The dream of building a custom home in the rolling hills of Northeast Tennessee is a powerful one. You can already picture the view from your porch overlooking Johnson City, the morning fog settling in the valleys. It\u2019s a vision of peace, of something truly your own. But the path from an empty lot to your front door is paved with due diligence. The difference often comes down to the questions asked before<\/i> the land was ever purchased<\/a>.<\/p>\n

This guide is my straightforward, no-nonsense checklist. It\u2019s not meant to discourage you, but to empower you. Think of it as a conversation we might have over coffee, where I point out the things you need to see beyond the beautiful view. It\u2019s designed to equip you with the precise questions you need to ask to ensure the land you buy is truly the foundation for your dream home, not a money pit. Taking the time now to properly vet a piece of land will save you from years of frustration and unforeseen expenses. Let\u2019s walk through it together.<\/p>\n

1. What does the topography and soil tell you?<\/b><\/h2>\n

When people look at a piece of land, they often see the trees and the view. When I look at land, I see the angle of the slope and I wonder what\u2019s underneath the grass. These two elements, topography and soil, are the most fundamental and can have the biggest impact on your budget after the initial land purchase.<\/p>\n

Topography: The Lay of the Land<\/b><\/p>\n

Topography is simply the shape of the land\u2019s surface.1<\/sup><\/span> Is it flat, gently rolling, or steeply sloped? A recent property survey or a plat map will show you the exact property lines and elevation changes.2<\/sup><\/span> In our beautiful, hilly region, it’s rare to find a perfectly flat parcel of land. While a slope can provide a stunning view and the opportunity for a walk-out basement, it always comes with a higher price tag for development.3<\/sup><\/span><\/p>\n

A steep grade means more extensive and expensive earthwork.4<\/sup><\/span> An excavator will need to perform a “cut and fill,” which involves digging out dirt from the high side of the homesite and moving it to the low side to create a level building pad.5<\/sup><\/span> This requires heavy machinery, more man-hours, and sometimes, the construction of expensive retaining walls to hold the soil in place.<\/p>\n

A driveway on a steep piece of land will also be longer and costlier to install, and you have to consider drainage solutions to keep water from washing it out or flooding your garage.6<\/sup><\/span> The beautiful hillside land can easily add tens of thousands of dollars to your site preparation costs before you even begin the foundation.<\/p>\n

Soil and Perc Tests: What Lies Beneath<\/b><\/p>\n

What you can\u2019t see is just as important. The soil on your land determines two critical things: its ability to support your home\u2019s foundation and its ability to handle wastewater if you\u2019re not on a public sewer system.<\/p>\n

If the land you are considering is outside the city limits and cannot connect to a public sewer, you will need a septic system. To get a permit for one, the land must pass a percolation test, or “perc test.” A soil scientist will dig several holes on your property, fill them with water, and measure how quickly the water drains into the soil.7<\/sup><\/span><\/p>\n

If the soil is too dense with clay and drains too slowly, or too sandy and drains too fast, the land will fail the test. A failed perc test means you cannot install a conventional septic system, which could render the land unbuildable for your purposes.8<\/sup><\/span> Never, ever buy a piece of rural land without making the contract contingent on a successful perc test.<\/p>\n

Just as crucial is a geotechnical survey, or soil test. This involves taking core samples of the soil to determine its composition and stability. Some areas in our region have expansive clay soil. This type of soil acts like a sponge, swelling when it gets wet and shrinking when it dries.9<\/sup><\/span> This constant movement can crack your foundation, buckle walls, and cause endless problems. If a soil test reveals poor conditions, an engineer may need to design a more robust and expensive foundation to compensate.10<\/sup><\/span> It\u2019s a vital piece of information to have before you own the land.<\/p>\n
