What should you know about buying land in Southern Idaho?

Buying land can be a significant investment, and there are several factors to consider before making a purchase. Here are some things you should know:

  1. Location:
    Consider the location of the lot carefully. Is it in a desirable area? Is it close to amenities like schools, shopping centers, and transportation? Is it in a flood zone or on a steep slope? Check local zoning regulations to ensure that you can build the type of home you want on the land.

  2. Size and Shape:
    The size and shape of the land or building lot will impact the type of home you can build. Ensure that the lot is large enough to accommodate the home you want to build and any other features you desire, such as a garden or outdoor living space. A building lot that is too narrow or oddly shaped may limit your options

  3. Fencing is an additional expense. 

    Many times clients want horses or cattle and have a little ranchette. They want to start from scratch and develop the land and build their dream including horses and cattle. The final step of this dream is putting fence around the property. Any idea how much it costs to put a fence to hold the cattle in safely? It is a lot to fence about 10 acres. that is nearly a quarter of a mile of rails or barbed wire fence.

  4. Utilities:
    Ensure that the land has access to all the utilities you will need, such as water, sewer, electricity, gas, and telephone/ internet. If not, you may need to pay for installation or connection fees.

  5. Topography:
    The lot's topography can impact the cost and complexity of the building. A sloping lot may require grading or retaining walls, which can add to the construction costs which can be costly based on how far it is to access points. Also, in Boise for example, there are foothill construction ordinances that must be followed.

  6. Soil and Geology:
    Understanding the soil and geology of the lot is important, as it can impact the cost and design of the foundation. Soil testing can reveal the type of soil and the presence of any contaminants. Aks a local Land engineer about soils test and engineering cost to make the site buildable.

  7. Restrictions and Regulations:
    Check for any local restrictions or regulations that may impact the design or construction of your home. This could include zoning regulations, building codes, or neighborhood covenants. This can include not only the exterior design but also the height of the roofline.

  8. Is there road access?

    In less developed areas, easy road access may not be available. Land in the mountains may only be accessible by vehicles with high ground clearance and four-wheel drive, which can make access difficult. If the land is far enough away, the county may not maintain the road, which will take more time and money to grade and pave the road to make it passable.

    Sometimes, there you may have to pass through a neighbor’s property to get to yours. In this case, an easement may need to be drawn up to show you can use their land to get to yours. With the easement, you and your neighbor will have to reach an agreement to determine who maintains the road to get to your land via theirs.

  9. Professional Help:
    Consider working with a real estate agent, land surveyor, architect, or builder to help you navigate the process of buying a building lot and designing and building your home.

By carefully considering these factors, you can make an informed decision when buying a building lot and set yourself up for a successful home construction project.
