I moved from Franklin Park ( well water) to Robbinsville ( well water, septic & propane heat) & from a personal experience can tell you that these are the things to keep in mind:-
1. Well water- When you buy a home with well water the NJ PWTA act requires well testing by the seller - A clean certificate should reassure you of the potability & quality.
Personally it tastes sweeter, is naturally cold & you know there are no chemicals being added without your permission that could potentially be harmful( chlorine, flouride, etc.)
No water bill either :-)
2. Propane gas- The usage & how well the home is insulated is the underling cost determining factor.
You can have an above ground or buried tank that the gas co will drop by & intermittently fill up without any inconvenience to you.. Not any different from having natural piped gas.
3. Septic :- The age & maintainence of the tank is key here. Have it pumped every 2-4 yrs & you should be fine. We don't dump oil down the drain, don't have an in-sinkerator.
Other than that its all just common sense.
A septic testing is recommended if buying a resale & can be done at the time of the regular home inspection.
Working wiht an agent who is familiar with degrees of problems that could arise regarding wells & septics & potentially how much they might cost you , when to take a seller credit for these & when not to; & one who can put you in the hands of the right inspectors/ repair contractors is very important as is the attorney you work with.
Overall, if buying in a more rural area or one that wants to maintain its low density character , you'll find homes with well & septic.
Taking the right precautions could give you the home & the lifestyle you are seeking.
