You can do a simple web search to find brokerage firms that will hang your license for a flat fee verse a % of every sale/purchase but you won't get much assistance from them and I am not sure exactly how "legal" all that is.Other things to consider, 1) there is a fee to have access to and be able to list on the MLS, 2) I think the state requires you to carry or it would be a very good idea to carry Errors and Omissions insurance commonly called E&O insurance 3) if you plan to tour properties, you will need to get those electronic keys that agents have and I am guessing there is an annual fee associated with that.Those are the big ones I can think of off the top of my head.

I find that a very common hurdle that beginners have is assuming what a lender will or wont do. you said "I don't even think I would qualify for a loan of 100K" which may or may not be true, but you don't KNOW. what you really want to do is ask a lender what it takes to get that loan, rather than assume you can't get it and then blindly try to improve what you think they need. does this make sense?

It is common for community owners to not allow home owners to rent out the home.
