.- I go to military training on the 7th.I have a good lock on my interest rate and afraid of doing the mortgage application over again due to a slight decrease in my current job pay but will be going up again in a few months and I'll also be house hacking once I own and solely live in the house.

So if you are looking to house hack in N Dallas, I would focus on a value add SFR you can get under market, perhaps. 

Address the leak immediately, once the house is water tight get everything dry and then you can approach the cosmetic repairs over time. 

Depending on location they can cost a lot to replace but when you factor in what you save from paying sewer bills it’s cheaper in long run.It would not stop me from buying a house

And that educational out, you know, where you get a degree that offers you upward job mobility, where you move into a big house, and you drive an expensive, late-model car? 

Thereis  too much info for here but given your stated information, I'd do the chapt 7, save what I can, and move on.If you mentioned you owned a house, the recommendation would be different.

I am closing on a house and family member of the owner is living there, who has no lease, or should be in the house once I close.

EDIT - The house itself is a bit boring IMHO.

In-house engineers: The best firms have specialized engineers on staff, not just hired contractors.

From my limited political understanding, the House included 100% bonus in a bill from February but it is stuck in the Senate.
