Most portfolio lenders want to see a value of at least $50,000 per property and have a minimum loan amount of $500,000. It appears based on your assumption of combined value you meet this criteria. There is a list of national portfolio lenders available on this site that may be able to assist you.
Cold call them and ask. Most likely it's going to be a local bank vs your bigger banks. I would recommend Alliance Bank (based out of Gastonia, NC). Not sure they can do it but worth a phone call.
