -23% by 2050 — secular population decline; favor cash flow + early exit over multi-decade hold.
• At projected returns (-3.0% appreciation + 3.0% rent growth), your $22k cash investment doubles in ~5 years — after that, you're playing with house money.

Negotiation context

• It's been on market 62 days — a 6% lower offer ($75k) is reasonable based on typical stale-listing flexibility.

Risks & watch-outs

• Watch-outs: built in 1956 — expect roof / HVAC / electrical / plumbing capex.
• Climate carrying-cost: extreme-heat days projected 7→21/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.

Recommended offer $75,106 (6.0% below list)

Questions for the listing agent

1. It's been on market 62 days. Have you received any prior offers? Is the seller open to a 6% concession, seller financing, or rate buy-down credit?
2. Built in 1956 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
3. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
4. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
5. 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.
6. 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.
7. How much new for-sale + rental construction is in the pipeline within 1–3 miles? Heavy new supply typically softens prices + rents 12–24 months out; constrained supply supports both.

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.
