Possible move to portland

I’m a 45 yr old mail carrier in upstate Ny and it’s a long time coming that I get out of here again. Lived in portland Oregon in my 30s but I’m from downstate Ny. Been upstate like 8 yrs. I’m much more in tune if I’m going to be staying in the northeast for somewhere slower quieter but also has concerts and things to do. Fell in love w portland Maine on a vacation once. Have failed to get back. Thinking of just putting in a transfer there and making it an endgame location for me. My question is this though. Is portland affordable w say 1300 rent tops? I pay 1100 where I’m at but I can afford more. Maybe even 1400. Any recommendations on the neighborhoods that this would be possible for a one bedroom. Somewhere not too overwhelmingly yuppiesh or hip but still a Good neighborhood vibe. Somewhat close but doesn’t have to be super close to the center of the city assuming that’s the station I initially have to go into. I guess the outer areas I could research once I’ve been there but looking for a pretty short commute. Any info appreciated. Thanks
