What if a property is bought at auction and there is a tenant with a lease?

[Jason Krick]

Hey everyone,

I have been following a house closely that is scheduled to go to auction in January. Currently the owner is trying to do a lease option. I scheduled a visit at the property. I was upfront with him and told him that I didn't want to necessarily to a lease option, but inquired about doing a sandwich deal.  He clearly wasn't interested and cooled considerably.

Anyway, I like to plan for everything, and if it goes to auction, it would be a good deal of it can be had for the judgement amount, as a flip.  I would do a title search, etc, but I wonder what would happen if he signed a tenant, and still neglected to keep it from the sheriff's sale.  Would the winning bidder be obligated to honor the lease?  Would there be a way to find out if a lease exists prior to the sale?  Thanks in advance!
