Hard, because a lot of the low-hanging fruit is gone and you're going to have to get off the beaten path and turn over a lot of rocks.  

Would it be more advantageous for me to just hang on to my property and risk the demand falling in the future?

I would caution you that this is speculative and can come back to bite you if there is a downturn in the market, but if you can hang in there you may be able to ride the ups and downs of the market and choose the time to sell when the market is up.Lots of stuff to consider, but there are several people who have served and obtained properties in their duty station while doing so. 

If not they may be hanging on as long as possible whether they’re safety is at risk or not.

I just plan to host a number of businesses in the main area, and I am currently finding out from an engineer if I could put a full two-bedroom apartment in the attic (space is there, just need the engineering stamps.)So yes, I have the bug, and I'm just going after the low hanging fruits for now, but in the future, I want to flip one house (even it's with a partner where I do the rehab on the side for the experience) then when I get my credit where it needs to be I'll like to get into a small multifamily.

(I have done drywall, skim-coating, electrical, plumbing, hanging doors and windows, and laid LVP flooring previously.)Any suggestions are greatly appreciated!

I bought my first, and then bought my second a few months later after I got the hang of it. 

Tracking lease end dates is low-hanging fruit in our world, so if they don't have a system for that, you definitely want to move on.
