Desktop vs. Cloud Appraisal Software: Workfiles, Security and USPAP Record Keeping

The desktop vs. cloud appraisal software question used to be about speed and internet connections. In 2026 it's mostly about something else: where your workfiles live, who can get to them, and whether you can still produce a 2022 file for a state board in 2027 after you've changed vendors. With UAD 3.6 pushing many appraisers to reconsider their software this fall, it's worth understanding both models clearly. This post explains how each one handles your records, what USPAP actually requires, and how to stay compliant whichever you choose.

Key takeaways

• USPAP doesn't care which kind of software you use. It cares that you can retain, access and retrieve the workfile.
• Desktop puts your data on your machine: you control it, and you're responsible for backing it up.
• Cloud puts your data on the vendor's servers: you get access anywhere, and you depend on the vendor's terms.
• Either way, keep your own backup and make sure you can export everything at any time.

What USPAP requires, in plain terms

The rule that matters here is the Record Keeping Rule in USPAP, published by The Appraisal Foundation. In general terms:

• A workfile must exist for each appraisal or appraisal review assignment, with the data, information and documentation needed to support your opinions and conclusions.
• Retention: keep it at least five years after preparation, or at least two years after final disposition of a judicial proceeding in which you testified, whichever is later.
• Custody: keep custody of the workfile, or make appropriate arrangements for retention, access and retrieval with the party who has it.
• Access for others: a custodian has to give other appraisers with workfile obligations on that assignment appropriate access, for example for regulatory submissions or peer review.

Note what isn't in there: anything about desktop or cloud, specific products, or file formats. The rule is about outcomes. Can you produce the workfile, intact, for the whole retention period? Your state may add requirements, so check your board's rules too. This is general information, not legal advice.

Watch out: the five years runs from preparation of each assignment. A report you finished in December 2026 needs to be retrievable into at least December 2031, long after your current software contract may have ended.

How desktop appraisal software handles your records

With desktop software, the program and usually the report data live on your computer.

What's good about it

• You control the files. They sit in a folder you can see, copy and back up.
• No connection needed to work on a report, which helps in rural areas.
• Your old files stay on disk even after a subscription ends, though you may need the program to open them.

What to watch

• Backups are your job. A failed drive, a stolen laptop or ransomware can take years of workfiles with it. One external drive in the same office isn't enough.
• Multiple machines, multiple archives. In a firm, each workstation may hold its own reports.
• Encryption. A laptop full of borrower names, addresses and loan details should have full-disk encryption turned on, and a sign-in password.
• Opening old files. If the old program stops running on a new computer, you'll want PDFs of every delivered report.

How cloud appraisal software handles your records

With cloud, or web-based, appraisal software, your reports are stored on the vendor's servers and you work through a browser or an app.

What's good about it

• Work from any computer, and pick up a report on another machine.
• The vendor handles server backups.
• Firms can share reports, assign work and move reports between staff without passing files around.

What to watch

• Access depends on the vendor. Find out what happens to your data if you cancel, if a payment fails, or if the vendor changes plans or shuts down.
• Export. You should be able to export every report, as XML and PDF, at any time. Test it before you depend on it.
• Account security. Use a strong, unique password and two-factor sign-in where offered. Your account is the front door to every workfile.
• Connectivity. You'll need a connection for most work, so think about inspections in places with poor signal.

Side by side

Neither column wins outright. The right question is which risks you can manage better.

The setup that works either way

Whatever software you use, this simple setup keeps you covered:

1. Save the delivered package with every workfile. The PDF the client received, and the XML. Under UAD 3.6 that's the zip with the MISMO 3.6 XML, the URAR PDF and the images.
2. Keep supporting documents in the same place. MLS sheets, assessor records, your notes, the engagement letter, relevant emails.
3. Back up to two places you own. An external drive kept off site, and a cloud storage account in your name, separate from your appraisal software.
4. Export regularly. Monthly or quarterly, export your recent reports from your software into that backup, so you never rely on a single vendor to retrieve them.
5. Protect confidential information. Encrypt drives, use strong passwords and two-factor sign-in, and don't email unprotected workfiles around.
6. Check retrieval once a year. Pick a report from five years ago and make sure you can open the whole workfile.

Tip: name each workfile folder with the file number, effective date and address. When a reviewer asks about "the March 2024 report on Elm Street," you'll find it in seconds.

What this means when you switch software

Changing software is the moment record keeping most often breaks. The old program gets cancelled, a laptop gets wiped, and a year later a lender asks for a file you can't open.

Before any switch:

• Export every finished report as MISMO 2.6 GSE XML and PDF (most desktop programs can, including ACI and TOTAL).
• Copy every workfile folder as it is, to your own backup.
• Keep the old program available until your UAD 2.6 revisions are done. Freddie Mac's UAD and Forms Redesign FAQ says revisions to reports first submitted in UAD 2.6 stay in UAD 2.6, and UAD 2.6 is retired June 28, 2027.

The full process is in our pillar guide, how to switch appraisal software without losing a decade of comps, with program-specific detail in migrating from ClickFORMS and leaving ACI, TOTAL or other desktop software.

Questions to ask any vendor about your data

Copy these into an email before you sign up for anything:

1. Where is my report data stored?
2. Can I export every report as XML and PDF at any time? Is there a fee?
3. What happens to my data if I cancel, and for how long can I still get to it?
4. How are reports shared between users in my firm, and who controls access?
5. What account security options are there, such as two-factor sign-in?

Good answers make the choice easier. Vague ones tell you something too. The buyer's guide to UAD 3.6 appraisal software has these and the other criteria in one checklist, and appraisal software pricing in 2026 covers whether export or access costs extra.

Where Carat fits

Carat is web-based. Firms work as one organization with roles, assignment, and transfer of reports between staff and trainees. Our principle is simple: your data stays yours. You can export any time, and the plan is $99 a month per appraiser, month to month, so your records are never the reason you can't leave. We'd still tell you to keep your own backup of every delivered package and workfile. USPAP puts that responsibility on the appraiser, and that's the right place for it.
