What this means for you Summary

Snapshot

• This is a 2-bed/3.0-bath single-family listed at $315k.

Deal economics

• At list price, monthly cash flow is $124 ($1k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $256k (18.7% below list).
• Recommended offer: $256k (18.7% below list) — sets the bar for 1% rule.
• Cap rate 6.8% vs local median 2.6% in St. Petersburg — 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: area grade C — affects rentability + tenant quality, not the cash-flow math above.
• Pinellas (suburban): math 51% / reading 51% proficiency, ranked #31 of 73 in FL (top 42%) — acceptable for families but not a draw, mixed tenant base, ~2y average lease.
• Zoned schools: Northwest Elementary School (math 56% / reading 50%, grade C, #963 of 2,144 statewide, top 45%, 477 students, 63% FRL); Tyrone Middle School (math 35% / reading 28%, grade F, #453 of 571 statewide, top 81%, 847 students, 68% FRL); Boca Ciega High School (math 24% / reading 33%, grade F, #458 of 667 statewide, top 69%, 1,423 students, 64% FRL) — zoned schools average 65% FRL vs 48% district-wide (17 pts higher); higher-poverty schools than district average — tighter screening recommended.
• Zoned-school proficiency averages 38% at this address vs 51% district-wide (-13 pts) — the specific schools serving this property underperform the Pinellas average; the district grade overstates school quality for this exact location.
• Market conditions: Rents soft (-0.5%/yr); 320 active listings in the ZIP; 18 comparable units currently listed for rent nearby; rentals at typical pace (median 19d on market — plan ~3-4 weeks tenant-placement turnaround); solid renter incomes; 2,676 units permitted in Pinellas County in 2024 (1,422 in 5+ unit buildings).
• This rent runs 39% of the median local income ($79k/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 $2k of loan paydown is wiped out by about $9k of value loss. Plan a longer hold.
• Pinellas County population projected at +14% by 2050 — modest demand growth; plan on rents tracking national, not racing it.

Negotiation context

• Only 4 days on market — expect competitive offers; lowballing is unlikely to land.
• 3 sale attempts since 19y 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 $75k; list at $315k implies a 320% 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→25/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.

Recommended offer $256,034 (18.7% below list)

Questions for the listing agent

1. Built in 1968 — 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. 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.
4. 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.
5. 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.
