What this means for you Summary

Snapshot

  • This is a 2 × 2-bed/2.0-bath units multifamily listed at $340k.

Deal economics

  • At list price, monthly cash flow is $54 ($649/yr) — positive. Per door: $27/mo.
  • The deal already cash-flows at list — no discount required.
  • To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $295k (13.2% below list).
  • Recommended offer: $295k (13.2% below list) — sets the bar for 1% rule.
  • Cap rate 6.5% vs local median 2.8% in Sachse — 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 (#94 in TX, #3,263 nationally) — a middle-class / working-renter tenant base. Strengths: crime A+, employment A+, housing A+; Watch: amenities F, commute F.
  • Garland ISD (suburban): math 27% / reading 37% proficiency, ranked #553 of 826 in TX (top 67%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
  • Market conditions: Rents soft (-1.1%/yr); 182 active listings in the ZIP; 11 comparable units currently listed for rent nearby; rentals at typical pace (median 14d on market — plan ~3-4 weeks tenant-placement turnaround); high-income renter base; 12,577 units permitted in Dallas County in 2024 (6,829 in 5+ unit buildings).

Forward outlook

  • Local home prices are declining (-3.0%/yr); year-one equity from $2k of loan paydown is wiped out by about $10k of value loss. Plan a longer hold.
  • Dallas County population projected at +35% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.

Negotiation context

  • It's been on market 151 days — a 12% lower offer ($299k) is reasonable based on typical stale-listing flexibility.
  • 5 sale attempts since 15y ago; this cycle's ask has dropped $145k (30%) from the opening price — seller is motivated, your offer sets the floor, not the list.

Risks & watch-outs

  • Climate carrying-cost: major wind risk, 27% chance of damaging wind over 30y; extreme-heat days projected 7→24/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Recommended offer $295,200 (13.2% below list)

Questions for the listing agent

  1. It's been on market 151 days. Have you received any prior offers? Is the seller open to a 13% concession, seller financing, or rate buy-down credit?
  2. Can we see the unit-by-unit rent roll, current vacancy, and any below-market leases? What's the average tenancy length?
  3. What capital expenditures (roof, boiler, parking lot, exteriors) have been made in the last 5 years, and what's planned in the next 2?
  4. Why hasn't it sold? Are there any deal-killer items the seller is aware of (foundation, flood, title, zoning, code violations)?
  5. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  6. 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?
  7. 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?
  8. 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.
  9. 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.
  10. 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.
