Common Mistakes When Buying Land and How to Avoid Them: An Essential Guide in the U.S.
Buying land is a significant investment and, if not done correctly, can become a costly hurdle or a legal headache. Many buyers, enticed by a good price or a promising location, overlook crucial details. Given the diversity of laws and regulations at the state and local level in the United States, due diligence is absolutely critical. Here are the most common mistakes and how you can avoid them.
- Failing to Verify Zoning and Land Use
This is, without a doubt, the biggest mistake. Zoning defines what type of buildings are allowed on a specific parcel (residential, commercial, industrial), the density of occupancy, the maximum height allowed, and setbacks, which are the required distances from property lines.
The Mistake: Buying land with the intention of building a duplex or multi-family rental property, only to discover that local regulations only allow single-family homes, or that there are height or size restrictions that make your project unfeasible. Another common mistake is ignoring easements or rights-of-way that may limit the buildable area or allow access to other properties.
How to Avoid: Prior to any commitment, request a copy of the zoning map and ordinances from the city planning department or local zoning office. Consult with a local architect or developer who knows the specific city or county regulations. They can help you interpret the regulations and ensure that your project is feasible.
- Underestimating the Geology and Topography of the Terrain
The nature of the soil and landform have a direct impact on construction costs and building safety.
The Mistake: Buying land with a steep slope, unstable soil (such as expansive clay), bedrock, or in an area prone to flooding or landslides without considering the additional costs. Flat land may seem ideal, but if it is in a fill zone, high water table, or wetlands, the foundation will be more costly and complex, and may require additional permits.
How to Avoid: Have a geotechnical or soils study done before you buy. This study, performed by a geotechnical engineer, will determine the bearing capacity of the soil, the presence of groundwater and recommend the appropriate type of foundation. If the land has slopes, consult with a civil engineer or architect to estimate the costs of grading, earthwork and retaining walls. Visit the site in different weather conditions, especially after heavy rains, to observe natural drainage.
- Ignoring the Legal and Documentary Status of the Land
Clarity of title is critical in the United States.
The Mistake: Buying land without the seller presenting a clear and clean title, or without verifying that there are no liens, mortgages, judgments, or encumbrances affecting the property. Another mistake is not confirming the exact boundaries by means of an updated topographic survey.
How to Avoid It: Legal advice and title inspection are a must! Hire a real estate attorney or title company. They will take care of:
Perform a title search to verify the chain of title and the existence of any encumbrances.
Make sure the survey is up to date and matches the legal description of the property.
Obtain title insurance, which will protect you from future claims on the property.
Verify that the property taxes are up to date.
- Failure to Verify the Availability of Utilities
Infrastructure services are vital to the livability and value of the property.
The Mistake: Buying land that does not have easy access to potable water, sanitary sewer or septic, electricity, natural gas or telecommunications. The costs of extending these services can be very high and time-consuming.
How to Avoid: Check with local utilities about the availability of connections and the cost of hookups or line extensions. If the land requires a septic tank, make sure the soil is suitable and a septic permit can be obtained from the local health department. Confirm that the land has adequate road access, either public or through an access easement.
By being aware of these common mistakes and taking the necessary precautions, you will be able to make a successful land purchase and lay the groundwork for building your dream duplex in the United States.
