Investor read

• This is a 1-bed/1.0-bath condo listed at $210k.
• At list price, monthly cash flow is $821 ($10k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($4k rent vs $210k).
• It's been on market 67 days — a 6% lower offer ($197k) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $197k (6.0% below list) — sets the bar for market timing.
• In year one you build about $3k of equity ($1k loan paydown + $1k appreciation (0.5% local appreciation)).
• 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.
• Watch-outs: HOA is 21% of rent.
• Market conditions: Rents flat; 1870 active listings in the ZIP; 10,051 units permitted in Miami-Dade County in 2024 (7,758 in 5+ unit buildings).
• Miami-Dade County population projected at +28% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
• 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.
• At projected returns (0.5% appreciation + 0.9% rent growth), your $59k cash investment doubles in ~5 years — after that, you're playing with house money.
• Cap rate 11.0% 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.
• At $3,820/mo this rent would consume 68% 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.

Questions for listing agent

• It's been on market 67 days. Have you received any prior offers? Is the seller open to a 6% concession, seller financing, or rate buy-down credit?
• 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.
