Good suggestions above.
I would highly recommend getting a metal roof. With minimal care, it will last the rest of your life. My parents have cheap galvanized sheetmetal roofing on their house which was just nailed on. It dates to the 1940s and we just paint it about every ten or so years with aluminum paint and replace any loose nails with screws.
My parents got their first geothermal in this same house in 1990. That unit finally needed replacement this year. The newer units are more efficient and should last longer too. They run a wood add-on and any time it is below say 25 degrees they burn a little wood just because it feels good. A big part of the expense is the loop in your yard but this only has to be done once. There are also incentives from the government and sometimes your power company for going with geothermal.
With stone houses, the biggest enemy is water. It must have a good roof and water must be kept out of the walls so the cement work around the stones must be maintained. Snakes also like to go up through the walls if they are not totally solid and lounge around in the attic.
One tip I'd like to give is to keep the interior of the home somewhat historically correct. First, it is simply tasteful and, second, it can help with the homes value. The millwork can really set it apart too.
