UOG: Demise

I'm new to the game and I could not put a vendor in my house. Could someone please clarify my question?

your house has to be set to public to place vendors, that might be your problem

I've already passed it to the public, I used the deed and he asks me to choose where I want to put the vendor in my house, I choose the place and he throws the deed on the floor. After that what do I do?

you bought the wrong deed. one is rental one is for house owner. you need the vendor owner contract not rental

Thanks a lot Loler.
