Using deposits as leverage for loans

[Tony Schober]

Lets say you want to buy homes for cash to close quickly and cash out refinance to continue to buy homes over and over again. Lets also say you have a hypothetical 1 million in the bank.

The bank you are working with has done a refi a half dozen times and decides not to approve anymore loans. Would any of you use that 1 million in deposits as leverage, or do you think this is unethical?

By leverage I mean that if they don't want to lend, you will move your deposits to another bank. I would think they would be more receptive if you had a large deposit with their bank, but I also think that if you "threatened" to withdrawal your funds, that it would ruin any future relationships. What are your thoughts? Do you think banks would be more willing to lend to you if you keep a large deposit with them?
