Sheriff's sale - how to buy for an investor

Hello BP,

I have an opportunity to buy a home from a sheriff's sale.  In oreder to close on the house you must have 100% of the cash the day of the auction.  Sale price will likely exceed $270,000.  The property is easily worth $340,000 as is.  I have an investor willing to front the money.  The plan is to have the investor buy the home and then I will get traditional financing through a bank.  I've already been pre-approved.  The question is, can I buy the house for the investor in his name?  I'm thinking he could wire funds to Walmart in the form of a cashiers check.  I would then take that check to the sheriff's office and purchase the property in his name.  Will that work?  Is there a step in this process I am missing? It seems so simple in my head.  

Thanks,

Troy
