It really depends on how bad the weather is… If it is raining or snowing, then most likely, yes. Rain mostly slows down the exterior part of the inspection, which is only one piece of what a home appraiser looks for.
If there is a hurricane, tornado, or another dangerous weather system, then the appraiser will most likely reschedule. A rescheduled visit runs the same way as the original would have, and the time the appraiser spends at the property stays about the same. Here is what to expect from a home appraisal from start to finish.
