Portland, Maine - Good Rental Properties?

[Matt S.]

I'm new(wish) to Bigger Pockets and researching cities to expand my real estate investments. I'm targeting small multifamily properties. 

I recently stumbled upon Portland, Maine. Having grown up in NE, I often hear friends/family rave about how great Portland is (great food scene, artsy, craft breweries, young people moving there)...all the signs of gentrification. I found very few posts on this city, so I'm wondering if anyone is investing there that could provide some input. Doing some preliminary research, it appears you can get close to 1% rents on MFHs, taxes are higher than the midwest (but not crazy) and I assume there's strong potential for appreciation.

Anyone out there having success in Portland?
