I picked it up for $12,000 and sold it about six months later for a nice profit.   

@Adam Karr You can try the killz approach, but if it's cat pee, it's probably not that simple.Other avenues are to run a high-power ozone generator and if unsuccessful, replacing the sub floor.

I see 12% mentioned often, but I’m curious if I should just give them a portion or even all of the profit?  

This is a very reputable local non-profit that will distribute funds appropriately to different organizations. 

You can make mistakes and still turn a great profit.

They are an invaluable tool, they know the areas better than I do, can keep me up to date on what I can get for rent in certain areas and keep me in the areas that will be more profitable.  

Do you not think you have some responsibility to a community in that regard or is it simply about maximizing your profit?

If they are an investor than they share in the profits/revenue of the company with you. 

I already kindof know what I want to do to generate leads and find possible deals im just in a bit of an odd location situation.I am currently active duty Air Force stationed in Del Rio Texas, as I have been reading and absorbing information I have been planning on starting my REI career/hobby when I get back to my hometown of Melbourne Florida.

We have around $150k equity in our home and are considering selling and using the cash to move into a property that will give us an opportunity to generate some revenue through house hacking or finding something with a guest house or apartment we could rent out.
