I would say that you should stay in your current place, and find something else to rent out, for the following reasons:
- Moving is expensive. Not just the actual cost of the move itself, but what about the expenses with setting up a new house? Will you need to purchase new furniture because your old stuff doesn't fit? I had to move from one condo to the next in my complex, and I was out about $1000 in total. I saved a ton of money because my friends helped me move and my landlord owned both places so there wasn't renting two places at one, but there are always unexpected expenses. It was different when I was in college and all of my worldly possessions fit into my Honda.
- Moving also has a non-monetary cost. It's time consuming and stressful. That's time you could spend driving for dollars, researching better deals, or just enjoying yourself.
- The profit margin on your place seems slim. Even if you self-manage, have no maintenance or cap-ex for the first few years because your house is in perfect condition, a single month of vacancy will wipe out your profits for the previous six months. Add in turn-over costs, and you could find yourself in the red for the entire year. And self managing doesn't really save you money because your just trading time instead. Sounds like a job to me.
- You can do better, with less risk, elsewhere. Baltimore City is one option, but so is Baltimore County, Frederick, Hagerstown, Aberdeen, etc.. There are other places within an hour drive that the hit 1-2% screening rule.
- Your bank might throw a fit because you likely have a residential, FHA mortgage on an investment property and you've only lived there for a few months after refinancing. This may trigger a default. I might be wrong, but this is definitely something you might want to ask a mortgage broker about.
Personally, I would stay, unless there is a compelling reason to move, such as the desire to shorten your commute, you want to be in a better school district because of your school-aged kids, or you hate the house you're in. I think, as it stands now, you're going to end up losing money by renting out your current place and by buying a new one.
If you did want to move, I would strongly think about buying a 4 unit multifamily property and living in one of the units. You'd be downsizing in space, but your new mortgage would be almost entirely covered by rental payments from the other units.
