I might have drawn a wrong picture of himStreet, drainage, utility, and other improvements of the neighborhood commons, I generally view as a good things. If your friend does not wish to be a participant in the community he is buying into and contribute to improvements that serve all the property owners, himself included, he should really think twice about the purchase. I certainly would not want him as a neighbor.
I think he just wants to get an idea of the costs that could come up after the purchase. Since he does not plan to live there in the near future, he is not in a hurry to have the mentioned improvements done and did not calculate these expenses in the near future. He thought of having these costs later when he is sure when he will be able to build a small house there.
I think the road is also an uncertainty for him. As far as I understood from his tellings, there already is a bumpy road which is a jalan tanah and which serves his needs. But he is not sure if the neighbors would want to asphalt or refurbish it and if he would have to participate in the costs even if this improvement was unneccessary in his view.
