Listing remarks
Here's your chance to own a duplex in 63118 for a reasonable price. This duplex offers a 2 bedroom unit upstairs and a 1 bedroom on the main level. The upstairs unit is currently unoccupied and would require some work to be finished. Each unit has a full bathroom. Both units offer some beautiful wood work, hardwood flooring and coffered ceilings. The main level is currently being lived in and is in good shape. This could be a great money making property for someone to live in while finishing the other side to rent out. Or finish the upper unit and rent out both units. Fenced in backyard with a two car garage out back. Lots of potential!

What this means for you Summary
Snapshot
- This is a 2 × 3-bed/2.0-bath units multifamily listed at $130k.
Deal economics
- At list price, monthly cash flow is $2k ($19k/yr) — positive. Per door: $785/mo.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($3k rent vs $130k).
- Recommended offer: $128k (1.5% below list) — sets the bar for market timing.
- Cap rate 20.8% vs local median 5.0% in 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.
- St. Louis City (urban): math 10% / reading 18% proficiency, ranked #312 of 324 in MO (top 96%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover; 80% free/reduced lunch — lower-income household profile, screen leases tightly.
- Zoned schools: Froebel Elem. (math 8% / reading 8%, grade F, #1,052 of 1,115 statewide, top 95%, 176 students, 98% FRL); Roosevelt High (math 2% / reading 8%, grade F, #517 of 521 statewide, top 100%, 460 students, 99% FRL) — zoned schools average 99% FRL vs 80% district-wide (18 pts higher); higher-poverty schools than district average — tighter screening recommended.
- Market conditions: Rents rising fast (+4.9%/yr); 240 active listings in the ZIP; 294 units permitted in St. Louis city in 2024 (227 in 5+ unit buildings).
- At $2,973/mo this rent would consume 62% of the median local household income ($58k/yr) (locally 1495% 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 $899 of loan paydown is wiped out by about $4k of value loss. Plan a longer hold.
- St. Louis County population projected to shrink 6% by 2050 — rents likely to lag national; underwrite the cash flow, not the appreciation.
- At projected returns (-3.0% appreciation + 4.9% rent growth), your $36k cash investment doubles in ~3 years — after that, you're playing with house money.
Negotiation context
- It's been on market 21 days — a 2% lower offer ($128k) is reasonable based on typical stale-listing flexibility.
- Current owner paid $45k; list at $130k implies a 189% gain — meaningful room to come down on a strong offer.
Risks & watch-outs
- Watch-outs: built in 1912 — expect roof / HVAC / electrical / plumbing capex.
- Climate carrying-cost: moderate flood risk; extreme-heat days projected 7→21/yr by 2055 (HVAC capex compounding) — 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 1912 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
- 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.
