Investor read

• This is a 2-bed/1.0-bath single-family listed at $170k. Condition is rated good.
• At list price, monthly cash flow is $-6 ($-76/yr) — negative.
• To cash-flow at today's rent, offer at most $169k (0.5% below list).
• To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $148k (13.0% below list).
• Only 6 days on market — expect competitive offers; lowballing is unlikely to land.
• Recommended offer: $148k (13.0% below list) — sets the bar for 1% rule.
• Local home prices are declining (-3.0%/yr); year-one equity from $1k of loan paydown is wiped out by about $5k of value loss. Plan a longer hold.
• Location reads 83/100 on livability (#50 in FL, #911 nationally) — a professional / high-income tenant draw. Strengths: amenities A+, commute A+, housing A+.
• Duval (urban): math 46% / reading 45% proficiency, ranked #48 of 73 in FL (top 66%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
• Watch-outs: built in 1956 — expect roof / HVAC / electrical / plumbing capex.
• Market conditions: 107 active listings in the ZIP; solid renter incomes; 6,503 units permitted in Duval County in 2024 (1,131 in 5+ unit buildings).
• Duval County population projected at +19% 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→19/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
• Cap rate 6.2% vs local median 4.0% in Jacksonville — 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

• What do current leases actually rent for vs. the listed asking? Can we see a recent rent roll and the last 12 months of T-12 income?
• Built in 1956 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
• Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
• 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?
• 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 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.
