How soon can I refinance?

[Brock Y.]

I am in the process of buying a property in Chicagoland. Let's just say it's been less than ideal process. I am usually not one to get annoyed but it seems as if the lender is doing anything they can to not give me the loan. I have provided everything they want so they find more for me to prove. I have provided over 20 bank statements, letters of explanations, etc. To this point and am currently needing 4 more.  I would go more in depth to the absurd requests that make no sense but it's not for here nor there.

My question is, I am so far in the process I am going to go through with this lender but how quickly can I refinance with another? I hate the idea of them getting any money through interest of the poor service they have provided. I have purchased other properties and have never had a problem.
