My 2 cents is that you should spend that 25K and get another place if you have money to invest . There are great prices right now...you could find a plex or you may want to just find a single family home and then You can continue to rent out your current place entirely (are you close to a university to get some roommates in there? -as one idea) and the rent for that will likely make it feasible for you to find some place where you would have no renters under foot but still have the benefits of the investment as well as your own privacy.
If you need assistance regarding your real estate pursuit I'm happy to discuss the possibilities with you.
