What this means for you Summary

Snapshot

  • This is a 2 × 2-bed/1-bath units multifamily listed at $179k.

Deal economics

  • At list price, monthly cash flow is $530 ($6k/yr) — positive. Per door: $265/mo.
  • The deal already cash-flows at list — no discount required.
  • Meets the 1% rule at list price ($2k rent vs $179k).
  • Recommended offer: $174k (3.0% below list) — sets the bar for market timing.

Location & tenants

  • Location reads 80/100 on livability (#37 in TX, #1,749 nationally) — a professional / high-income tenant draw. Strengths: commute A+, cost of living A+, housing A+; Watch: employment C-, crime F.
  • Lubbock ISD (urban): math 36% / reading 39% proficiency, ranked #481 of 826 in TX (top 58%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases; 60% free/reduced lunch — lower-income household profile, screen leases tightly.
  • Zoned schools: Overton El (math 22% / reading 27%, grade F, #3,052 of 4,322 statewide, top 74%, 277 students, 84% FRL); Mackenzie Middle (math 19% / reading 27%, grade F, #1,327 of 1,662 statewide, top 81%, 515 students, 88% FRL); Coronado H S (math 34% / reading 38%, grade F, #930 of 1,632 statewide, top 57%, 1,960 students, 66% FRL) — zoned schools average 79% FRL vs 60% district-wide (19 pts higher); higher-poverty schools than district average — tighter screening recommended.
  • Market conditions: Rents rising fast (+5.4%/yr); 110 active listings in the ZIP; 40 comparable units currently listed for rent nearby; rentals at typical pace (median 22d on market — plan ~3-4 weeks tenant-placement turnaround); 48% of comp listings sitting > 30 days — soft ceiling on asking rent; lower-income renter base — watch delinquency; 2,219 units permitted in Lubbock County in 2024 (252 in 5+ unit buildings).
  • At $2,259/mo this rent would consume 61% of the median local household income ($45k/yr) (locally 1068% 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 $1k of loan paydown is wiped out by about $5k of value loss. Plan a longer hold.
  • Lubbock County population projected at +39% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
  • At projected returns (-3.0% appreciation + 5.4% rent growth), your $50k cash investment doubles in ~8 years — after that, you're playing with house money.

Negotiation context

  • It's been on market 34 days — a 3% lower offer ($174k) is reasonable based on typical stale-listing flexibility.

Risks & watch-outs

  • Climate carrying-cost: extreme-heat days projected 7→21/yr by 2055 (HVAC capex compounding) — expect insurance premiums to compound above CPI over the hold.
Recommended offer $173,630 (3.0% below list)

Questions for the listing agent

  1. It's been on market 34 days. Have you received any prior offers? Is the seller open to a 3% 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. Built in 1960 — when were the roof, HVAC, electrical panel, plumbing, and water heater last replaced?
  5. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
  6. Schools are D-rated, which usually means shorter tenancies and higher turnover. Who's the typical renter profile here, and what's been the actual vacancy rate?
  7. Crime grade is F 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?
  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.
