Step-by-Step Guide: Buying Your First Home in Katy, TX

Written By Bobby Mohebbi

Everything first-time buyers need to know — from credit check to closing day — with Katy-specific market insight and Texas-unique process details

Also applies to: Fulshear • Richmond • Cypress • Tomball • Hockley • Spring

Katy, Texas is one of the most sought-after suburban markets in the Greater Houston area — and one of the best places in the country for first-time buyers. With award-winning Katy ISD schools, master-planned communities packed with amenities, and homes starting in the Mid $200,000s, it’s no surprise that Katy continues to attract families from across Texas and the nation.

The principles in this guide also apply to nearby first-time buyer markets including Fulshear, Richmond, Cypress, Tomball, Hockley, and Spring. The Texas-specific processes are the same across all these communities.

TOTAL TIMELINE AT A GLANCE: Pre-approval: 1–2 weeks • Home Search: 1–3 months • Under Contract to Closing: 30–45 days • Total: 2–5 months

STEP 1 — Financial Preparation (Start 60–90 Days Before You Want to Buy)

Check Your Credit Score

Pull your scores from all three bureaus — Equifax, Experian, and TransUnion. Remember: mortgage lenders use your middle FICO score, not the number you see in consumer apps. Minimums for Katy-area buyers:

  • FHA loan: 580 (3.5% down) — covers homes up to $541,287 (2026 limit)

  • Conventional loan: 620 minimum; 700+ for best pricing

  • VA loan (veterans): No official minimum; most lenders want 580+

  • TSAHC/TDHCA down payment assistance programs: 620 minimum

Know What You Can Afford in Katy

As of mid-2026, first-time buyers in Katy are primarily purchasing homes in the $300,000–$450,000 range, depending on community, size, and school zone. Popular entry-level communities include Elyson, Cross Creek Ranch, Young Ranch, Cane Island, and Firethorne.

Use the 28% rule as a starting point: your total monthly housing payment (mortgage principal + interest + property taxes + insurance + HOA) should not exceed 28% of your gross monthly income.

CRITICAL — KATY PROPERTY TAXES: Property tax rates in Katy vary by location but commonly run 2.2%–2.8% depending on MUD district, city, and county. On a $375,000 home, that’s $8,250–$10,500 per year — roughly $690–$875 per month added to your payment. Always calculate taxes before falling in love with a home. Ask me for the specific tax rate on any property you’re considering.

Gather Your Documents Early

Start collecting these now. Lenders need all of them to issue a pre-approval:

  • Last 2 years of W-2s and federal tax returns (all pages)

  • 30 days of recent pay stubs (all jobs)

  • 60 days of bank statements for all accounts (all pages, no gaps)

  • Government-issued photo ID

  • Social Security number for all borrowers

  • Proof of any additional income (rental, alimony, Social Security, etc.)

  • Current monthly debt obligations (car payments, student loans, etc.)

  • If self-employed: 2 years of business tax returns + YTD profit & loss statement

STEP 2 — Get Pre-Approved (Not Just Pre-Qualified)

This is the single most important step before you tour a single home. Pre-qualification is just a lender asking you a few questions. Pre-approval means they have actually verified your income, assets, and credit — and issued a written commitment letter. In Katy’s competitive market, sellers will not take your offer seriously without it.

Pre-approval tells you:

  • The exact loan amount you qualify for

  • Which loan programs you’re eligible for (FHA, conventional, VA, USDA)

  • Whether you qualify for Texas down payment assistance

  • Your estimated interest rate and total monthly payment

  • Potential issues to resolve before making offers

NEW CONSTRUCTION TIP: If you’re looking at communities like Elyson, Bridgeland, or Cross Creek Ranch, the builder will push their preferred lender — and often offer incentives (rate buydowns, closing cost credits up to $20,000) to use them. Always compare the builder’s offer against your own lender before deciding. I can help you evaluate this comparison side-by-side.

STEP 3 — Work With a Local Katy Buyer’s Agent

Katy has market characteristics that require local expertise:

  • Flood zones: Parts of Katy and Cinco Ranch have flood history. Knowing flood zone designations before you make an offer is critical — it directly affects insurance costs

  • MUD taxes: Many Katy communities sit in Municipal Utility Districts, which add an extra layer of property taxes on top of standard county/city rates

  • Builder negotiations: New construction deals require different negotiation strategies than resale

  • School zone verification: With Katy ISD, the specific campus zone for a home matters — always verify the actual school assignment, not just the general area

A buyer’s agent costs you nothing as a first-time buyer — the seller or builder pays the commission. Not having representation at a new construction site means you have zero advocate in a process where the builder’s sales team represents the builder exclusively.

STEP 5 — Make an Offer (Understanding the Texas Contract)

Texas uses a TREC (Texas Real Estate Commission) standardized contract. As a first-time buyer, here are the Texas-specific terms you must understand:

Earnest Money Deposit (EMD)

Typically 1% of the purchase price (negotiable), deposited with the title company within 3 business days of contract execution. This shows the seller you’re serious. If you close, it applies to your costs. If you terminate during the option period, it’s refunded (minus the option fee). If you breach the contract outside the option period, the seller can keep it.

The Option Period — Unique to Texas

Texas law gives buyers an option period — typically 5–10 days — during which you pay a small fee (usually $150–$400) for the unrestricted right to terminate the contract for any reason. This is your inspection window. During option period:

  • Schedule your home inspection immediately (don’t wait)

  • Review inspection report and request repairs or price reduction

  • Confirm flood zone status

  • Review HOA documents and MUD tax rate

  • If anything is wrong, you can walk away and only lose the option fee

Title Company vs. Attorney

In Texas, real estate closings are handled by title companies (not attorneys, as in some other states). Your agent or lender will recommend a title company. The title company researches the property’s history, issues title insurance, and facilitates the closing.

STEP 6 — Home Inspection (Never Skip This in Katy)

A standard home inspection in the Katy area costs $350–$550 and typically takes 2–4 hours. In the Houston metro, inspectors specifically look for:

  • Foundation: Expansive clay soil throughout the Houston area causes foundation movement. Look for cracks, sticking doors, sloping floors

  • Roof: Hail is extremely common in the Houston area. Check for damage, missing shingles, and remaining lifespan

  • HVAC: Texas summers are brutal. An older system can fail within months and cost $5,000–$15,000 to replace

  • Plumbing: Older Katy-area homes may have cast iron pipes; newer homes, PVC or PEX

  • Flood & drainage: Even outside flood zones, poor drainage can cause localized water intrusion

NEW CONSTRUCTION INSPECTIONS: Even brand-new homes have defects. In Katy’s active new construction market, a pre-drywall inspection (while walls are open) and final inspection before closing are both worth every dollar. Builders build fast — things get missed.

STEP 7 — Appraisal, Underwriting & Clear to Close

After the option period, your lender orders an appraisal ($550–$700) to confirm the home’s value supports the loan. In Katy and surrounding suburbs, comparable sales are generally plentiful, making appraisals relatively straightforward.

Underwriting then verifies everything one final time: income, employment, bank statements, and the appraisal. Do not make any financial changes during this period — no new debt, no job changes, no large deposits without documentation.

Once underwriting completes, you receive your Clear to Close (CTC). Your lender sends a Closing Disclosure (CD) at least 3 business days before closing showing your final numbers.

STEP 8 — Closing Day

Closing in Texas takes place at a title company office. The full appointment typically runs 60–90 minutes. Bring:

  • Government-issued photo ID (driver’s license or passport)

  • Cashier’s check or wire transfer confirmation for closing costs

  • Any remaining documents your lender requested

Once all documents are signed and the lender funds the loan, the title company records the deed — and you get your keys.

REMEMBER: Texas down payment assistance programs (TSAHC, TDHCA) can cover both your down payment AND closing costs — sometimes bringing your total out-of-pocket cost to near zero. See Guide 4 for full details on these programs.

First-Time Buyer Mistakes to Avoid in Katy

  • Shopping for homes before getting pre-approved — you risk falling in love with something you can’t buy, or losing it to a pre-approved buyer

  • Ignoring MUD taxes — always ask for the total effective tax rate, not just the base rate; MUDs can add 0.5%–1.5% on top

  • Going to new construction sites without your agent — once you register without representation, the builder’s policy may exclude your agent from the deal

  • Not reviewing flood zone maps — even being in a Zone X (low risk) versus Zone AE can mean a difference of thousands per year in flood insurance

  • Skipping the home inspection on new construction — “It’s new, so it’s perfect” is a very expensive assumption

  • Making large purchases or opening credit before closing — this can collapse a loan days before closing
