Quote from @Sherry McQuage: Make sure to check the zoning to make sure mobile homes are permitted there; check for any hazardous waste designation for the area; will you need to have the parcels surveyed out in order to sell the size you intend? 

And what if the one person you didn't check has a criminal background, has collections, and more?

Did you check for houses on the auction list,  or you can check with banks and look for REOs and convert that into a single family home and house hack or turn it into a Airbnb.

Will check with my local bank to see if they have options.

You would have to check the loan terms.
