Survey Plat
A detailed map or drawing prepared by a licensed surveyor that shows property boundaries, dimensions, improvements, easements, and encroachments. Survey plats are essential for establishing exactly what land is included in a property transaction.
Understanding Survey Plat
A survey plat (or survey plat map) is a scaled drawing that depicts the precise boundaries and features of a parcel of real property. Prepared by a licensed land surveyor, it shows property lines with courses and distances, the location of buildings and other improvements, easements, rights-of-way, setback lines, flood zones, and any encroachments.
Surveys serve multiple purposes in real estate transactions: they confirm the property's size and shape match the legal description, reveal encroachments (structures crossing property lines), identify easements that may affect use, and provide the basis for title insurance coverage of boundary matters.
For tax delinquent property investors, surveys are important but often expensive relative to the property value. Investors must balance the cost of a new survey against the risk of boundary issues. For urban lots with clear platted boundaries, a survey may be less critical. For rural or irregularly shaped parcels, a survey is essential.
Existing surveys may be available from the county records, previous owners, or the title company. However, surveys become outdated as improvements are added or removed, and lenders typically require surveys less than a certain age (often 5-10 years).
When acquiring properties at tax sales, surveys are rarely available beforehand. Investors should budget for survey costs in their acquisition analysis and order surveys promptly after purchase if they plan to resell with title insurance.
Real-World Example
An investor purchases a tax-delinquent lot and orders a survey before resale. The surveyor discovers that the neighbor's fence extends 8 feet onto the purchased property, and a utility easement runs through the center of the lot, effectively preventing construction of a large building. These findings significantly affect the property's value and the investor's exit strategy.
Texas-Specific Information
Texas surveys must be prepared by a Registered Professional Land Surveyor (RPLS) licensed by the Texas Board of Professional Land Surveying. Texas title companies use the T-47 affidavit as an alternative to a new survey when an existing survey is available—the seller certifies that no changes have been made since the prior survey. Survey costs in Texas typically range from $400 to $2,000+ depending on property size and complexity. Texas follows the metes and bounds system for rural land descriptions and platted lot-and-block for subdivisions.
Related Terms
Easement
A legal right to use another person's land for a specific purpose. Common easements include utility access, shared driveways, and drainage rights. Easements 'run with the land' and transfer to new owners.
Deed Restriction
A limitation on property use recorded in the deed or a separate declaration. Deed restrictions control what owners can and cannot do with their property, such as architectural standards, permitted uses, and prohibited activities.
Title Commitment
A preliminary report issued by a title company that describes the current state of title to a property and lists the conditions under which the title company will issue a title insurance policy. It identifies any liens, encumbrances, or defects that must be resolved before closing.
Due Diligence
The investigation and research conducted before acquiring property to verify condition, ownership, value, and any issues that might affect the purchase. Thorough due diligence protects buyers from costly surprises after closing.
Encumbrance
Any claim, lien, or liability attached to real property that may affect its value or transferability. Encumbrances include mortgages, easements, liens, deed restrictions, and any other interest held by someone other than the owner.
