Comal County presents a cautious income-versus-price screen, with a clear tension between a high entry price and modest gross income. Zillow’s 2026-06 observation puts median home value at $436,283 and median asking rent at $1,534 per month, producing a 4.22% gross yield before taxes, insurance, repairs, vacancy, management, or financing. The thesis is therefore cost-sensitive: buyers pursuing rental income should investigate property-level expenses, while buyers depending on rent growth or quick resale should be cautious.
Market rent was 107.6% of HUD’s $1,426 two-bedroom FMR, but FMR is a payment standard, not an estimate of asking rent or achieved rent. The effective property-tax rate was 1.13%, and median annual tax was $4,833; those carrying costs make the gross yield materially different from a net return. FHFA’s 2025 repeat-transaction HPI rose 0.6%. That is an appreciation index, not a home value, and its vintage and method should not be averaged with Zillow’s observation.
Demand evidence is mixed rather than empty. Realtor.com MLS evidence shows median listing price down 7.51%, active listings up 3.45%, and price reductions on 26% of listings; these are asking-market measures, not closed-sale prices or proof of buyer demand. Net migration was 2,818, while inbound mover average AGI exceeded outbound by $18,649, a calculation from the supplied mover averages. Annual QCEW covered employment grew 1.14% and average covered-worker wage grew 3.14%; these are workplace jobs and covered-worker averages, not resident employment or unemployment. Investors represented 6.52% of 3,926 purchase mortgages, limiting the evidence for dominant investor competition.
The main underwriting limit is missing property-level evidence. The modeled annual building-value loss ratio is 0.16%, and inland flood is the dominant hazard, but the model cannot establish a parcel’s flood zone, elevation, drainage, insurance price, deductible, or coverage. Closed-sale comparables, lease comps, vacancy, turnover, operating expenses, capital needs, financing terms, and assessed-value history are not published. Those gaps prevent converting gross yield into net yield or cash flow and prevent using county migration and employment to validate a particular submarket. Next checks should focus on hazard and insurance records, signed lease evidence, full operating statements, and closed sales.
