Are lot dimensions required for fha?

All home loans have a plat survey done by the title company, and the appraiser also reviews the lot size. Normally lot size isn't much of an issue unless you are doing a large acreage loan.

Lot size is not needed by FHA but your appraisal will give the amount of square feet that lot is. They will take a look at see what % of the overall value the land is in comparison is to the house.
