If you come across any attractive sloped lots have a topo map in hand as you walk them. With a little clearing it might be a possible to find a hidden view to the mountains or over water and that is a luxury that never grows old.
Also a lot that doesn't have power lines nearby shouldn't be automatically discounted as too expensive to develop anymore. During the last 3 or 4 years off grid solar equipment has developed to the point where it is actually often less expensive to install a system rather than running private power lines. The

Kohler RES systems NH Solar favors can easily fully power a 200 amp service, are maintenance free, carry a 10,000 cycle (27+ years!) warranty on the battery, and will provide you with reliable full power ...and zero electric bills.
Even if you are going to be grid tied consider installing a good woodstove in the basement and pv solar to really cut back on your heating and electricity expense during your retirement years. It is not unlikely that you will see occasional power outages so be prepared for that with an essential loads generator or better yet a battery backed up solar system such as the
LG/StorEdge system. Whole house automatic generators are wonderful but they are only single purpose and very expensive to install and maintain.
As you explore the different towns in the area be very aware of large 501C3 non-profits and State owned land, both have the effect of raising the tax base on the residents and will have an adverse effect on your long term tax expense. Tuftonboro is ok, Moultonboro golden, and New Hampton where I live ...not so good
As far as a realtor goes, the first one I'd call would be Nancy Deporter
