I think some will lie about their inspection date to comply with the 24 hour turn time after inspection. I never would do that. Sounds like a crappy lender I would tell others never to use. Lenders might not think its not a big deal, but I tell people about lenders that are digging for the lowest quality appraiser who will slam it out in an hour. I think its a good idea to inform people. People don't buy homes much and get shell shocked later in the process with a lender.
Never worked for a company that demanded 24 hr turntime after inspection, but if I did I would make sure I could deliver it 24 hours after inspection. I would have to do a lot of pre-research to make sure I can deliver on it. I would also have to delay the inspection even if I were next door the same day I get the order. So I might schedule it out a week or 2 instead, and I'd have to charge more because I'd have to do more pre-research not knowing what the property will be like exactly. Oh yes and a fee for my pre-research if if they cancel.
Another lender might get it 24 hours or 48 hours after inspection and get the report sooner, but I would respect the lender's SOW if they demanded it 24 hours after inspection if they paid me enough to delay the inspection to a time I'm less busy and do the extra pre research.
