The appraisal format changes November 2, and the submission date is what counts

Two pieces of plumbing, neither of which gets explained anywhere. The Uniform Appraisal Dataset is the standard format an appraisal report is written in, so that Fannie Mae and Freddie Mac can read it by machine. The Uniform Collateral Data Portal is the single site a lender uploads the finished appraisal to before the loan can be delivered. Every conventional appraisal passes through it.

The format is being replaced. The familiar family of appraisal forms gives way to one dynamic report, the Uniform Residential Appraisal Report. Both formats have been accepted through a long transition window. That window closes.

Almost none of it is yours, and it would be dishonest to hand you a task list. On a brokered file the wholesale lender or its appraisal management company orders the appraisal, and the lender uploads it to the portal. Neither keystroke belongs to a borrower or an agent.

What reaches you is second order, and it is real enough to plan around. If a particular lender or its appraisal vendor is slow to convert, files start bouncing in early November and the delay lands on whoever is sitting on a purchase contract.

It does not change whether a property appraises, what an appraiser looks at, or how value is reached. This is the shape of the file the report is written on, not the judgement inside it.

It does not change what anything costs, and nothing here makes a loan cheaper or more expensive.

It does not apply to every loan type in the same way. This is the conventional agency channel, which is where the portal sits.
