Which lenders allow external-only appraisal?

[Ana Novakovic]

I’m looking to buy a bank owned property on an auction, and going to use a hard money lender. Hard money lenders require an appraisal to be done for as-is value before they lend money, but most properties I look at won’t let anyone go inside before the purchase. Any suggestions on what to do? Are there any hard money lenders that are ok with drive-by external-only appraisals?

Thanks!
