Investor read

• This is a 2-bed/2.0-bath condo listed at $65k.
• At list price, monthly cash flow is $371 ($4k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($3k rent vs $65k).
• Only 13 days on market — expect competitive offers; lowballing is unlikely to land.
• Local home prices are declining (-3.0%/yr); year-one equity from $449 of loan paydown is wiped out by about $2k of value loss. Plan a longer hold.
• Location reads 72/100 on livability (#351 in FL) — a middle-class / working-renter tenant base. Strengths: housing A+, health & safety B+, cost of living B; Watch: amenities D+, crime D-, commute F.
• 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: Crosspointe Elementary School (math 36% / reading 45%, grade F, #1,471 of 2,144 statewide, top 69%, 652 students, 75% FRL); Atlantic High School (math 28% / reading 52%, grade F, #296 of 667 statewide, top 45%, 1,889 students, 59% FRL) — zoned schools average 67% FRL vs 52% district-wide (15 pts higher); higher-poverty schools than district average — tighter screening recommended.
• Watch-outs: HOA is 54% of rent.
• Market conditions: Rents soft (-0.6%/yr); 457 active listings in the ZIP; 40 comparable units currently listed for rent nearby; rentals at typical pace (median 22d on market — plan ~3-4 weeks tenant-placement turnaround); solid renter incomes; 3,974 units permitted in Palm Beach County in 2024 (1,012 in 5+ unit buildings).
• Palm Beach County population projected at +30% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
• 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.
• Cap rate 13.2% vs local median 4.3% in Boynton 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 $3,075/mo this rent would consume 49% of the median local household income ($76k/yr) (locally 1813% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.

Questions for listing agent

• 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.
• 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?
• 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?
• 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.
• 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.
