Buying land to build a mountain home is rewarding and complicated. There is nothing quite like designing a home around a view you chose yourself, positioning the porch to catch the sunset and building exactly what you want. But a lot that looks perfect on a walk-through can hide challenges that affect whether, where and how you can build. Doing your homework before you buy protects your budget and your dream.
Here is what to check before you buy a mountain lot, how to plan your due diligence and the mistakes to avoid.
Why Land Requires More Homework Than a House
When you buy an existing home, much of the hard work has already been done. The septic system is installed, water is available, the driveway is built and the home has passed permitting. When you buy raw land, you are taking on all of those questions yourself. In the mountains, steep slopes, rocky soils, long access roads and the distance to utilities can make some lots expensive or impractical to build on.
That does not mean buying land is a bad idea. It means you need to verify the essentials before you commit.
What to Check
Perc test for septic
Most mountain lots are not served by public sewer, so you will likely need a septic system. A percolation test, often called a perc test, evaluates how well the soil absorbs water. The results help determine whether a conventional septic system can be installed, what type of system is needed and where it can go. In Georgia, septic permits are handled through the county environmental health office. A lot that does not perc well may require a more expensive alternative system or may not support a home at all. Make your purchase contingent on acceptable results whenever possible.
Well feasibility
If public water is not available, you will need a well. Depth and yield vary from place to place, and there is no way to know exactly what you will find until a well is drilled. Talk with local well drillers about typical conditions in the area, ask neighbors about their wells and confirm that a well can be placed with proper separation from the septic system.
Access and easements
Confirm that the lot has legal access, either from a public road or through a recorded easement. Find out who maintains the access road and whether there is a road maintenance agreement. Also review any easements that cross the property, such as utility lines or a neighbor’s right of way, since these can limit where you build.
Slope and buildable area
Mountain lots can be steep. A lot with a spectacular view may have only a small area that is practical to build on, and building on steep slopes can require extensive grading, retaining walls and specialized foundations. Walk the lot with a builder or engineer, and identify where the house, driveway, septic system and well could go.
Utilities to the lot
Find out whether electricity is available at the lot line or will need to be extended, and what that would involve. Ask about internet service, especially if you work from home. If you plan to use propane for heating or cooking, confirm that delivery trucks can reach the site.
County permits and setbacks
Each county has its own permitting process and setback requirements that dictate how close you can build to property lines, roads, streams and other features. Zoning may also limit how the land can be used. If the lot is in an HOA community, there may be additional rules on home size, architectural style, materials and construction timelines.
Other Considerations
- Survey. A current boundary survey confirms property lines and identifies encroachments.
- Flood zones. Check FEMA flood maps for lots near creeks or rivers.
- Driveway costs. A long or steep driveway can be a significant expense.
- Tree clearing. Clearing for the home site, driveway and view can add cost.
- Financing. Land loans and construction loans often have different requirements than standard mortgages. Talk with a lender early.
- Timeline. Permitting, site work and construction take time.
Planning Your Due Diligence
- Write contingencies into your offer for a perc test, survey and any other key evaluations.
- Bring in a builder early to review the lot and estimate site preparation costs.
- Talk with the county about permits, setbacks and zoning.
- Contact utility providers about service to the lot.
- Review covenants if the lot is in a community.
- Get a land or construction loan pre-approval so you understand your financing options.
Common Mistakes to Avoid
- Buying a lot without a perc test
- Assuming utilities are available at the road
- Underestimating site preparation costs on a steep lot
- Overlooking easements that limit where you can build
- Ignoring HOA architectural rules
- Falling for a view without confirming the lot is buildable
Working With People Who Know the Area
Sherry works with builders and surveyors who know the area. Local professionals understand mountain soils, slopes, access issues and county requirements, and their insight can help you avoid costly surprises.
