What this means for you Summary

Snapshot

  • This is a 2-bed/1.0-bath single-family listed at $72k.

Deal economics

  • At list price, monthly cash flow is $308 ($4k/yr) — positive.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($1k rent vs $72k).
  • Recommended offer: $65k (9.0% below list) — sets the bar for market timing.

Location & tenants

  • Location reads 69/100 on livability (#438 in IL) — a middle-class / working-renter tenant base. Strengths: crime A+, cost of living A+, housing A+; Watch: health & safety C-, employment D, amenities F.
  • Ottawa Twp Hsd 140 (town): math 25% / reading 30% proficiency, ranked #545 of 919 in IL (top 59%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover.
  • Zoned schools: Ottawa Township High School (math 17% / reading 27%, grade F, #319 of 693 statewide, top 50%, 1,261 students, 0% FRL).
  • Market conditions: 54 active listings in the ZIP; 82 units permitted in LaSalle County in 2024 (0 in 5+ unit buildings).

Forward outlook

  • Local home prices are declining (-3.0%/yr); year-one equity from $497 of loan paydown is wiped out by about $2k of value loss. Plan a longer hold.
  • LaSalle County population projected at -16% 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 $20k cash investment doubles in ~7 years — after that, you're playing with house money.

Negotiation context

  • It's been on market 113 days — a 9% lower offer ($65k) is reasonable based on typical stale-listing flexibility.
  • 2 sale attempts 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.

Risks & watch-outs

  • Watch-outs: property tax is 2.7% of price; built in 1925 — expect roof / HVAC / electrical / plumbing capex.
Recommended offer $65,429 (9.0% below list)

Questions for the listing agent

  1. It's been on market 113 days. Have you received any prior offers? Is the seller open to a 9% concession, seller financing, or rate buy-down credit?
  2. Built in 1925 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  3. Property tax is high relative to price — has the assessment been appealed recently, and will the sale trigger a re-assessment?
  4. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
  5. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  6. Schools are F-rated, which usually means shorter tenancies and higher turnover. Who's the typical renter profile here, and what's been the actual vacancy rate?
  7. 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.
  8. 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.
  9. 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.
