Texas Home Affordability Calculator: Property Tax, Insurance & California Comparisons Explained

A Texas home affordability calculator has to include more than the mortgage payment — it needs property tax (often around 1.4% of home value annually), homeowners insurance ($350 or more per month in many areas), and utilities, because the savings from no state income tax can be partly or fully offset by these higher ongoing costs. If you're moving from California, running the full equation before you fall in love with a listing will save you a surprise later.

Why "No State Income Tax" Isn't the Whole Garden

California transplants often hear "Texas has no state income tax" and assume the rest follows naturally — lower bills, more house, easier math. But a garden needs more than good soil; it needs water, sunlight, and the right pot size too. Texas makes up for the missing income tax through higher property taxes and, in many regions, pricier insurance. The soil is different, not necessarily richer.

Property Tax: Texas's Biggest Line Item

In California, Proposition 13 generally keeps property tax assessments low and predictable. In Texas, there's no equivalent cap on the rate itself, and effective property tax rates commonly land near 1.4% of assessed value — sometimes higher depending on the county and local school district. On a higher-priced home, that line item alone can rival or exceed what a Californian paid in state income tax the year before. It's baked into the monthly mortgage payment through escrow, so it shows up every single month, not just at tax time.

Homeowners Insurance: Why Texas Premiums Run Higher

Texas sits in hail alley and hurricane territory, which pushes homeowners insurance premiums up — often $350 or more per month depending on the home's location, age, and roofing material. Coastal and North Texas buyers in particular should budget generously here. This is a cost many California buyers underestimate, since insurance in parts of California can run lower for comparable home values (wildfire zones being the notable exception).

Utilities and the Hidden Water Bill

Texas summers mean air conditioning runs longer and harder, and utility costs can climb accordingly. Some municipalities also have separate water, sewer, and trash fees that aren't always folded into one bill the way certain California cities structure things. None of these are deal-breakers — they're just additional rows in the spreadsheet that deserve a seat at the table.

Building Your Own Affordability Calculator

Think of your affordability calculator like a raised garden bed — every plank matters, or water leaks out the sides. A complete monthly picture should include:

• Principal and a loan payment structured around your goals (programs subject to qualification)
• Property tax, estimated near that 1.4% range but verified for your specific county
• Homeowners insurance, quoted for the actual property, not a regional average
• HOA dues, if applicable
• Utilities and water/sewer fees
• What you would have paid in California state income tax, as your "savings" baseline

Add it all up on both sides — the California scenario and the Texas scenario — before comparing. The no-income-tax benefit is real, but it's one plank in the bed, not the whole structure.

Comparing the Full Payment: California vs. Texas

For many California buyers, the full Texas monthly housing cost — mortgage, tax, insurance, utilities — ends up lower than a comparable home in coastal California, even after accounting for higher property tax and insurance. For others, especially those eyeing higher-value homes in insurance-heavy counties, the gap narrows considerably once every line item is counted. The honest answer is: it depends on the home, the county, and your income level, which is exactly why running your own numbers matters more than a general rule of thumb.

Our Texas resources break down regional differences in property tax rates and insurance trends so you're comparing real soil conditions, not just a sales pitch about sunshine and no income tax.

Planting Roots with a Clear-Eyed Plan

As a mortgage brokerage, Plan Prepare Home doesn't lend the money directly — we shop multiple lenders on your behalf to find loan structures that fit your actual numbers, not just a headline comparison between two states. If you're relocating from California to Texas, we can help you map out property tax estimates, insurance ranges, and the loan programs available to you (again, subject to qualification), so the only surprises left are the good ones — like finally having room for that garden you've been dreaming about.
