Seller lives out of town and does not have a key to the property

[Bruce Bell]

I am a wholesaler who is fairly new to the business. I have a potential seller who's property was flooded a few years ago and is in pre-forclosure. He also says he got rid of his key when he filed for bankruptcy. He now lives in a different city as well.

How I should go about gaining access to the property?

Also should I try to get this property under contract before I gain access to the home?
