Survey

Survey is a formal measurement and mapping of a property's boundaries, dimensions, and physical features performed by a licensed land surveyor. The resulting survey plat or map shows the property's exact location, boundary lines, structures, fences, driveways, easements, and any encroachments — instances where a structure or improvement crosses a property line. Surveys confirm whether the property's physical reality matches its legal description on file with the county, and they play a role at several points in the lifecycle of a mortgage note investment.

Types of Surveys

Not all surveys are created equal. The type ordered depends on the purpose and level of detail required:

For most note-investing scenarios, a boundary or mortgage location survey provides sufficient detail. ALTA surveys are typically reserved for commercial properties or high-value transactions where the title company requires detailed encumbrance mapping.

When Note Investors Need a Survey

Surveys are rarely ordered during the initial acquisition of a note — they are a property-level tool rather than a loan-level tool. However, surveys become relevant in specific situations:

• REO disposition: When a note investor takes a property through foreclosure or deed-in-lieu and prepares to sell it as REO, a buyer's lender or title company may require a current survey before closing. In some states, surveys are customary for all residential sales; in others, they are only required when the title company identifies potential boundary issues.
• Boundary disputes: If due diligence reveals a boundary dispute, encroachment, or discrepancy between the legal description and the property's actual footprint, a survey resolves the question definitively.
• Collateral file review: An existing survey in the collateral file provides useful context about the property — setback compliance, easement locations, and whether structures are within legal boundaries. However, lenders and title companies typically require surveys to be recent (usually within the past few years) to be relied upon.
• Vacant land: Notes secured by unimproved or rural land often require a survey because there may be no visible landmarks to confirm boundaries, and legal descriptions based on metes and bounds can be difficult to verify without professional measurement.

Cost and Timing

Survey costs vary significantly by property type, lot size, terrain, and location:

• Residential lot survey: $300-$800 in most markets
• ALTA/NSPS survey: $1,500-$4,000+ depending on property complexity
• Rural or large-acreage survey: $1,000-$5,000+ depending on size and accessibility

Turnaround time is typically one to three weeks, though it can stretch longer in areas with a shortage of licensed surveyors or during busy spring and summer seasons. When budgeting for an REO sale, include the survey cost in your disposition expense estimate. If the collateral file contains an older survey and the property has not been physically altered, some title companies will accept an existing survey with an affidavit from the seller confirming no changes — this can save both time and money during the sale process.
