Of coarse there will be surprises & unexpected things that you can't plan for.

There are exceptions, deployment, unexpected and non-voluntary PCS, etc....

AGain - just my view - I may be 125% wrong - and I'd be delighted for someone to show my why that is so.  

You have to really analyze where the project could go bad and have contingencies in place in case you run up against them - i.e. the house doesn't sell, you have unexpected costs during projects, what the SOW of the project will entail, what your marketing costs are (his wife as an agent will help minimize these costs), what if something unforeseen happens and you cant finish project, whos name the house will be under, and that might determine who will be able to pull permits if needed, etc.Anyway, you should spend A LOT of time going over "what ifs" and sit down with your attorney and pound out these details.

Lots of factors, any family or friends to help in emergencies,, how flexible is your current job if you had someone you needed to meet can you leave work for hour or 3.. with short notice...some issues can wait others can't, usually things go well but be prepared for the unexpected.

I talked to the PWB yesterday about an unexpected mondo bill.  

I unexpectedly began my real estate investing/rental property career in 2007 after a job transfer forced me to quickly become a landlord. 

The area around the Navy there should be a continual demand area with potential build up of military and should help you sell.There will always be unexpected expenses. 

After the buyout was signed one of them says he received an unexpected offer and the family will be moved to NYC for what I presume is an even higher paid job.
