What this means for you Summary
Snapshot
- This is a 1-bed/1.0-bath condo listed at $210k. Condition is rated poor.
Deal economics
- At list price, monthly cash flow is $274 ($3k/yr) — positive.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($3k rent vs $210k).
- Recommended offer: $185k (12.0% below list) — sets the bar for market timing.
- Cap rate 7.9% vs local median 2.1% in Aventura — 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 80/100 on livability (#127 in FL, #1,834 nationally) — a professional / high-income tenant draw. Strengths: health & safety A+, amenities A, commute A; Watch: crime D+, cost of living F.
- Miami-Dade (suburban): math 45% / reading 54% proficiency, ranked #40 of 73 in FL (top 55%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases; 64% free/reduced lunch — lower-income household profile, screen leases tightly.
- Zoned schools: Aventura Waterways K-8 Center (math 56% / reading 65%, grade B-, #664 of 2,144 statewide, top 32%, 2,168 students, 32% FRL); Highland Oaks Middle School (math 28% / reading 51%, grade F, #373 of 571 statewide, top 66%, 774 students, 50% FRL); Dr. Michael M. Krop Senior High (math 21% / reading 46%, grade F, #400 of 667 statewide, top 61%, 2,235 students, 49% FRL) — zoned schools average 44% FRL vs 64% district-wide (20 pts lower); this property's tenant base skews higher-income than the district average.
- Market conditions: Rents flat; 2334 active listings in the ZIP; 10,051 units permitted in Miami-Dade County in 2024 (7,758 in 5+ unit buildings).
- At $3,127/mo this rent would consume 56% of the median local household income ($67k/yr) (locally 17% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.
Forward outlook
- In year one you build about $3k of equity ($1k loan paydown + $1k appreciation (0.5% local appreciation)).
- Miami-Dade County population projected at +28% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
- At projected returns (0.5% appreciation + 0.9% rent growth), your $59k cash investment doubles in ~10 years — after that, you're playing with house money.
Negotiation context
- It's been on market 164 days — a 12% lower offer ($185k) is reasonable based on typical stale-listing flexibility.
- 6 sale attempts since 5y ago 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.
- Current owner paid $170k; 24% above their basis — modest negotiation headroom, anchor on the comps not their cost.
Risks & watch-outs
- Watch-outs: HOA is 25% of rent.
Questions for the listing agent
- It's been on market 164 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
- Have any recent inspections been done? Can we get a copy of the seller's disclosures and any deferred-maintenance estimates?
- What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
- 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?
- Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
- Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
- Schools are A-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?
- Crime grade is D in this area — have there been break-ins, vandalism, or insurance claims at this property in the last 3 years? What carrier currently insures it and at what premium?
- 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.
