I don't own in Middletown. That said though strategy is important. If your doing an FHA and plan to stay in one side you have to figure out what that would benefit you. I don't know your living situation but if your paying x,xxx for rent or a mortgage and instead by living in one side and renting out the other you will be paying y,yyy instead and y is less then x that's great, especially if you can rent out your primary residence and make income there too.
I think the best thing to do is live in one side and rent the other when your starting out, I wish I did. You can always leave and repeat the process and rent out your old living area.
My 2 cents is prices are crazy inflated right now, but believe it or not I think it will continue because of continued demand pressure for the area from people fleeing higher cost of living areas and moving there, with access to 87/17. At the end of the day if you run your numbers and analyze like 10 properties a day, and every single day scour the internet for anything new, you will eventually find something that works and know it almost immediately. Good luck!
