What Your Realtor Needs to Know When You're Buying a Lot to Build Your Dream Home

Buying a lot is nothing like buying a house. There's no inspection contingency checklist that covers what actually matters. There's no comparable sale that tells you whether the soil will support the foundation you're planning. There's no listing photo that shows you where the water goes when it rains. Most realtors are trained to sell existing homes. Representing someone who wants to buy raw land and build on it requires a completely different set of skills — and the gap between those two things is where buyers get hurt.

1. How to Evaluate a Lot — Not Just Price It

There is a difference between what a lot costs and what it will cost you to build on it. That difference can be $10,000. It can also be $80,000. A realtor with construction experience walks a lot looking at soil conditions, drainage, slope, utility access, and buildable footprint. They're not just evaluating the purchase price — they're evaluating the total cost of ownership before a single permit is pulled.

2. North Texas Soil — Gumbo Clay Is Real

DFW sits on some of the most expansive clay soil in the country. An experienced agent knows to recommend a geotechnical soil test before closing, not after. Foundation pier requirements driven by poor soil conditions can add $15,000–$30,000 to a build before framing begins. That cost belongs in your purchase price negotiation, not your construction budget surprise.

3. Utilities — 'Available' Is Not 'Connected'

Your agent should be calling the utility providers before you make an offer. Water, sewer, electric, and gas each need to be confirmed at the lot line. Extensions can run $10,000–$50,000+ and they're your responsibility as the buyer. An agent who doesn't know to ask this question is leaving real money on the table.

4. Zoning, Setbacks, Easements, and Flood Zones

This is public record — but someone has to look. Building setbacks determine how close you can build to property lines. Utility easements can't be built over. A FEMA flood zone designation affects your insurance, your lender, and sometimes what you're permitted to build at all. An agent with land experience finds these in 20 minutes. An agent without it finds them after you've already fallen in love with the lot.

5. The Contract Contingency Conversation

Every offer on raw land should include a due diligence contingency — the ability to exit the contract if the soil test, perc test, utility investigation, or zoning review reveals a problem. An agent who doesn't initiate this conversation is leaving you exposed. This isn't a technicality. It's the most important clause in a land purchase contract.

6. Understanding the Build Process After Closing

Your realtor should understand what comes next — permit timelines in McKinney versus Frisco versus Prosper, how long site prep takes, what a realistic build timeline looks like, and how to select a builder who will actually protect your budget. If your agent has never been involved in a custom build, their guidance stops at the closing table.

The Questions to Ask Before You Hire a Realtor for a Land Purchase

• Have you personally represented clients through a lot purchase and custom build?

• Can you walk this property and identify the due diligence items I need to complete before closing?

• Do you have relationships with geotechnical engineers, civil engineers, and builders in this area?

• What contingencies would you put in the contract to protect me?

• What does the build process typically look like after lot closing in this market?
