What this means for you Summary

Snapshot

• This is a 2-bed/2.0-bath condo listed at $300k.

Deal economics

• At list price, monthly cash flow is $-355 ($-4k/yr) — negative.
• To cash-flow at today's rent, offer at most $237k (20.9% below list).
• Meets the 1% rule at list price ($4k rent vs $300k).
• Recommended offer: $237k (20.9% below list) — sets the bar for cash-flow.
• Cap rate 6.6% 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.

Location & tenants

• 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.
• 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).
• At $4,287/mo this rent would consume 77% 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.

Forward outlook

• In year one you build about $4k of equity ($2k loan paydown + $2k appreciation (0.5% local appreciation)).
• Miami-Dade County population projected at +28% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
• By year 8, paydown + projected appreciation supports a ~$32k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

• Only 1 days on market — expect competitive offers; lowballing is unlikely to land.

Risks & watch-outs

• Watch-outs: flood insurance adds $427/mo; HOA is 30% of rent.
• 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.

Recommended offer $237,150 (20.9% below list)

Questions for the listing agent

1. 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?
2. Built in 1971 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
3. What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
4. What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
5. 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?
6. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
7. 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?
8. 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?
9. 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.
10. 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.
11. How much new apartment / multifamily construction is in the pipeline within 1–3 miles? Heavy new supply (>2% of stock underway) typically softens rents 12–24 months out; light construction supports rent growth.

For passive investors: Depreciation is non-cash, so a rental often shows a tax loss while cash-flowing — sheltering income. Rental losses are passive: they offset passive income freely, and up to $25,000/yr can offset ordinary (W-2) income if you actively participate and your MAGI is under $100k (phasing out to $0 by $150k); unused losses carry forward. On sale, claimed depreciation is recaptured at up to 25%, and gains may owe capital-gains tax (a 1031 exchange can defer both). Figures are a year-1 estimate at your 24.0% rate — not tax advice; consult a CPA.
