Maybe they've been burned by landlords in the past and are being very careful.You can legally reject them based on personality, facial tattoos, body odor, or other factors, but you better make sure you can prove that it wasn't based on any protected class like race, religion, familial status, etc.

I recommend reviewing your local laws to understand the requirements involved.

I constantly get great reviews often comments of how clean the cabin is.

By reviewing sponsor after sponsor, and deal after deal to uncover what sets apart the good from the bad. 

Also consider all lenders will require to review your insurance when underwriting a loan and it's likely a violation of your existing loan documents to let the properties go uninsured even if they didn't require insurance escrows. 

In our reviews our lake, pool, size of our house and location relative to everything else gets the most mentions.

I mean there is so much to scrutinize here we could spend an entire afternoon reviewing the actual deal let alone the financing.I wish you luck either way man.  

You may have your lawyer review the contract/property management agreement.

The lawyer says he is pretty confident but since he has not read the entire lease, he says he can review it at additional cost if needed.

I also looked up the google reviews and people seem to be very satisfied with their service!
