Looking for any suggestions for portfolio lenders in Maryland who will cash-out refinance a cash-flowing rental property with no existing mortgage.

If the seller was not aware and found out that you are selling the house to someone else, they might be playing a game with you.

Talk to any Portfolio (Asset-based) Lender.

I meet investors who started with TK just to get into the game and then did BRRRR when they had a nest egg of a portfolio. 

The last time the house sold was back in 2010 for ~144k. 3 family house in question has its issues(older home, older heating systems probably)  but I would like to own it as it would: 1. eliminate my driveway/snowplowing issues 2. add to rental portfolio 3 increase monthly income 4.

This is not a VA loan its just a small local bank and they keep these loans within there portfolio. 

Echoing what @Andrew Beauchemin said, you can find out owners of buildings by looking at property tax records on your county's appraisal site. if the owner is a LLC (which is usually the case for larger multifamily), go to your state's secretary of state website and look up the business in the business records search. i'm not familiar with pennsylvania, but that's how every state I've looked at before operates. there is usually an agent of record who oftentimes is the owner, however, for a larger, more sophisticated owner, it could easily be a lawyer or someone else.if that fails, a broker is your best bet. they'll have the relationships with owners and other brokers you need. as others have said, it's hard to go off-market without a track record, but maybe by showing your current portfolio and explaining your desires, you may win someone over :)

I have been looking for reasonable lending options to continue building my rental portfolio past 10 conventional loans.

This will help us build a long term portfolio and still provide enough to make a Little now.
