How to Source Off-Market Infill Lots in Houston, DFW, and Austin
When it comes to building profitable housing projects in Texas, one of the most overlooked but lucrative strategies is sourcing off-market infill lots. These underutilized or vacant parcels—often hidden within growing urban neighborhoods—present prime opportunities for developers, investors, and Texas land buyers looking for high returns. Whether you're active in Houston, Dallas-Fort Worth (DFW), or Austin, understanding how to find and acquire these properties can set your development pipeline apart.
In this blog post, we’ll break down the land acquisition strategy in Texas, explore the tools and tactics to uncover off-market deals, and show you how to position yourself as a go-to Texas builder with access to prime land in Texas’ top metros.
What Are Infill Lots and Why Are They Valuable?
Infill lots refer to vacant or underused parcels of land located within already-developed urban areas. These lots are typically surrounded by existing infrastructure—utilities, roads, schools, and amenities—which significantly lowers development costs compared to rural land acquisition.
The demand for urban housing continues to climb, particularly in fast-growing regions like Houston, DFW, and Austin. As a result, developers are aggressively pursuing Texas land development opportunities that allow them to build inside city limits without the lengthy and costly process of raw land development in suburban fringe areas.
Key advantages of infill lots include:
Faster entitlements and permitting
Higher density potential
Strong resale or rental demand
Lower infrastructure costs
Proximity to urban amenities
The Challenge: Finding Off-Market Infill Lots
The Texas real estate market is highly competitive, and MLS-listed infill lots are often overpriced or picked over. To gain a real edge, smart investors and Texas land developers focus on sourcing off-market land in Texas—properties not publicly listed for sale.
These off-market deals are typically owned by long-time property holders, distressed sellers, tax delinquent owners, or heirs who have inherited unused parcels. The good news? Many of them are open to selling—you just need to know where to look and how to approach them.
Why Focus on Houston, DFW, and Austin?
These three metros represent the most active and fastest-growing housing markets in Texas. Here’s why each is an ideal target for your land acquisition strategy:
Houston
Houston offers a deregulated zoning environment, which allows developers greater flexibility. It's a vast metro with many overlooked urban pockets ideal for infill development. Neighborhoods like Third Ward, Near Northside, and Acres Homes are seeing rapid transformation and offer Texas land investment potential with significant upside.
Dallas-Fort Worth (DFW)
DFW is one of the top real estate markets in the country. As urban core areas like Oak Cliff, East Dallas, and South Dallas undergo revitalization, there are numerous opportunities to acquire infill lots for development. Demand from Texas builders in DFW is especially strong.
Austin
Austin’s tech-driven growth has fueled major housing demand. East Austin, Montopolis, and South Austin still contain scattered vacant parcels and underutilized lots. Zoning reform efforts also make it a favorable location for subdivision development in Texas.
1. Build a Targeted Off-Market List
The first step in sourcing off-market infill lots is to build a targeted list of properties. Use these tools and data sources:
a. County Appraisal District (CAD) Data
Pull ownership and land use data from your metro’s CAD. Search for vacant land zoned residential or commercial within city limits. Filter by lot size, zoning code, and ownership type.
b. GIS Mapping Tools
Many Texas counties offer GIS maps that allow you to visually identify vacant parcels, public easements, lot configurations, and neighborhood characteristics. This helps pinpoint buildable infill lots.
c. Code Violation Lists
Property owners with ongoing code enforcement issues are often motivated sellers. Contact local code enforcement or public works departments to obtain lists.
d. Delinquent Tax Records
Target owners who are behind on taxes. These sellers are often more open to off-market offers, especially if the lot isn’t producing income.
2. Skip the MLS—Use Direct Outreach Instead
Most prime land in Texas won’t be found on the MLS. Direct-to-seller outreach remains one of the most effective methods to land deals at a discount. Here's how:
a. Cold Calling and Texting
Skip realtors and talk directly to property owners. Use tools like BatchLeads, PropStream, or REIPro to skip trace owner information and launch cold calling or SMS campaigns.
b. Direct Mail
Old-school still works. Send postcards or letters to targeted owners explaining that you’re a Texas land buyer interested in purchasing their lot as-is, with cash, no commissions, and fast closing.
c. Door Knocking
Especially effective in tight-knit neighborhoods or historic districts. Personal contact creates trust and shows commitment.
d. Referral Network
Build relationships with local surveyors, city planners, and code inspectors. These professionals often hear about off-market land opportunities before anyone else.
3. Evaluate the Development Potential
Not every infill lot is a winner. Before making an offer, evaluate the site’s development feasibility:
a. Zoning and Land Use
Check current zoning codes and confirm allowable uses, minimum lot size, setbacks, and height restrictions. Use tools like MuniCode or city zoning maps.
b. Access to Utilities
Ensure that water, sewer, and electricity are available at or near the site. Development in areas without existing utility access is often cost-prohibitive.
c. Lot Configuration
Narrow or oddly shaped lots may require variances or design workarounds. Flag these early in the acquisition process.
d. Flood Zones and Environmental Concerns
Use FEMA flood maps to avoid high-risk zones. Environmental issues can derail or delay your Texas land development project.
4. Create a Repeatable System
Once you’ve identified a few successful deals, scale your process with systems. Consider building a land acquisition funnel:
Weekly lead pulling from your data sources
Skip tracing and outreach automation
CRM to track communication and follow-ups
Contract templates and purchase protocols
Relationships with local Texas builders and GCs to offload deals quickly
As your pipeline grows, you may also consider entitling land in Texas before resale, adding significant value through minor subdivisions, zoning changes, or permitting.
5. Partner with Builders and Investors
Once you've acquired a few infill lots, you can flip them to Texas builders looking for ready-to-go lots, or joint venture on small builds. Builders love working with land acquisition specialists who bring them shovel-ready sites.
Networking with Texas real estate development firms, attending investor meetups, and reaching out to small and midsize builders in your market can open doors. Some builders may even pay a premium for access to consistent off-market lot deals in target neighborhoods.
6. Understand Local Incentives and Growth Corridors
Municipalities like Houston, Dallas, and Austin often have incentive programs aimed at urban infill and affordable housing development. These programs can include:
Reduced permitting fees
Tax abatements
Density bonuses
Land bank opportunities
Additionally, stay informed about Texas growth corridors—areas where infrastructure investment is pushing urban boundaries. Buying infill land near future transit, school expansions, or commercial developments can provide a significant upside.
Conclusion: Off-Market Infill Lots Are the Future of Urban Development in Texas
If you want to succeed in today’s competitive real estate market, learning how to source off-market infill lots in Houston, DFW, and Austin is a must. These lots are the hidden gems of Texas land acquisition, offering faster ROI, lower infrastructure costs, and access to growing urban demand.
By building a data-driven acquisition system, focusing on local market knowledge, and building relationships with Texas builders and developers, you can become a go-to source for prime land in Texas. Whether you’re flipping lots, entitling raw land, or developing small subdivisions, this strategy is key to long-term success.
