@Eric Schenck
Thank you for your service. . .
First, yes, I have been in the situation you are concerned about regarding your current house. . . do you sell or rent upon PCS. . . My wife loved the house we bought in Texas and when it came time to leave, she was a bit torn on what we should do. . . Eventually we settled on renting it, with a PM, and after three months it was rented to another military family that remained in place for 4 years until we moved back into it. . . we knew it was likely that we would have to get it to our level of "liveable', but to our surprise, the tenants took great care in the house and even added a few beneficial features. . . Fast forward a two years and those same tenants now live next door.
Secondly, I would recommend you take research the VA loan timeline again, you said that you determined that once you get out of the military, you would be unable to use a VA loan again. . . I recently went to an extensive VA Benefits seminar and heard several times from the representative that VA loans are available for any Soldier, serving or ETS or retired, as long as the loan does not exceed the cap for that respective area as well as total cap for one person to have. . . The only contingency there is that a Soldier that has ETS'd must have a honorable discharge. Again, this is what they told us, I recommend calling VA directly or visiting their website for the ground truth.
