Minnesota bank recommendation for portfolio loans

[Todd M.]

I have 4 traditional mortgages and looking buy another multi-family or commercial investment property.  I believe I need to find a bank that provides portfolio loans, right?  Or smaller banks which hold the loan.

Any recommendations for banks in Minnesota... in or near Minneapolis?

I have over 5 years REI experience. It sounds good to work with a local banker and consider the investment itself rather than a deep dive of my debt to income. I understand I can hope for up to 70% LTV.

Thanks in advance,

Todd
