What an ALTA survey is and why lenders require it in commercial real estate loans. Key for title, encroachments, easements and underwriting.
An ALTA survey is a detailed, standardized land survey that follows the American Land Title Association and NSPS specifications used in commercial real estate lending to verify property boundaries, improvements, easements, access, and encroachments. Lenders rely on ALTA surveys to confirm the legal description on title documents and to identify any physical or recorded conditions that could affect collateral value or marketability. The survey often becomes an exhibit to the title insurance commitment, and exceptions or required endorsements are negotiated based on its findings.
In CRE transactions, originators order an ALTA survey early in due diligence so the lender, title company, and borrower can identify issues that influence underwriting, insurance, and closing conditions. The survey is reviewed alongside the title commitment and environmental reports to detect encroachments, boundary discrepancies, or unrecorded easements that could require resolution or endorsements. If the ALTA reveals exceptions, the parties may obtain corrective documents, boundary agreements, or title endorsements before funding; lenders may also require an updated survey later in the loan term for extensions or construction draws.
ALTA surveys reduce title and collateral risk by documenting the physical layout and recorded interests on a property, enabling lenders to identify hazards that could impair foreclosure remedies or property value. Accurate surveys can prevent costly surprises such as encroachments, easements limiting use, or discrepancies between improvements and the legal description, all of which can affect underwriting metrics and title insurance coverage. For borrowers and brokers, delivering a compliant ALTA survey clears a frequent closing hurdle and helps avoid delays, additional costs, or loan exceptions that could alter loan terms.
