What this means for you Summary
Snapshot
- This is a 3-bed/2.0-bath condo listed at $300k.
Deal economics
- At list price, monthly cash flow is $172 ($2k/yr) — positive.
- The deal already cash-flows at list — no discount required.
- Meets the 1% rule at list price ($5k rent vs $300k).
- Recommended offer: $291k (3.0% below list) — sets the bar for market timing.
- Cap rate 8.7% vs local median 2.6% 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: schools A+, health & safety A+, amenities 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.
- Market conditions: Rents flat; 1870 active listings in the ZIP; 4 comparable units currently listed for rent nearby; rentals leasing fast (median 11d on market — plan ~1-2 weeks tenant-placement turnaround); 10,051 units permitted in Miami-Dade County in 2024 (7,758 in 5+ unit buildings).
- At $5,476/mo this rent would consume 98% of the median local household income ($67k/yr) (locally 3106% 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 $4k of equity ($2k loan paydown + $2k 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.
- By year 8, paydown + projected appreciation supports a ~$32k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.
Negotiation context
- It's been on market 38 days — a 3% lower offer ($291k) is reasonable based on typical stale-listing flexibility.
- 6 sale attempts since 8y ago; this cycle's ask has dropped $50k (14%) from the opening price — seller is motivated, your offer sets the floor, not the list.
Risks & watch-outs
- Watch-outs: flood insurance adds $427/mo; HOA is 28% of rent.
- Climate carrying-cost: in FEMA flood zone AE (mandatory federal flood insurance); severe wind risk, 99% chance of damaging wind over 30y; extreme-heat days projected 7→24/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Questions for the listing agent
- It's been on market 38 days. Have you received any prior offers? Is the seller open to a 3% concession, seller financing, or rate buy-down credit?
- What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
- 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?
- 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.
