Contractor asking for money for an Estimate?

[Charlene Gay]

I’m in the process of purchasing a multifamily using a 203K loan. I’m reaching out to several contractors trying to get some estimates in place to bring to my lender. I had one contractor reach out to me and say the cost to go out there for a quote is $750 because everybody else is just guessing and they are actually going out there with the structural engineer and will be able to provide me a detailed quote. Is this normal?
