$725k Houston family neighborhoods in reach
Spring Branch (Memorial HS feeder, north of I-10)
The single best fit for the report. You get the Memorial HS diploma, you stay west of 610, you’re 18 min from Energy Corridor, you’re close to Riya’s parents, and you fit your budget without a stretch. The only work is attendance-zone and floodplain discipline — non-negotiable, but doable.
Pick 2Cinco Ranch (Katy ISD)
The ‘more house, longer commute, harder schools’ option. Best value on square footage. Loses on commute (David is over budget), loses on proximity to Riya’s parents, and the HS culture is closer to pressure-cooker than Memorial HS. A real option only if a Memorial-zoned house can’t be found.
Pick 3Energy Corridor / Nottingham Forest (SBISD west)
If you find a Wilchester/Rummel-Creek-zoned home on a high-ground street with no Harvey history, this beats Top Zone #1 on commute by 10 min/day. That’s 80 hours/yr back to David. But the per-address discipline is the highest of any zone — one mistake here and you’re in a $200k repair situation.

Texas (Harris & Fort Bend counties) property tax for a $725k home
Estimated annual tax: $14,300-$17,550 on $650k (2.2-2.7% effective; Katy MUD areas higher).
- No state income tax — but property tax effective rate runs 2.2-2.7% all-in (school + county + MUD + city), among the highest in the country.
- Homestead exemption: file with HCAD/FBCAD by April 30 of the year after closing. Caps assessed value increases at 10%/yr and shaves ~$100k off school-district taxable value (Texas raised the homestead cap to $100k in 2023).
- MUD taxes (Municipal Utility Districts) add 0.5-1.0% on top in Katy, Cypress, and most master-planned communities outside Houston city limits. Always ask: ‘Is this in a MUD? What’s the rate? When does the bond mature?’
- Over-65 freeze (not relevant now, but: school taxes freeze at age 65 — useful for Riya’s parents’ planning).
- Protest your appraisal every year. HCAD over-assesses; protests succeed ~60% of the time and save $500-$2,000/yr.
- Texas’s ‘no state income tax’ marketing is real, but for owner-occupiers, the property tax claws most of it back. Net-net Texas is still tax-favorable on high incomes — just not as much as headlines suggest.
Budget rules for a $725k Houston home
- Never bid above $725k. Salary-only DTI at 41% is the line.
- Keep at least $50k liquid post-close. With three kids and hurricane season, no exceptions.
- Reject any property in FEMA AE, VE, or X-shaded (500-yr) zones — even if priced well.
- Reject any property that flooded in Harvey, Imelda, Tax Day, or Memorial Day — pull HCAD repair history and ask the seller in writing.
- Plan for the 6.75% rate we lock, not a refinance fantasy.
- Texas property tax is brutal: 2.2-2.7% effective. Always size to the all-in monthly, not the P&I.
