Investor read

• This is a 2-bed/1.0-bath manufactured listed at $150k.
• At list price, monthly cash flow is $1k ($13k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($4k rent vs $150k).
• It's been on market 457 days — a 12% lower offer ($132k) is reasonable based on typical stale-listing flexibility.
• Recommended offer: $132k (12.0% below list) — sets the bar for market timing.
• In year one you build about $2k of equity ($1k loan paydown + $1k appreciation (0.7% local appreciation)).
• Location reads 64/100 on livability (#693 in FL) — a middle-class / working-renter tenant base. Strengths: crime A+, employment A+; Watch: housing C-, amenities F, commute F.
• Sarasota (urban): math 63% / reading 63% proficiency, ranked #7 of 73 in FL (top 10%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
• Zoned schools: Southside Elementary School (math 79% / reading 81%, grade A+, #110 of 2,144 statewide, top 5%, 687 students, 26% FRL); Booker Middle School (math 45% / reading 41%, grade D-, #331 of 571 statewide, top 59%, 950 students, 76% FRL); Booker High School (math 26% / reading 43%, grade F, #386 of 667 statewide, top 59%, 1,309 students, 68% FRL).
• Watch-outs: flood insurance adds $427/mo.
• Market conditions: 543 active listings in the ZIP; high-income renter base; 7,466 units permitted in Sarasota County in 2024 (2,138 in 5+ unit buildings).
• Sarasota County population projected at +20% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
• 3 sale attempts; this cycle's ask has dropped $9k (6%) from the opening price — seller is motivated, your offer sets the floor, not the list.
• At projected returns (0.7% appreciation + 3.0% rent growth), your $42k cash investment doubles in ~3 years — after that, you're playing with house money.
• 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→29/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
• Cap rate 18.5% vs local median 0.5% in Longboat Key — 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

• It's been on market 457 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
• Built in 1965 — 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?
• Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
• Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
• 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.
