I haven't dealt with it in a landlord/tenant situation, but from a couple of people I have known who accepted credit cards for their retail businesses, the credit card associations (Visa/Mastercard/Amex) "don't like it" if the business tries to charge the credit card fee to the customer, and can potentially stop accepting charges from that business if they do it.But, the card associations seem to be perfectly OK with the idea of a business advertising or giving a "cash discount".

I can create custom off market property searches and do the leg work like a wholesaler to bring you deals that meet your needs.

With some customs as they come along. 

They can do it at a bunch of other locations.What a customer will accept for a dining experience depends on what they are spending and expectation of quality of food and service.
