|The homes which signing agents are asked to inspect are typically mobile homes, and the loans for which the signing agent has been asked to visually inspect the property probably are loans on personal property, not real property.|
Again, the lenders are not asking for a termite certificate, or an engineering validation of construction soundness. They want to know there are not holes where the kitchen sink and the bathroom toilet should be, that you can't see the sky through the ceiling, and that the floor did not cave in under you before you left.
You are the lender's eyes on the site. If they thought an engineer's eyes were necessary, they would hire an engineer. They just want to know that all the cows they bought are indeed in the barn. Or the feedlot. Or the meat locker.
