Second, homes are selling in Front Royal! Your first step is to contact a reputable experienced agent to determine the current fair market value of your home, what is the estimated time it will take to sell and what can you expect to net financially from the sale. Only then will you have the information to make an informed decision.
If the finances work out for you then make sure you check the rental market is in your area to see how many rentals you may be competing against, how long it will take to find a good renter and what your liabilities will be as a landlord. Since you are staying in the area you could probably manage the property yourself but not everyone wants to be a landlord.
Those are my recommendations to get you started. Good luck !
