Unless you have reason to think that the area you're in will continue to rapidly appreciate (I know Seattle is on fire now, but I'm not sure this can last that much longer), I would lean toward selling.

It is growing quite rapidly.

Hi, I am looking at investment opportunities in Cedar Rapids, Iowa and looking for an agent to work with.

 Hey guys, I am here in Grand Rapids as well!

Looking to find a grand rapids michigan based lawer that can help answer a quiet title question and then handle that process if appropriate.  

Hello Everyone, I'm a part time investor and run EPIC Property Management in Cedar Rapids, IA.

Even better...once you acquire several properties, you can take the extra cashflow from all of them and rapidly pay down one mortgage at a time.  

So with just $100K, you could put a down payment on three or four properties and keep a good chunk for reserves, let tenants pay down your mortgages and either keep the cash flow as supplemental income or devote it all to rapid pay down.

Also, knock down potential  - old tired rentals in the rapidly changing neighborhoods around down town areas.
