@Ann Bellamy Laconia is definitely on my shortlist for rentals. These are the areas I'm looking at trying to determine their value in chasing - in no particular order:
1. Plymouth/Ashland/Campton/Rumney
2. Meredith/Laconia
3. Bristol
4. Tilton/Franklin (I've heard bad things)
5. Concord (and surrounding towns (Loudon, Pembroke, Bow, etc)
6. New London (doubtful due to price)
7. Newport
8. Claremont
9. Lebanon/W Lebanon/Hanover/White River Junction
I expect in a few years I'll know the exact responses to these choices, but I figure there must be some data points that will help me narrow things down in the meantime such as school ratings, real estate tax vs potential rent, crime, multifamily inventory, population size, other economic factors.
Even some book recommendations that talk about how to judge an area for rental investment potential would be good.
...and always at the back of mind is the lingering doubt that I should be investing in NH rentals at all given the amount of rural areas and high real estate taxes.
