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.

If you maintain ordered and timely communication between all involved parties, have excellent interpersonal skills, are business-minded and un-stubborn with eternal patience for customer interaction and able to remain calm and professional in any discussion environment, then you're a cut above most of the field.As far as growing into top-tier, decide what demographic that means in your community and break into it. 98% of my work is client referral and over the years I've moved past the "hungry" phase of doing anything for anyone, having my hourly be sliding scale, etc. and into being busy with work that I actually like doing and what I want to be doing.

The tricky part is finding the ugly duckling property that needs LOTS of cosmetic work.

To get it deeded you would have to go to court or have both parties agree to put it on both deeds as an easement.Only real problem is that if you need to upgrade or change something, at that time, you may be required to stay on your own lot.
