What Freddie Mac Requires of a Property Data Collector, and of the Lender Who Sends One

On a growing share of loans the full appraisal has been replaced by something closer to what a field services company already does: a visit, a measurement, a set of photographs and a structured report. What makes property data collection different from an inspection is that the qualification bar is set in the Guide rather than by the client, and the lender who sends you remains answerable for what you produce. Both of those facts sit in one section.

The Section That Sets the Bar

Freddie Mac Single-Family Seller/Servicer Guide Section 5603.6 is headed "Property data collector qualifications and Seller oversight" and has been effective since 6 November 2024. It has two subsections: what the collector must be and do, and what the Seller must have in place about them.

Subsection (a) opens with independence. The Seller, or its authorized third party, must ensure the property data collector "is independent and unbiased and has no present or prospective interest or bias with respect to the transaction, the property or the participants to the transaction." Prospective interest is the limb that catches field companies with another line of business on the same asset - it is not only about today's relationship.

Then competence, and it is tested rather than asserted. The collector must complete "training in all aspects of property data collection and the Uniform Property Dataset (UPD)" and pass "an exam that evidences proficiency in property data collection." A general field inspection background does not satisfy that on its own.

What the Visit Has to Produce

The rest of subsection (a) describes the work, and it is more than a photo set. The collector must perform all aspects of a property data collection including, but not limited to:

• Identifying and reporting, with supporting photographs, any property characteristics represented in the UPD
• Identifying design features "that impair the use of the subject property and cannot easily be changed" - the Guide's own example is access to a bedroom only through another bedroom
• Identifying factors adjacent to the subject property "that are atypical for the location" - the examples given are power lines, a commercial site and an industrial site
• Measuring the dwelling unit or units "and any other structures on the subject property to produce building sketches and floorplans" in accordance with the exhibit requirements in Section 5604.2(a)(ii)
• Collecting a comprehensive set of photographs of the subject property as described in the UPD, with photograph requirements in Section 5604.2(h)

Two of those are judgement calls rather than observations. Deciding that a design feature impairs use and cannot easily be changed, and deciding that an adjacent factor is atypical for the location, both require the collector to form a view and support it with photographs. That is a different discipline from recording whether a door is secured, and it is the part training and the exam exist to standardise.

The measuring requirement is the other practical shift. Sketches and floorplans to an exhibit standard are a drafting deliverable, not a note on a form.

The Lender Stays Responsible

Subsection (b) is the one that shapes how panels are actually managed: "The Seller, or its authorized third party, is responsible for the accuracy and reliability of the PDR and of any data provided by the property data collector to the appraiser."

Responsibility that cannot be delegated has to be managed instead, and the Guide specifies how. The Seller must have policies or procedures that:

• Require property data collectors to undergo periodic background checks "that include criminal background checks"
• Require comprehensive training on preparing an accurate and thorough PDR
• Require collectors to comply with the same customer service standards or code of conduct as the Seller's own employees and contractors
• Include a process to continuously evaluate collectors, "including monitoring and documenting performance to identify and remedy any recurring deficiencies and discontinuing the use of chronically underperforming property data collectors"
• Include a process for providing continuing education when appropriate, for example on significant changes to the UPD or the collection process

Note the shape of the fourth one. It is not a right to remove a poor performer; it is an obligation to have a process that monitors, documents, remedies and ultimately discontinues. A lender that keeps using a collector with recurring deficiencies is out of compliance with its own required procedure, which is why panel removals in this line of work tend to be abrupt once a pattern is documented.

And the work is sampled. The section closes: "The Seller must include a targeted review of PDRs as part of its quality control sampling. Appraisals completed using a hybrid process must also be included in the Seller's quality control sampling."

What This Means If You Do the Work

• Training and a pass in a proficiency exam covering the Uniform Property Dataset are entry requirements, not differentiators - budget for them per collector, not per company
• Check the independence limb against your other work on the same asset; "prospective interest" reaches beyond the current engagement
• Measuring to produce sketches and floorplans to the Section 5604.2(a)(ii) exhibit standard is a distinct capability from photo-documented inspection
• Expect criminal background checks to be periodic rather than one-off at onboarding
• Expect to be held to the lender's own code of conduct, because the Guide requires the lender to impose it
• Expect performance to be monitored and documented, and expect removal once deficiencies are recurring - the Seller is required to have that process
• Your reports will be pulled in quality control sampling, so the file has to survive a review it was not warned about
