NJ investor friendly bank?

Hi.

I have 4 rental properties financed through a niche lender. The rate is high, and I want to do a no cash out refinance to lower the rate. I've had the properties over a year, they are all at or below 70% LTV, I have great credit. I haven't used fnma loans in the past, as my income probably wouldn't suffice. I have them all in my llc name, but I'd be willing to change that if required. If anyone knows of a bank that may be helpful, please let me know.

Thanks.

Harry
