One of the easiest to make the largest amounts of money as investors. 

If only half the rent is paid, they are still 100% responsible for being late and subject to fees or eviction.Personally, I wouldn't want a married couple renting a room because that will result in an increase of utility use, wear-and-tear, etc.

Project scope creep happened a little and i made some rookie mistakes (allowing my carpenter to do the plumbing and him realizing half way through we need a real plumber, not getting permits in the very beginning, under estimating budget).  

My girlfriend has a 4/3 on a lot and a half on a treeless corner, in the middle of Seminole Heights, Rivercrest Park.

First, that property is a half duplex with only 1071sqft and a carport. 

Hi Barbara, I'm going to assume you are not always feeling like the most outgoing person in the room/but have a lot to contribute.Given that, you might want to "adjust" your "goal" from meeting "People" to meeting WITH "A Single Person".Focus on meeting one person and asking your questions and make a "Business Friend" of that person.Then once that's done, repeat the process.Some people do this better in person than on the phone, but once you meet, texting might be polite, if the other person agrees.What's the easiest way to meet someone?

I am now getting my first home and iwant to airbnb the bottom half of the home and fix it up nice to attract high quality travelers.

I never heard of it being legal to sell half of a duplex.

I would imagine each unit would be better, due to less people to deal with, and avoid the place looking like a half way house.

FB is probably your cheapest and easiest bet at this point.
