Sally I'm trying to understand your situation: you want to lease property (land, buildings) from someone. You then want to turn around and rent said property out again?
For taking leasehold on a property you don't need a PMA - leasehold is the only enforceable legal way for foreigners to hold possession of land here in Indonesia - the active word is "enforceable".
Should you wish to lease that property out to tourists, for example, then you cannot do that as a foreigner. If you had a nominee as in for instance a freehold situation then he can do that as the property belongs to him and he is an Indonesian citizen. He/you will need a Pondok Wisata permission to rent for a small (less than 6 rooms and 300 meters area) hotel.
My understanding of PMA is that you can have a PMA company but your working range is very limited and an Indonesian citizen must hold %51 of any goods or chattels - I could very well be wrong on this though.
For me the point is that neither situation is materially different - nominee, he owns it, PMA, he owns it. Added to that the fact that you are also a woman, I presume, and the situation gets even worse as most Indonesian men will not treat you as an adult with any business acumen. That will really piss you off!
