Why is it interesting that it depends on life style?
Do you suggest there are fixed costs of living just because the country is very poor?
Of course it depends on your lifestyle, for both locals and expats.
A local living in a big casa, having some money would spend a heck of alot more on a monthly basis than a family with maybe one source of income for many people.
Same goes for us expats. If you chose to live in a condo by the beach in Sosua, or the capital or if you live in a smaller village etc, the expenses will change because of that.
Yes, a local citizen would get by on 5000 pesos a month, having a social net, paying no rent as they usually have owned the houses for generations, eating lots of rice, platanos and chicken, prepare food on coal when they are out of gas and having kids in public school 3 hrs a day. But it is hard for them, believe nothing else. For most people coming here from another country that is not living, it is surviving.
And then there are local citizens that earn way more, and there lifestyles and costs of living are therefor different than for the one that earns 5000 pesos.
I, even though I don?t live a "gringo life" in the sense of buying imported food or simular, can never make it on 5000 pesos a month.
The OP was asking for a 3 bedroom house near water, internet etc.
Then it is only fair to give him an estimation of the costs of that.
A person with 5000 pesos a month would not have internet, as that only is 3000 pesos a month in costs.
If you suggest an immigrant to come and live here and expect the monthly costs to be 200 US a month, then you are way out of line.
