He was a sergeant in the United States Marine Corp before being honorably discharged.

That will give any papers filed against that owner/property (like a mortgage) Anything that has been discharged (like a mortgage) should also be recorded.

Since I filed for a chapter 7 bankruptcy in May of 2014 and it was discharged in August of 2014.

It occurred to me that a couple of years ago I created a bathroom in a lake house we had and I had to put in a rear discharge toilet (sounds redundant) to avoid cutting into the slab by drilling a hole through a cinder block wall. 

I am a recent honorably discharged vet (Navy) and I work a 6pm-6am 12 hour shift w-2 job. 

In general, How is DTI measured in relation to discharged debts still being paid but not reaffirmed?

The mortgage debt can be discharged as a function of the plan which means the debtor no longer personally owes on the debt.  

For VA home loan purposes, a veteran is a person who has served or is currently serving on active duty in the United States Military or Coast Guard and who was discharged or released from active duty under conditions other than dishonorable.

Lodger has verbally agreed to surrender premises (mailed back keys from jail) and but stated since has no living family members available, requested his security deposit back and month to month storage of personal property (passport, social security card, US Army Veteran Honorable Discharge paper, about 5 suitcases of clothing and a couple milkcrate size boxes of misc personal belongings, that's it).

Obtaining the quit claim deed as well could save them costs as w/the bk discharge they can't attempt to collect/contact if chp7 without a reaffirmation agreement.
