Making offers on Bank Owned Properties

Hi, I have made several offers that are great offers. All cash, over asking price and quick close with no contingencies. Each one has been ignored. It is always the same realtor that is doing the listings.

I already have a good relationship with my realtor ( he is also my property manager for my rentals)

I almost wonder if I should be making these offers through the bank listed realtor instead of my guy.

Last house was listed for 43,900. I offered 48K, all cash and no option and quick close. I was rejected twice for the same property.

The other house was 64k and I offered 68K-all cash, no option and quick close.

Same guy for these houses. He also has this irritating pitch, on all of his MLS listings. Multiple Offers received. Especially on day 1.

I am most irritated. Thanks for your advice.
