How to deal with Tenant after foreclouse

[Kevin J.]

I am trying to bid on a foreclosure condo. It is tenant occupied unit. My intention is to acquire the property and renovate it somehow and sell it. 

To that end, I want to know what options that I may have to achieve this.  I understand, the foreclosure process will need to respect the existing lease. but, right after confirmation of sheriff sale, what is the process to ensure the current tenant start paying the rental to new owner.

Thanks,

Kevin
