Best part is... it's basically all free!

Only problem is that may entice them to invite friends and family for laundry parties.

We see these often in foreclosure where we ask the court in a declaratory judgment action to hold that the leases aren't valid and to strike the agreement between the parties because it's not good faith and fair dealing.There's likely precedent to that effect in your state, but it's so much harder to cure a bad lease than to not buy the property with a bad lease on it. 

However, if there is a fair solution to both parties, I want to find it.

Best part is that person will get BAH (extra military pay) for that rent for the place while they are at training. 

In this case I would have the tenant remaining sign a new lease with the remaining term of the original (unless they wanted a different length)And then I would write a separate half page document cancelling the previous lease and have everyone one sign it.This scenario is why I like all parties to qualify financially if there's unrelated people on a lease.

50% rule for the most part is designed to be taxes, insurance, maintenance, management, capex, vacancy, etc. 

I would always use third parties. 

.#3 Double Close Versus assignments.Simply put, double close to protect the wholesalers & all related parties much better than assignments.

The house was put up for action Jan 21 and was sold to a third party site where I can bid.
