A couple super rookie Questions

[John Magana]

First, if I acquire a 4/2 and want to rent midterm to 2 different people, I am charging each person rental of a room and the use of the premises. I guess I just need to hear someone say "yes". So I will sign a rental contract with each tenant and they will each have their own rent to pay, even if they travel together. What if they are a traveling husband wife couple? Same thing yes?

Second, when looking at zillow listing and I see 3% buyers agency fee is this a fee that I the buyer am paying at closing or is this the sellers side? If it is the buyers side is this negotiable or should I even worry about this as a good relationship with a realtor is worth so much more?

Thanks everyone.
