What this means for you Summary

Snapshot

• This is a 4-bed/2.0-bath single-family listed at $368k.

Deal economics

• At list price, monthly cash flow is $-436 ($-5k/yr) — negative.
• To cash-flow at today's rent, offer at most $291k (20.9% below list).
• To meet the 1% rule (rent ≥ 1% of price), the offer needs to be $227k (38.3% below list).
• Recommended offer: $227k (38.3% below list) — sets the bar for 1% rule.
• Cap rate 4.9% vs local median 3.8% in San Antonio — meaningfully above typical; check what's discounted (condition, days-on-market, listing class) to confirm the premium yield is real.

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.
• North East ISD (urban): math 38% / reading 49% proficiency, ranked #276 of 826 in TX (top 33%) — families likely to look elsewhere, expect single-tenant / working-renter base with shorter leases.
• Zoned schools: Bulverde Creek (math 51% / reading 58%, grade C, #621 of 4,322 statewide, top 15%, 1,003 students, 39% FRL); Hill Middle (math 51% / reading 64%, grade B, #206 of 1,662 statewide, top 13%, 1,044 students, 28% FRL); Johnson H S (math 69% / reading 80%, grade B+, #82 of 1,632 statewide, top 6%, 3,202 students, 24% FRL).
• Zoned-school proficiency averages 62% at this address vs 44% district-wide (+19 pts) — the actual schools serving this property are materially stronger than the North East ISD average implies; a family-tenant draw the district grade alone would hide.
• Market conditions: 230 active listings in the ZIP; 28 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 $39k of equity ($3k loan paydown + $37k appreciation (10.0% local appreciation)).
• Bexar County population projected at +50% by 2050 — long-run rental-demand tailwind backs the buy-and-hold thesis.
• By year 2, paydown + projected appreciation supports a ~$63k cash-out refi (75% LTV) — recoverable capital for the next deal without selling this one.

Negotiation context

• It's been on market 38 days — a 3% lower offer ($357k) is reasonable based on typical stale-listing flexibility.

Recommended offer $227,106 (38.3% 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 38 days. Have you received any prior offers? Is the seller open to a 38% concession, seller financing, or rate buy-down credit?
3. What does the HOA fee cover, when was the last increase, and are there any pending special assessments or reserve-fund shortfalls?
4. Is there a deadline driving the sale (1031 exchange, divorce, estate, relocation)? That informs how much negotiation room exists.
5. 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?
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.
