When you buy a house, most of what you need to know is already established. Somebody has already proven the land could be built on. The water arrives. The wastewater leaves. There is a driveway, and the right to use it.
On raw land, none of that is settled. You are not buying a home — you are buying the possibility of one, and that possibility depends on conditions you cannot see from the road.
This is the checklist we work through with buyers before they commit to a homesite anywhere in the Austin area — from Bee Cave and Lakeway out to Dripping Springs. Work through it and you will either buy with confidence or walk away early, which is the cheaper outcome of the two.
Water: where does it come from?
The first question on any Hill Country lot. There are broadly two answers, and they lead in different directions.
A utility connection. Some lots sit inside a water utility’s service area. If that is the case, confirm in writing that the provider will actually serve this parcel, and what has to happen physically to connect it. Being inside a boundary on a map is not the same as having a tap at the property line.
A well. If the lot is served by a private well, or would need one, find out whether a well already exists and whether it has a completion report on file. Ask what neighbouring wells encountered — depth and yield vary considerably across short distances in this region. Much of the Austin area falls within a groundwater conservation district, and districts have their own permitting requirements. Identify which district the parcel sits in and ask them directly what applies. Do not assume the rules are the same as the next county over.
Wastewater: can it take a septic system?
If there is no sewer connection, the property needs an on-site sewage facility — a septic system. Whether it can have one is a soil and site question, answered by a licensed site evaluator, not by the seller and not by your agent.
Ask whether a soil evaluation has already been done. If it has not, that evaluation is one of the most important things you can pay for during your option period. The result determines what type of system is required, where it can go, and how much of your lot it consumes — which in turn constrains where the house can sit.
Permitting runs through the county or the local authorised agent. Find out which one has jurisdiction before you are under contract.
Access: can you legally get to it?
A lot that touches a road is not automatically a lot you can drive onto.
Confirm how the parcel is legally accessed — a public road frontage, or a recorded easement across someone else’s land. If it is an easement, your title company should identify it and you should read it: easements can specify width, permitted use, and who maintains the surface. If access depends on a shared private road, ask who currently maintains it and under what arrangement.
Your title commitment is the document that surfaces this, and your surveyor confirms it on the ground. If access is unclear, that is a question for a real estate attorney before you remove your contingencies — not something to resolve on a handshake with a neighbour.
Slope, rock and buildable area
Acreage is not the same as usable acreage.
Walk the lot. Look at where it falls away, where water would run during a heavy rain, and where the ground is solid enough to hold a foundation. Hill Country lots frequently have significant grade and shallow soil over rock, both of which affect what a foundation and a driveway will require.
Check whether any part of the parcel sits in a mapped floodplain. FEMA flood maps are public and your agent should pull them for any lot you are seriously considering. A floodplain does not necessarily disqualify a lot, but it changes where you can build and it changes the insurance conversation.
Ask about tree protection too. Several jurisdictions in the Austin area regulate the removal of larger or heritage trees, and those rules can affect your building envelope.
Utilities at the boundary
Electricity, and increasingly internet, are worth confirming before you fall in love with a view.
Find out how far the nearest electric service is and who the provider is. Extending service across a long distance is a real cost and it is borne by you, not the seller. Ask the provider directly what the process involves for that specific parcel.
For internet, check what is actually available at the address rather than what is advertised for the area. If you intend to work from the property, do this before you write an offer.
Deed restrictions and any property owners’ association
Most platted subdivisions carry recorded restrictions, and many Hill Country developments have an owners’ association.
Get the recorded documents and read them. They can govern minimum and maximum house size, materials, roof pitch, outbuildings, livestock, short-term rental, how long you have to begin construction after purchase, and whether you may subdivide later. Buyers are frequently surprised by the construction-timeline clause in particular.
If a restriction matters to your plans, have a real estate attorney read it before you remove contingencies. Your agent’s job is to make sure you have the documents and understand which ones need professional review; interpreting them is the attorney’s job.
Survey
Ask whether a current survey exists. If it does, read it against what you have been told — surveys reveal encroachments, easement locations, and whether the fence line is actually the property line. It often is not.
If no current survey exists, get one. On raw land it is not an optional formality.
What your agent should be doing
If you are working with a buyer’s agent on a homesite purchase, they should be pulling the flood maps, obtaining the recorded restrictions and any association documents, identifying the groundwater district and the septic permitting authority, coordinating with the title company on access and easements, and building an option period long enough for the soil evaluation to come back before your contingencies expire.
That last point matters more than any other on this page. Most land deals that go wrong go wrong because the buyer ran out of option period before the diligence came back.
Frequently asked questions
How is buying land different from buying a house?
On a house, the questions of whether it can be built on, served with water, and connected to wastewater have already been answered. On land, none of them have. The diligence moves from inspecting a structure to verifying that a structure is possible.
Do I need a real estate agent to buy a lot?
Not legally. Practically, land transactions have more ways to go wrong than resale purchases, and the listing agent represents the seller. An agent representing you coordinates the survey, the soil evaluation, the title review and the restriction documents, and structures the option period so the answers arrive before your contingencies expire.
What is the single most common mistake?
Too short an option period. Soil evaluations, survey work and utility confirmations all take time, and a standard option period is often not long enough for land. Negotiate that up front.
Can I get a mortgage on a lot?
Financing raw land works differently from financing a house, and the products available differ from lender to lender. Speak to more than one lender early, before you are under contract, so you know what your options look like for the specific parcel.
Do I need a survey if the seller has an old one?
Read the old one, but treat it as information rather than as a current representation. Boundaries, improvements and easements change. On raw land a current survey is worth having.
What if the lot is in a floodplain?
It is not automatically disqualifying, but it constrains where you can build and it affects insurance. Have your agent pull the FEMA map for the parcel and factor the answer in before you write an offer.
