You'll get 80% of whatever your returns show as your take home. Unless you make no profit, which would beg the question why are you bothering anyway and if this is the straw... then probably for the best.

If you want this to work it will be able to if you get everything lined up.But dsepending on their returns they will get help whereas I will not. At the same time I will be paying rent to someone getting help.
