What this means for you Summary

Snapshot

  • This is a 1-bed/1.5-bath condo listed at $110k. Condition is rated good.

Deal economics

  • At list price, monthly cash flow is $201 ($2k/yr) — positive.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($2k rent vs $110k).
  • Recommended offer: $97k (12.0% below list) — sets the bar for market timing.
  • Cap rate 8.5% vs local median 5.5% in North River Shores — 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 74/100 on livability (#292 in FL, #4,906 nationally) — a middle-class / working-renter tenant base. Strengths: crime A+, housing A+, employment B+; Watch: amenities F, commute F, health & safety D-.
  • Martin (suburban): math 52% / reading 53% proficiency, ranked #24 of 73 in FL (top 33%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
  • Zoned schools: Felix A Williams Elementary School (math 61% / reading 67%, grade B, #552 of 2,144 statewide, top 26%, 531 students, 40% FRL); Stuart Middle School (math 55% / reading 55%, grade B-, #180 of 571 statewide, top 32%, 867 students, 49% FRL); Jensen Beach High School (math 53% / reading 71%, grade B-, #98 of 667 statewide, top 15%, 1,584 students, 36% FRL) — zoned schools at 42% FRL track the district average.
  • Market conditions: Rents soft (-0.7%/yr); 321 active listings in the ZIP; 9 comparable units currently listed for rent nearby; rentals at typical pace (median 16d on market — plan ~3-4 weeks tenant-placement turnaround); 44% of comp listings sitting > 30 days — soft ceiling on asking rent; 737 units permitted in Martin County in 2024 (167 in 5+ unit buildings).
  • This rent runs 31% of the median local income ($63k/yr) — at the standard rent-burdened threshold; future hikes will face affordability resistance.

Forward outlook

  • Local home prices are declining (-3.0%/yr); year-one equity from $761 of loan paydown is wiped out by about $3k of value loss. Plan a longer hold.
  • Martin County population projected at +19% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.

Negotiation context

  • It's been on market 134 days — a 12% lower offer ($97k) is reasonable based on typical stale-listing flexibility.
  • 3 sale attempts since 18y ago with the ask held roughly flat each time — persistent listings suggest the price (not the market) is what's stuck; bring a comps-based counter.
  • Current owner paid $77k; 43% above their basis — modest negotiation headroom, anchor on the comps not their cost.

Risks & watch-outs

  • Watch-outs: HOA is 25% of rent.
  • Climate carrying-cost: severe wind risk, 99% chance of damaging wind over 30y; extreme-heat days projected 7→25/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Recommended offer $96,800 (12.0% below list)

Questions for the listing agent

  1. It's been on market 134 days. Have you received any prior offers? Is the seller open to a 12% concession, seller financing, or rate buy-down credit?
  2. Built in 1976 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  3. What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
  4. 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?
  5. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
  6. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  7. Schools are D-rated, which usually means shorter tenancies and higher turnover. Who's the typical renter profile here, and what's been the actual vacancy rate?
  8. This sits on a lake — are riparian / water-frontage rights deeded with the parcel? Any dock permits, shoreline easements, or HOA water-use restrictions?
  9. What's the documented flood / surge / shoreline-erosion history here (FEMA AND non-FEMA — e.g., storm surge, creek backup, septic-field saturation)?
  10. Any water-quality or seasonal algae-bloom issues that affect tenant satisfaction or short-term-rental demand?
  11. 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.
  12. 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.
  13. 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.
