What this means for you Summary

Snapshot

  • This is a 3-bed/2.5-bath townhouse listed at $506k.

Deal economics

  • At list price, monthly cash flow is $-322 ($-4k/yr) — negative.
  • To cash-flow at today's rent, offer at most $449k (11.3% below list).
  • To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $483k (4.5% below list).
  • Recommended offer: $449k (11.3% below list) — sets the bar for cash-flow.
  • Cap rate 6.5% vs local median 1.7% in St. Simons — 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 D — affects rentability + tenant quality, not the cash-flow math above.
  • Glynn County (other): math 37% / reading 42% proficiency, ranked #47 of 174 in GA (top 27%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
  • Market conditions: Rents rising (+2.3%/yr); 577 active listings in the ZIP; 3 comparable units currently listed for rent nearby; rentals lingering (median 44d on market — plan ~5-8 weeks vacancy on turnover, expect pricing pressure); 100% of comp listings sitting > 30 days — soft ceiling on asking rent; solid renter incomes; 734 units permitted in Glynn County in 2024 (136 in 5+ unit buildings).
  • At $4,829/mo this rent would consume 53% of the median local household income ($109k/yr) (locally 339% of renters already pay >50% of income on rent) — very limited rent-growth headroom before tenants either downsize or default.

Forward outlook

  • Local home prices are declining (-3.0%/yr); year-one equity from $3k of loan paydown is wiped out by about $15k of value loss. Plan a longer hold.
  • Glynn County population projected at +13% by 2050 — modest demand growth; plan on rents tracking national, not racing it.

Negotiation context

  • It's been on market 55 days — a 3% lower offer ($491k) is reasonable based on typical stale-listing flexibility.
  • 2 sale attempts since 9y 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 $312k; list at $506k implies a 62% gain — meaningful room to come down on a strong offer.

Risks & watch-outs

  • Watch-outs: flood insurance adds $427/mo.
  • 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→20/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Recommended offer $448,968 (11.3% below list)

Questions for the listing agent

  1. 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?
  2. It's been on market 55 days. Have you received any prior offers? Is the seller open to a 11% concession, seller financing, or rate buy-down credit?
  3. What's the actual annual flood-insurance premium (NFIP or private), and is the property in a SFHA with mandatory coverage?
  4. What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
  5. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  6. 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?
  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.
