The 78704 Land Value Report: What Infill Lots Are Actually Worth in 2026

78704 Seller Strategy  ·  May 2026

If you own an older home in 78704 and you have noticed the new construction going up on your street, you are asking the right question: what is my lot actually worth to a builder? It is a fundamentally different question than what your house is worth on Zillow. Zillow is pricing the structure. A developer is pricing the dirt.

This post gives you real numbers — drawn from actual transactions in the submarket — and explains what drives land values in Barton Hills, Zilker, Travis Heights, and Bouldin Creek. If you are sitting on a property built before 1990 in this zip code, you may be holding more value than you realize.

Why 78704 Is Ground Zero for Austin Infill

South-central Austin has been the city's most consistently in-demand submarket for the better part of a decade. The reasons are not complicated: walkability to South Congress and South Lamar, Barton Springs a mile away, Lady Bird Lake nearby, and an urban lifestyle you cannot recreate in a master-planned suburb.

The problem is there is almost no vacant land left. Every buildable lot that comes to market gets absorbed quickly, and the path to new luxury product increasingly runs through teardowns. Builders who want to deliver a $2M+ home in 78704 need to buy an old house first and remove it — which means they are paying land-plus-demo prices for the privilege. For homeowners, that dynamic creates leverage. The question is knowing how to use it.

How Lot Value Is Calculated in This Submarket

Developers and builders underwrite land using a backwards math approach: they start with the exit price (what the finished home will sell for), subtract construction costs, profit margin, and carrying costs, and what is left is the max they can pay for dirt.

In 78704 right now, that math typically produces land values in the $75–$95 per square foot of lot area range for standard residential parcels. But that number moves significantly based on several factors outlined below.

Street-Level Breakdown by Neighborhood

Land values are not uniform across 78704. Here is how the three core sub-neighborhoods are trading right now.

Barton Hills commands the premium end of the 78704 land market. Proximity to Barton Springs Pool, greenbelt trail access, quiet residential character, and the concentration of high-end new construction has pushed lot values to the $82–$95/SF range on well-positioned parcels. The strongest lots are on elevated streets with Greenbelt adjacency or views, and oversized lots (8,500 SF+) that allow larger finished square footage.

Zilker sits in a similar tier to Barton Hills — arguably with even stronger walkability to Barton Springs and the trail system — and lot values reflect it. Recent transactions have landed in the $80–$92/SF range for properties that pencil well for new construction. The concentration of 1950s and 1960s ranch-style homes makes Zilker particularly active for teardown activity.

Travis Heights and Bouldin Creek tend to trade at a modest discount to the Barton Hills/Zilker core — typically in the $72–$85/SF range. That said, South Congress-adjacent blocks in Bouldin and the elevated sections of Travis Heights have seen strong builder activity, and best-in-class lots in those areas have traded at the higher end of that range.

What Builders Are Actually Paying: Recent 78704 Comp Data

The Davis Agency has executed six off-market transactions in 78704, all sold directly to our builder and developer network. Here is how those deals actually landed.

All six transactions were completed privately — no MLS listing, no open houses, no public marketing.

The Variables That Move the Number

Lot size and geometry. Wider lots with clean rectangular shapes allow better architectural layouts. Odd shapes, narrow frontages, or irregular setbacks compress value because they limit what the builder can deliver.

Topography. Flat, level lots or those with buildable elevation and views are more valuable than lots with severe grades that require engineered foundations and extensive site work. The cost difference can run $80,000–$150,000 in construction, and builders price that risk into their offer.

Tree canopy. Austin's heritage tree ordinances are real. A lot with a protected 24" oak in the center of the buildable area significantly limits the floor plan. Builders know how to work around trees, but they discount for the constraint.

Utility connections and site access. Already-connected water, sewer, and electrical reduce soft costs. Alley access can add flexibility for garage placement and increase effective livable square footage.

Immediate comparables. If a builder has already completed a new build on the same street and it sold at $2.4M, they will pay more for the adjacent teardown than they would on a block with no recent new construction data.

Whether it is on-market or off-market. A property listed on MLS attracts competing bids — but also less-qualified buyers, longer due diligence periods, and public pricing that can reset neighborhood comps in ways sellers do not always want. Off-market transactions move faster and often net more, because motivated buyers pay for certainty.

What This Means for 78704 Homeowners

If you own a home built before 1985 in Barton Hills, Zilker, Travis Heights, or Bouldin Creek, it is worth getting a proper land valuation — not a Zillow estimate, and not a generic CMA from an agent who works across 30 zip codes.

The right analysis looks at your specific lot dimensions, the impervious cover calculation, the builder activity on your immediate block, and the current demand from the 10–15 builders and developers actively acquiring in this submarket right now. That is the analysis we run for every 78704 owner who reaches out. It takes about 48 hours, costs you nothing, and often reveals a number that surprises people.

Frequently Asked Questions

Do I have to list my home to sell it as a teardown?
No. The majority of teardown and infill lot transactions in 78704 happen off-market. Sellers avoid the disruption of public showings, and buyers — typically builders and developers — prefer the certainty of a direct negotiation.

Does the condition of my house affect the land value?
In most cases, minimally. Builders are demolishing the structure regardless. Severe functional or environmental issues (foundation failure, underground storage tanks, significant asbestos) can create additional carrying cost that a buyer will price in — but a house that simply needs updating is not a meaningful discount factor.

What is the timeline for an off-market teardown sale?
Typically 30–60 days from initial offer to close when working with an experienced builder buyer. Compared to a 60–90 day traditional listing process plus contingencies, it is a meaningful difference.

Can I sell and stay in my home through closing?
Yes. A leaseback provision after closing is common in off-market teardown deals when the seller needs transition time. A proper transaction structures for that.

What zip codes near 78704 have similar land dynamics?
78703 (Tarrytown, Clarksville) and portions of 78745 (South Congress corridor) have active infill markets, but land value per SF is generally lower than the 78704 core. 78746 (Westlake Hills) has a different dynamic — larger lots, different builder economics, and lower land value per SF due to size.
