If you’re buying or selling on the water in Lago Vista, there’s a set of lake-specific issues that don’t come up in a typical Austin-area sale, and getting them wrong can slow down or sink a contract. Lago Vista sits on the north shore of Lake Travis in Travis County, roughly 30 miles northwest of downtown Austin, and it’s served by Lago Vista ISD. I’m Robbie English, REALTOR and Broker at Uncommon Realty, and here’s what I go through with clients on waterfront and near-waterfront properties specifically.
Septic systems and the LCRA inspection zone
Many homes on or near the water in Lago Vista run on septic rather than city sewer, and any property within 2,000 feet of Lake Travis falls under a Lower Colorado River Authority inspection requirement for its on-site sewage facility. That inspection, and the condition and capacity of the septic system itself, needs to be understood before you’re deep into a contract, not discovered during the option period. For buyers, I confirm this early. For sellers, I make sure any known issues are disclosed properly so they don’t resurface as a renegotiation later.
Dock permitting isn’t always required, but you need to know which case you’re in
Private docks on Lake Travis generally require an LCRA permit, though many smaller residential docks, roughly 1,500 square feet or less, are typically exempt. If a property has an existing dock, I verify whether it’s permitted and whether that permit transfers, since an unpermitted or non-conforming dock can become a negotiating issue once a buyer’s inspector or the buyer themselves starts asking questions.
Lake levels move, and that affects usability
Lake Travis is a managed reservoir. Levels shift with rainfall, upstream inflows, and releases from Mansfield Dam, and those swings can be significant during drought years or wet periods. That means a dock or shoreline that looks perfect on a showing day in one season can sit well back from the water, or well into it, at another point in the year. I talk buyers through what that variability actually means for day-to-day usability rather than letting a single good showing set unrealistic expectations.
Why lot type drives value more here than elsewhere
Waterfront, water-view, and interior lots can carry very different price points even within the same subdivision, and that gap is wider in Lago Vista than in most inland Austin-area markets. I build valuations that separate those categories out rather than blending them into one average, which is the only way to get a realistic number on a lake-specific property. You can read more about how I build that kind of valuation on my home worth page.

Whether you’re chasing lake access or selling a waterfront home you’ve loved for years, I’ll walk you through what’s actually driving value and what to watch for in the contract.
