Best DFW Suburbs Under $400K (2026): Where You Can Still Buy a House

There is still a version of North Texas where an ordinary household income buys an ordinary house. It has moved, but it has not disappeared, and it is worth knowing exactly where it went.

What follows is a map of it. Not a ranking, because the right answer depends almost entirely on where you work and what you are willing to drive. Prices move, so treat every figure here as a shape rather than a quote and check the current reality before you plan around it.

Where the $400K Line Actually Falls

Three broad categories still clear it, and they are genuinely different products:

• New construction, thirty-five to fifty minutes out. The northern Collin County towns and the eastern corridor. New house, new street, no trees, longer drive.
• Established housing, fifteen to thirty minutes out. Garland, parts of Rowlett, Lewisville, older Carrollton. 1970s to 1990s stock, mature trees, shorter commute, renovation budget required.
• Townhomes and smaller detached homes in the core. Less square footage, better location, and in some cases an HOA doing the maintenance.

What has effectively left this price band is a new detached house inside Frisco, Plano, Allen, Coppell or Flower Mound. That is the trade the rest of this post is about.

What You Are Trading for the Price

Being explicit about this is more useful than a list of cities. You are trading one of four things:

1. Time, in the form of commute, which is the most common trade and the most underestimated.
2. Condition, in the form of a renovation you will pay for over the next five years rather than in the purchase price.
3. Space, in the form of a townhome or a smaller lot closer in.
4. Maturity, in the form of a town where the schools, roads and retail are still being built around you.

None of these is a bad trade. All four are bad trades if you make them without noticing. The people who are unhappy two years later are almost always the ones who priced the house and not the trade.

The Northern Corridor: Anna, Melissa, Princeton

US 75 north of McKinney is where most of the affordable new construction in Collin County ended up. All three towns share a profile: brand-new housing, rapidly growing school districts, tax rates that reflect the cost of building infrastructure quickly, and a commute that is genuinely long if your job is in Dallas.

• Anna has the most new inventory and the most consistent pricing, with a fast-improving retail base.
• Melissa is smaller, with a district that has grown extremely fast from a small base and has invested heavily in new campuses.
• Princeton has been the lowest entry price in the county for several years and is also the town that most publicly hit the brakes on new permitting to let infrastructure catch up. Both facts matter to a buyer.

The single most important thing to check in all three: whether the specific subdivision carries a PID assessment. It is common in this corridor and it can add a material amount to the annual tax bill for decades.

The Eastern Corridor: Lavon, Farmersville, Royse City

SH 78 and the I-30 corridor east of the lakes are the other direction the affordability went, and it is less well known than the northern one, which occasionally makes it better value.

Lavon went from a few hundred houses to a real market in under a decade and sits on the lake. Farmersville is a genuine small town with an actual main street, now inside the path of growth. Royse City sits over the Rockwall County line on I-30, which is a real commuting advantage over the SH 78 towns if your work is east or south.

Common thread: these are places where you are buying ahead of the infrastructure rather than after it. That is a legitimate strategy and it has a specific risk, which is that the timeline for the road, the school and the grocery store is not under your control.

The Inner Ring: Garland, Rowlett, Lewisville

The alternative strategy, and the one I think is underrated. Rather than buying a new house far out, buy an older house close in and spend the difference on updating it.

• Garland is large and varied, with genuinely good 1970s and 1980s stock on real lots with mature trees, and rail access.
• Rowlett puts you on Lake Ray Hubbard with a DART station, at prices well below anything comparable on the north side.
• Lewisville is the best-connected option on this list for anyone working the airport corridor or the northwest side.

What you take on is age. Roofs, HVAC systems, cast iron plumbing in the oldest stock, and foundations in clay. All of it is manageable and all of it should be budgeted rather than discovered. Start with what an inspection covers.

The Costs That Do Not Show in the Price

Four things that can quietly erase the saving, in rough order of how often they do:

The tax point deserves emphasis because it is the one people never model. How the rates compare across DFW cities is worth reading before you narrow your list, not after.

How to Choose Between Them

Three questions, in this order, and they eliminate most of the list quickly:

1. Where do you actually have to be, and how often? Fully remote opens the entire northern and eastern corridor. A daily drive to downtown Dallas closes most of it.
2. New or updated? These are different purchases with different risk profiles. New construction has warranty coverage and no deferred maintenance but comes with builder-contract dynamics that are not the standard TREC form. Older stock is the opposite on both counts.
3. What is your reserve after closing? Thinner reserves argue strongly for newer construction. A 1985 house with $2,000 left in the bank behind it is a stressful way to live.

Run your real number through the affordability calculator before you fall in love with a city, and use the neighborhood matcher to weight commute against everything else. The broader framing on choosing a city is in how to choose a North Texas city.
