I have a small resort/apartment/bungalow with 8 units in differents sizes.

I like to seperate the units and sell one by one.

Falang can not own Land only apartment.

I have title books for all unit

Can I seperate and sell them with out any land and make the land as a commen aria for all houses, so Falang can buy.

Why not make the plots small, lease the plots and sell the buildings, keep the common area as a seperate plot.

I have recently seen adverts for a small (total 30 units) upmarket development in Phuket, on the road from Kathu down into Patong, which has a mix of 2-storey townhouses and apartments and which seems to be doing exactly what you describe. They say that, because it's all set up as a condominium, a foreigner can legally buy and own the freehold of one of the semi-detached townhouses. See their Web site (www.thecrestphuket.com) and in particular go to the 'downloads' and look at FAQs.

The problem with setting the development up as a condominium is that you can only sell 49% of the units (by area) to foreigners. Another way to do it is to sell the unit to the foreigner (as foreigners can own the actual buiding located on the land) and then lease out the relevant part of the land to the foreigner via a long term lease.
