Land deals — especially government land deals — can offer extraordinary value. They also come with real risks that are different from buying a house. Title defects, zoning surprises, environmental contamination, unknown occupants, and liens can turn a great deal into a costly problem. This module walks through every major risk category and what to do about each one.
Title risk is the risk that the property doesn't actually belong to who you think it does — or that someone else has a legal claim against it.
Historical deed records may have gaps, forgeries, errors in names, or unrecorded transfers. These can cloud ownership.
Unpaid mortgages, IRS tax liens, mechanic's liens from contractors, HOA assessment liens — any of these can survive a sale and become your problem.
In some states, unknown heirs of a deceased owner can come forward years later claiming inheritance rights to the property.
In some states, someone who openly occupies land for a statutory period (often 5-21 years) can claim legal ownership. This is especially relevant for rural land.
Seller impersonation fraud, forged deeds, and straw buyer schemes do happen. Using a title company reduces this risk.
Prior industrial use, dry cleaners, gas stations, and farms can leave heavy metals, solvents, or petroleum products in the soil. A Phase I Environmental Site Assessment identifies these risks.
FEMA flood maps determine flood insurance requirements. Properties in Special Flood Hazard Areas (SFHAs) require mandatory flood insurance, which can cost thousands per year.
The Army Corps of Engineers can restrict or prohibit development in wetlands. A wetlands delineation may be required before building permits are issued.
Old heating oil tanks or buried chemical tanks can cost $20,000-$50,000 to remediate. Common on old gas stations, industrial sites, and farms.
Any structure built before 1978 may contain asbestos or lead-based paint. Demolition or renovation costs increase significantly.
Some properties sold cheaply have been used as dump sites over the years. Look for uneven ground, odd fills, or suspicious materials during physical inspection.
Just because land is "residential" doesn't mean you can build anything. Setback requirements, lot coverage limits, and height restrictions all apply.
A parcel next to yours can be rezoned in the future — a quiet residential street can become a commercial corridor.
A property with a pre-existing use that doesn't meet current zoning (a "grandfathered" use) loses that status if the use is abandoned for a period — often 12-24 months.
Private restrictions can be more limiting than zoning. Some subdivisions prohibit manufactured homes, limit building sizes, or require minimum construction standards.
Some areas have tax increment financing districts (TIFs), community development districts (CDDs), or special assessment districts that add significant annual costs.
Very common. A neighbor's fence may be 5 feet onto your property. If you don't address it, you risk losing that strip through adverse possession.
Equally common — you may have built (or a prior owner built) something that technically sits on the neighbor's land.
Power lines, gas lines, water mains, and sewer lines often run through properties. You can't build on these areas and may have to grant utility companies access.
Some land has permanent conservation easements held by land trusts or government agencies that prohibit or severely restrict development.
Water flowing across your land may give neighbors rights. In some states, easements for natural drainage are automatic — if you alter the land, you can cause flooding downstream.
Government-assessed values are often below market, but after purchase, the assessed value may be updated to reflect the purchase price — increasing your annual tax bill.
Some counties tack on back taxes, demolition costs, weed mowing, or infrastructure charges that aren't captured in the initial price.
Unlike home mortgages, land loans typically have higher interest rates (8-12%), shorter terms (5-15 years), and require more money down (20-50%).
While you own the land, you're paying property taxes, insurance, and possibly HOA fees — with no income from the property.
If you hold raw land for 10 years before building, you may have paid $5,000-$15,000 in taxes and insurance — on top of the purchase price.
Governments can take private land for public use (highways, utilities, public buildings) with compensation. This is rare for small residential parcels but does happen.
If someone is living on or occupying the property when you buy it, evicting them can take 3-6 months through the court system in most states.
In very rare cases, property connected to criminal activity can be forfeited to the government even after a legitimate sale — though proper due diligence makes this essentially unheard of.
Even if zoning allows your intended use, specific site conditions (wetlands, access, slope) can cause building permits to be denied after purchase.
