Listing remarks

For Sale by Owner/Broker Stabilized duplex investment opportunity in University City featuring two 2-bedroom, 1-bath units, both fully occupied.

What this means for you Summary

Snapshot

  • This is a 2 × 2-bed/1.0-bath units multifamily listed at $185k.

Deal economics

  • At list price, monthly cash flow is $915 ($11k/yr) — positive. Per door: $457/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($3k rent vs $185k).
  • Cap rate 12.7% vs local median 4.9% in University City — 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 73/100 on livability (#84 in MO) — a middle-class / working-renter tenant base. Strengths: employment A+, housing A+, cost of living B; Watch: amenities D-, commute D-, health & safety F.
  • University City (suburban): math 15% / reading 26% proficiency, ranked #297 of 324 in MO (top 92%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover; 67% free/reduced lunch — lower-income household profile, screen leases tightly.
  • Market conditions: Rents rising (+3.6%/yr); 162 active listings in the ZIP; 33 comparable units currently listed for rent nearby; rentals at typical pace (median 18d on market — plan ~3-4 weeks tenant-placement turnaround); solid renter incomes; 920 units permitted in St. Louis County in 2024 (250 in 5+ unit buildings).
  • This rent runs 38% of the median local income ($86k/yr) — at the standard rent-burdened threshold; future hikes will face affordability resistance.

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.
  • At projected returns (-3.0% appreciation + 3.6% rent growth), your $52k cash investment doubles in ~6 years — after that, you're playing with house money.

Negotiation context

  • Only 1 days on market — expect competitive offers; lowballing is unlikely to land.

Risks & watch-outs

  • Watch-outs: flood insurance adds $66/mo.
  • Climate carrying-cost: severe flood risk; extreme-heat days projected 7→21/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Recommended offer $185,000

Questions for the listing agent

  1. Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
  2. What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
  3. Built in 1960 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  4. What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
  5. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  6. Schools are B-rated — typically a magnet for longer-tenancy family renters. What's the average tenant stay here, and is there a school-zone premium baked into asking?
  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.
