Arlington REI | Moment to buy?

[Jake Van Havenaar]

I am currently trying to enter the real estate market while I am gathering enough equity for it, in doing so, I found out that a city called Arlington(next to Washington DC) has some offers that are (to me) a potential investment.

My question is only, how and where can I verify that Arlington is a good city to invest in? In addition to that, how can I determine which city/state/area is good for real estate investing?

In advance, thanks for reading and your time
