To be serious, whilst I applaud your desire to live away from tourist areas I think you should be aware of some of the inconveniences. Here in Juan Dolio which is apparantly a tourist area, we have 24/7 electricity. You will not get that in non tourist areas. We have access to San Pedro which has good (ish) supermarkets. We have constant water supply (if you have a well), and some OK restaurants. Having said that I live with a Dominican, my visitors are mostly Dominican, I shop in Dominican colmados, have spanish TV, and speak spanish all day long. Juan Dolio is not an endless strip of bars, in fact at this end of town there are only two, and as I mentioned you see very few tourists. Be aware that living in a Dominican only town you may miss things like internet in your home, the type of food you like, electricity, and possibly water.
You can still experience the country and the people without depriving yourself of everything.
