Welcome to the forum. I will have a go at your questions...
insectsonline wrote1. Without a KITAS, can I still get a PW? I am thinking yes as the PW is in the land owner's name and not mine (as the foreigner) so my residential status is of no consequence. Can this necessity of needing the signature of the land owner come with another set of issues? Can they leverage off that?
The PW will be in the land owner's name so as you say your residential status is of no consequence, as in effect the land owner is also the business owner. The person will also be liable for taxes on the income of the business. So obviously you will need to work closely with this person if you go ahead with this.
insectsonline wrote2. Is it correct that running the villa business without having a KITAS I will be subject to 20% income tax, whilst if I had a KITAS the tax would be 10%?
If you are talking about setting this up as a business with a working KITAS, then you need to set up a PMA company and so forth. It's not cheap and probably not worth your while if it is a single villa.
insectsonline wrote3. If the villa was run with a PW which has now expired, is it not common to have difficulty renewing the PW? Can they just decide not to give your another one and leave you in limbo even if you have a rental IMB?
In my experience renewing the PW wasn't much of a drama. The first time we renewed ours, we discovered it was still in the previous owner's name, so that had to be changed. We then added some more rooms so had to change to a melati licence.
insectsonline wrote4. Would they still issue a PW to a villa which is currently in no fit state for rental? I ask this because I hesitate at purchasing a property for rental purposes which has no, or has an expired, PW. Especially when this villa is very run down.
I am not sure exactly. There are many hotels in Bali that would be considered 'run down' but they still have a licence. The government does come and check your property. About 20 people in 2 kijangs will show up and you need to cook them lunch.
insectsonline wrote5. If the villa already has a valid IMB, how long does the application for PW usually take? I understand there is some greasing of hands involved to make it shorter, so what outcome could I expect in both scenarios - 1. no greasing and 2. greasing.
I live in north Bali where getting licences like this seems very easy. But you mentioned Seminyak, where I have seen people complaining on FB that it is taking years.
Unfortunately there are some scammers who take your money to get the licence and just keep your money and when you ask after the licence they say it is still processing.
insectsonline wrote6. From research I've uncovered PW prices estimated anywhere from 20Bil IDR to 120Bil IDR. What is a more accurate price for a Seminyak 5 brm villa (I am not sure if the size matters. Does it?)
You mean 20 million?
I have a friend here in north Bali who does nothing but licences, hotels, convenience stores etc. I don't know if he would do it for Seminyak but could ask if you are interested.
