@James S. it's been a fun time but not exactly "home".
As far as towns, I'm primarily looking at Dover/Dover Point, there are a few duplexes in our price range, unfortunately around Broadway St, they look in "ok" condition from what I can tell from the internet, our agent will be doing a preview for us and we have a friend on the ground who can do a walk through to see if we should nix it from the list or pursue.
While the Broadway St isn't great, I think if we start with one there and add a few to our portfolio in the long run, gentrification will win out. As people are priced out of Portsmouth they're moving to Dover, so hoping that rents will increase in the long term.
Somersworth and Rochester are a tad... troublesome, as far as residents.
Long term plans as well is to get the units and be able to manage everything in terms of services provided to it as well (bundled cable, internet and solar). As a technical professional, I see value in being able to modernize and provide solutions to not only improve property value but income potential. I've got a solar provider that is self install that per panel it's is around $350/installed, plus costs of electrician and battery units. Probably all a bit ambitious for starting out but with NH energy prices and the instability of the power infrastructure during storms, I figure adding something like that in will add value to a renter's prospective as well.
