What this means for you Summary

Snapshot

• This is a 4-bed/2.5-bath single-family listed at $500k.

Deal economics

• At list price, monthly cash flow is $529 ($6k/yr) — positive.
• The deal already cash-flows at list — no discount required.
• Meets the 1% rule at list price ($5k rent vs $500k).
• Recommended offer: $440k (12.0% below list) — sets the bar for market timing.
• Cap rate 7.6% vs local median 2.4% in Charleston — 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 76/100 on livability (#22 in SC, #3,336 nationally) — a middle-class / working-renter tenant base. Strengths: amenities A+, housing A+, health & safety A+; Watch: crime D+, commute F, cost of living D-.
• Berkeley 01 (suburban): math 35% / reading 48% proficiency, ranked #30 of 80 in SC (top 38%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
• Zoned schools: Cainhoy Elementary (math 2% / reading 12%, grade F, #594 of 597 statewide, top 100%, 154 students, 100% FRL); Philip Simmons Middle (math 31% / reading 48%, grade F, #82 of 229 statewide, top 37%, 428 students, 35% FRL); Philip Simmons High (math 42% / reading 92%, grade B, #73 of 196 statewide, top 41%, 771 students, 21% FRL) — zoned schools at 52% FRL track the district average.
• Market conditions: 69 active listings in the ZIP; 3,183 units permitted in Berkeley County in 2024 (580 in 5+ unit buildings).

Forward outlook

• Local home prices are declining (-1.1%/yr); year-one equity from $3k of loan paydown is wiped out by about $6k of value loss. Plan a longer hold.
• Berkeley County population projected at +48% 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 ($440k) is reasonable based on typical stale-listing flexibility.

Risks & watch-outs

• Climate carrying-cost: severe wind risk, 98% chance of damaging wind over 30y; major wildfire risk; extreme-heat days projected 7→18/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.

Recommended offer $439,991 (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. What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
3. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
4. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
5. Schools are A-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?
6. 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?
7. 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.
8. 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.
9. 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.
