Investor read

• This is a 1-bed/1.0-bath condo listed at $490k.
• At list price, monthly cash flow is $-1k ($-17k/yr) — negative.
• To cash-flow at today's rent, offer at most $418k (14.7% below list).
• To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $391k (20.2% below list).
• It's been on market 53 days — a 3% lower offer ($475k) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $391k (20.2% below list) — sets the bar for 1% rule.
• In year one you build about $5k of equity ($3k loan paydown + $1k appreciation (0.3% local appreciation)).
• Location reads 78/100 on livability (#177 in FL, #2,724 nationally) — a middle-class / working-renter tenant base. Strengths: amenities A+, commute A+, health & safety A+; Watch: employment C-, crime F, 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: Morningside K-8 Academy (math 38% / reading 52%, grade D-, #1,271 of 2,144 statewide, top 60%, 415 students, 69% FRL); Horace Mann Middle School (math 23% / reading 31%, grade F, #497 of 571 statewide, top 88%, 528 students, 76% FRL); Booker T. Washington Senior High (math 12% / reading 19%, grade F, #604 of 667 statewide, top 91%, 1,014 students, 60% FRL) — zoned schools at 68% FRL track the district average.
• Zoned-school proficiency averages 29% at this address vs 50% district-wide (-20 pts) — the specific schools serving this property underperform the Miami-Dade average; the district grade overstates school quality for this exact location.
• Watch-outs: HOA is 26% of rent.
• Market conditions: Rents rising (+2.7%/yr); 758 active listings in the ZIP; 1 comparable units currently listed for rent nearby; solid renter incomes; 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.
• 2 sale attempts since 6y 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.
• By year 6, paydown + projected appreciation supports a ~$31k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.
• Climate carrying-cost: moderate flood risk; 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 2.8% vs local median 1.9% in Miami — 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.

Questions for listing agent

• What do current leases actually rent for vs. the listed asking? Can we see a recent rent roll and the last 12 months of T-12 income?
• It's been on market 53 days. Have you received any prior offers? Is the seller open to a 20% 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?
• Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
• Schools are B-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 F 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?
• The area grade is low — what's the realistic commute time and amenity access for the typical tenant pool here? Any planned neighborhood developments (good or bad) we should know about?
