What this means for you Summary

Snapshot

• This is a 3-bed/2.0-bath single-family listed at $186k.

Deal economics

• At list price, monthly cash flow is $-176 ($-2k/yr) — negative.
• To cash-flow at today's rent, offer at most $161k (13.7% below list).
• To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $140k (24.5% below list).
• Recommended offer: $140k (24.5% below list) — sets the bar for 1% rule.
• Cap rate 5.2% vs local median 3.8% in San Antonio — 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 80/100 on livability (#31 in TX, #1,616 nationally) — a professional / high-income tenant draw. Strengths: amenities A+, commute A+, cost of living A+; Watch: crime F.
• Southside ISD (rural): math 16% / reading 25% proficiency, ranked #771 of 826 in TX (top 93%) — low school quality limits family demand, transient renter base, plan for 1-2y turnover; 76% free/reduced lunch — lower-income household profile, screen leases tightly.
• Zoned schools: Freedom El (math 15% / reading 26%, grade F, #3,515 of 4,322 statewide, top 82%, 562 students, 93% FRL); Julius L Matthey Middle (math 17% / reading 25%, grade F, #1,387 of 1,662 statewide, top 85%, 604 students, 92% FRL); Southside H S (math 18% / reading 25%, grade F, #1,377 of 1,632 statewide, top 85%, 1,685 students, 85% FRL).
• Market conditions: 359 active listings in the ZIP; 22 comparable units currently listed for rent nearby; rentals at typical pace (median 20d on market — plan ~3-4 weeks tenant-placement turnaround); 8,308 units permitted in Bexar County in 2024 (2,506 in 5+ unit buildings).

Forward outlook

• In year one you build about $9k of equity ($1k loan paydown + $7k appreciation (3.9% local appreciation)).
• Bexar County population projected at +50% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
• By year 5, paydown + projected appreciation supports a ~$37k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

• Only 6 days on market — expect competitive offers; lowballing is unlikely to land.

Recommended offer $140,433 (24.5% 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. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
3. 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?
4. 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?
5. 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.
6. 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.
7. 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.
