Buying from a Wholesaler

[Melissa K.]

Hello,

I am looking to purchase a fixer upper from a wholesaler, however, most that I speak with say that they don't have inventory or that their houses go in a day or two.  Are houses really selling that quickly or is that just a statement to get me to buy fast?

Also, once I have a house under contract are there any stipulations that allow me to cancel the contract?  For example, if the repairs cost more than what the wholesaler estimated or if the arv they have estimated is wrong? etc

Thank you for your help!
