What this means for you Summary

Snapshot

• This is a 2-bed/1.0-bath condo listed at $100k.

Deal economics

• At list price, monthly cash flow is $414 ($5k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($2k rent vs $100k).
• Recommended offer: $88k (12.0% below list) — sets the bar for market timing.
• Cap rate 11.3% vs local median 3.1% in Lake St. Louis — 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: area grade B — affects rentability + tenant quality, not the cash-flow math above.
• Wentzville R-IV (suburban): math 44% / reading 52% proficiency, ranked #32 of 324 in MO (top 10%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases; only 18% free/reduced lunch — higher-income household profile.
• Market conditions: Rents rising fast (+4.2%/yr); 230 active listings in the ZIP; 2 comparable units currently listed for rent nearby; high-income renter base; 2,021 units permitted in St. Charles County in 2024 (568 in 5+ unit buildings).
• This rent is only 17% of the median local income ($138k/yr) — well below the 30% rent-burden line; pricing power to push rent on renewal without tenant pushback.

Forward outlook

• Local home prices are declining (-3.0%/yr); year-one equity from $691 of loan paydown is wiped out by about $3k of value loss. Plan a longer hold.
• St. Charles County population projected at +22% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
• At projected returns (-3.0% appreciation + 4.2% rent growth), your $28k cash investment doubles in ~7 years — after that, you're playing with house money.

Negotiation context

• It's been on market 145 days — a 12% lower offer ($88k) is reasonable based on typical stale-listing flexibility.
• 3 sale attempts; this cycle's ask has dropped $20k (17%) from the opening price — seller is motivated, your offer sets the floor, not the list.
• Current owner paid $56k; list at $100k implies a 77% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

• Watch-outs: HOA is 22% of rent.
• Climate carrying-cost: extreme-heat days projected 7→20/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.

Recommended offer $87,912 (12.0% below list)

Questions for the listing agent

1. It's been on market 145 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
2. Built in 1970 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
3. What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
4. Any open or pending special assessments — roof, HVAC, plumbing, elevator, façade? What's the per-unit balance and payoff schedule, and is the seller paying it off at close or rolling it to the buyer?
5. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
6. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
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 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.
