I guess to provide you with any kind of advice meant for your situation, I would want to know a few things about you and your investment strategy.....
First, where will you go? You mentioned that it is a cash flowing rental, but also stated that you bought with VA. So, are you still living there as well, or did you move out and convert it to a rental? I would hate to hear that you sold your only home and moved into an apartment or something.
Second, what is your end goal? Both for the property, and for your investment strategy? This is something you should have in place, and it guides you through the process.
For the property......You should have a target for each and every property that triggers a time for you to evaluate a sale (notice I didn't say just sell, but rather EVALUATE a sale). This trigger point could be several things like appreciation, increased expenses including HOAs (those HOA fees can creep up before you know it, and make the property less desirable for a new Buyer to take on). Having those target points for each of your properties will allow you to sit down and evaluate whether the property still makes sense as an investment, or whether your funds from the investment would be better served elsewhere.
That answers the property question, but then ask yourself what YOUR long term goal is....?? Are you looking to roll and flip until you have 1 house that is paid for that you can live in? Is the goal to live on the income produced by the investment? Are you looking to grow to a larger property or get into commercial perhaps? Determining this will help you decide. For example, if your end goal is to have properties that support you in retirement (or before), then selling may not be the best move. You have a low principal balance and a killer interest rate that will most likely not be duplicated anytime soon. (Today's rates have VA loans in the 4% range!) So, selling, no matter what the highs or lows, mean nothing if you intend to keep the property as an income stream during retirement. Instead, take the cash flow and bank that into the next property to purchase to build your portfolio, while maintaining a pace you can support financially in the event there is a turn in the market (yes, the rental market corrects too). Don't over extend yourself and put yourself in a position to be over leveraged while you are building. Your house hack strategy is a good one. Since you used your VA, maybe an FHA or conventional with low down payment would be the next move. However, IF your goal was just to make some money in Real Estate to better your position in life, or supplement your job income, then selling might make the most sense to give you a good savings cushion.
Alternatively, before considering a sale, make sure you have evaluated several deals as a replacement to confirm that there is, in fact, a replacement property (or properties) that will make sense for you. Keep in mind the interest rate is shifting, and the market continues (at least for now) to appreciate. So, figure your deals from a conservative standpoint and leave plenty of room for escalating expenses as a result of these things.
Lastly, BPers are great at telling people what to do based on what they themselves would do. But only you can answer the question of what to do based on what your long term goals are. So, sit down with a piece of paper and figure that out first (if you haven't already), and THEN see how a sale fits in, or keeping it fits in. Then BE HAPPY WITH YOUR DECISION! You can only make the best decision for yourself in that moment, and with the info in front of you. It is true that you could sell now, and 2 years from now the property could've doubled. However, you can't live like that. Make the best decision for you, and be confident with the decision, and move forward.
Best of luck to you, and let us know what you decide.
