yeah, it can get confusing along the way...you need A to get B, but they won't give A without B..that sort of puzzles :icon_lol:
I don't want to add to your confusing state :icon_wink:, but there is something called RU-KO for rent/lease, (RUKO means RUmah-toKO) either the toko(office/studio/bakery/whatever) in front of the living area or the livingarea above the toko. know what I mean?
Eitherway the adress is the same for both the living area as well as the commercial part of the building.
Maybe the legal side of that business-registration is not based on PMA, but on UD or PT...however it might be worth looking into that.
I have a friend (foreigner) who owns a hotel but is living on the premisses of the hotel...when I see him I will ask him about it and let you know what he said.
