Investor read

• This is a 1-bed/1.0-bath condo listed at $175k.
• At list price, monthly cash flow is $341 ($4k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($4k rent vs $175k).
• It's been on market 16 days — a 2% lower offer ($172k) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $172k (1.5% below list) — sets the bar for market timing.
• In year one you build about $2k of equity ($1k loan paydown + $922 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: flood insurance adds $427/mo; HOA is 26% of rent.
• Market conditions: Rents flat; 1878 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.
• 4 sale attempts since 7y 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.
• At projected returns (0.5% appreciation + 0.9% rent growth), your $49k cash investment doubles in ~9 years — after that, you're playing with house money.
• 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→28/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
• Cap rate 11.6% 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 $3,720/mo this rent would consume 67% 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

• Built in 1971 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
• 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.
