Homes Under $400K in Dallas County (2026 Guide)
With the DFW median home price sitting around $410,000–$415,000 in 2026, a $400K budget is right at the edge of "typical" — which means where you look matters a lot. Some Dallas County submarkets sit comfortably below that number with real inventory to choose from; others put you priced out entirely. Here's where a sub-$400K budget actually works in 2026, and what to expect in each area.
The Big Picture
Dallas County's overall median has been reported anywhere from roughly $270,000 to $430,000 depending on the data source and whether it's measuring Dallas city proper versus the broader metro — a reminder that "Dallas" as a search term covers a huge range of submarkets with very different price points. The honest takeaway: a $400K budget is workable across a meaningful chunk of Dallas County, but you'll need to be strategic about where you look.
The good news for buyers right now: DFW has shifted into a more balanced market. Bidding wars are rare, sellers are more open to concessions, and buyers have more negotiating leverage than they've had in several years — which matters just as much as the price tag itself when you're working with a firm budget.
Where Your $400K Goes Furthest in Dallas County
Mesquite
Median home price around $275,000. One of the most affordable suburban options in the county with reasonable access to Dallas via I-30 and I-635. A $400K budget here opens up larger homes, more updated properties, and real selection rather than compromise.
Garland
Median home price around $297,000. Similar value proposition to Mesquite — established neighborhoods, solid commute access, and a $400K budget puts you well above the median, giving you real choice in condition and lot size.
Southeast & East Dallas
Pleasant Grove & surrounding areas. Some of the most affordable pricing within Dallas city limits itself. Worth noting this is also where rental rates run lowest in the city — a sign of the broader value proposition in this part of town.
Balch Springs & Seagoville
Smaller, quieter communities with pricing generally below the county median — good options if commute flexibility matters less than budget.
Where $400K Is Tighter (But Still Possible)
Richardson
Anchored by the Telecom Corridor and UT Dallas, offering a mix of mid-century homes with strong resale value. $400K is workable here, particularly for smaller or older homes, though you'll have less room than in Mesquite or Garland.
Far North Dallas
Stretches toward the Plano border along US-75, with newer inventory and suburban density at lower per-square-foot pricing than close-in North Dallas. $400K can work here depending on the specific pocket and property age.
Lake Highlands
Popular with families for strong schools and relative value compared to pricier nearby neighborhoods like Preston Hollow — $400K is achievable but competitive, especially for updated homes.
Where $400K Generally Doesn't Stretch as Far
Preston Hollow, Park Cities-adjacent areas, and much of Uptown/Downtown Dallas sit well above this budget for anything beyond a smaller condo or townhome. If your heart is set on these areas, $400K will mean a real compromise on size, condition, or property type — worth knowing upfront rather than discovering it after several disappointing showings.
Don't Forget: Property Taxes Change Your Real Budget
This matters more in Texas than almost anywhere else. Dallas County's effective property tax rate runs around 2.0–2.5%, meaning a $400,000 home carries roughly $8,000–$10,000/year in property taxes before exemptions — a real number that affects your monthly payment as much as the purchase price itself. The good news: recent legislation increased the general homestead exemption to $140,000, which meaningfully reduces the school-tax portion of that bill once you file for it after closing (and you should, immediately — it's not automatic).
Budgeting for taxes alongside price is especially important when comparing homes across different cities within the county, since rates and school district portions can vary between neighboring suburbs.
What a $400K Budget Actually Buys Right Now
At current mortgage rates in the low-6% range, a $400,000 home with 20% down runs roughly $2,400–$2,600/month in principal and interest alone, before property taxes and insurance are factored in. Combined with Dallas County's tax rate, all-in monthly payments in the $3,000–$3,200 range are realistic for a $400K purchase — worth running your exact numbers with a lender before you start touring, so you know precisely what price range to search within.
Bottom Line
$400K in Dallas County goes considerably further in Mesquite, Garland, and southeast Dallas pockets than it does closer to the urban core or in North Dallas's more established neighborhoods. With the market currently favoring buyers more than it has in years, this is a genuinely good window to find real value if you're flexible on location — the key is matching your must-haves (commute, schools, lot size) against where your specific budget actually clears the local median.
