What this means for you Summary

Snapshot

• This is a 4-bed/1.0-bath single-family listed at $339k.

Deal economics

• At list price, monthly cash flow is $608 ($7k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($4k rent vs $339k).
• Recommended offer: $334k (1.5% below list) — sets the bar for market timing.

Location & tenants

• Location reads 69/100 on livability (#482 in FL) — a middle-class / working-renter tenant base. Strengths: cost of living A+, housing A+, health & safety A+; Watch: crime F, amenities F, employment D-.
• Palm Beach (suburban): math 46% / reading 53% proficiency, ranked #34 of 73 in FL (top 47%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
• Zoned schools: West Riviera Elementary School (math 26% / reading 22%, grade F, #2,057 of 2,144 statewide, top 96%, 487 students, 83% FRL); John F. Kennedy Middle School (math 28% / reading 29%, grade F, #482 of 571 statewide, top 85%, 826 students, 78% FRL); Palm Beach Lakes High School (math 17% / reading 26%, grade F, #546 of 667 statewide, top 82%, 2,688 students, 70% FRL) — zoned schools average 77% FRL vs 52% district-wide (25 pts higher); higher-poverty schools than district average — tighter screening recommended.
• Zoned-school proficiency averages 25% at this address vs 50% district-wide (-25 pts) — the specific schools serving this property underperform the Palm Beach average; the district grade overstates school quality for this exact location.
• Market conditions: Rents rising (+3.1%/yr); 305 active listings in the ZIP; 18 comparable units currently listed for rent nearby; rentals at typical pace (median 26d on market — plan ~3-4 weeks tenant-placement turnaround); 3,974 units permitted in Palm Beach County in 2024 (1,012 in 5+ unit buildings).
• At $3,627/mo this rent would consume 73% of the median local household income ($60k/yr) (locally 2157% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.

Forward outlook

• Local home prices are declining (-3.0%/yr); year-one equity from $2k of loan paydown is wiped out by about $10k of value loss. Plan a longer hold.
• Palm Beach County population projected at +30% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.

Negotiation context

• It's been on market 18 days — a 2% lower offer ($334k) is reasonable based on typical stale-listing flexibility.
• Current owner paid $24k; list at $339k implies a 1343% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

• Climate carrying-cost: severe wind risk, 99% chance of damaging wind over 30y; extreme-heat days projected 7→24/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.

Recommended offer $333,915 (1.5% below list)

Questions for the listing agent

1. Built in 1972 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
2. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
3. 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?
4. 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?
5. 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.
6. 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.
7. How much new for-sale + rental construction is in the pipeline within 1–3 miles? Heavy new supply typically softens prices + rents 12–24 months out; constrained supply supports both.

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.
