Investor read

• This is a 1-bed/1.0-bath condo listed at $224k.
• At list price, monthly cash flow is $756 ($9k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($4k rent vs $224k).
• It's been on market 89 days — a 6% lower offer ($211k) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $211k (6.0% below list) — sets the bar for market timing.
• In year one you build about $3k of equity ($2k 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: 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; 1879 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.
• 5 sale attempts since 9y ago; this cycle's ask is 13076% above the opening price — seller raised mid-cycle; expect resistance to lowballs.
• At projected returns (0.5% appreciation + 0.9% rent growth), your $63k cash investment doubles in ~6 years — after that, you're playing with house money.
• By year 10, paydown + projected appreciation supports a ~$31k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.
• Cap rate 10.3% 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 $4,026/mo this rent would consume 72% 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 89 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.
