Investor read

• This is a 1-bed/1.0-bath condo listed at $204k.
• At list price, monthly cash flow is $213 ($3k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($3k rent vs $204k).
• Only 12 days on market — expect competitive offers; lowballing is unlikely to land.
• Local home prices are declining (-2.2%/yr); year-one equity from $1k of loan paydown is wiped out by about $4k of value loss. Plan a longer hold.
• Location reads 80/100 on livability (#108 in FL, #1,672 nationally) — a professional / high-income tenant draw. Strengths: crime A+, commute A+, health & safety A+; Watch: housing C-, amenities 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: Miami Beach Feinberg/Fisher K-8 (math 37% / reading 34%, grade F, #1,684 of 2,144 statewide, top 79%, 842 students, 61% FRL); Miami Beach Nautilus Middle School (math 46% / reading 58%, grade C+, #217 of 571 statewide, top 40%, 918 students, 44% FRL); Miami Beach Senior High School (math 21% / reading 48%, grade F, #386 of 667 statewide, top 59%, 2,175 students, 40% FRL) — zoned schools average 48% FRL vs 64% district-wide (16 pts lower); this property's tenant base skews higher-income than the district average.
• Watch-outs: flood insurance adds $427/mo; built in 1939 — expect roof / HVAC / electrical / plumbing capex.
• Market conditions: Rents soft (-0.4%/yr); 1224 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 5y ago; this cycle's ask is 10075% above the opening price — seller raised mid-cycle; expect resistance to lowballs.
• 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 8→32/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
• Cap rate 10.1% vs local median 1.5% in Miami Beach — 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 $3,255/mo this rent would consume 56% of the median local household income ($70k/yr) (locally 4052% 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 1939 — 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?
• 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.
