Buying a condominium is by far the simplest and most straightforward way to own a property in Thailand. There are plenty of (new) condominiums to source in and around Chiang Mai, there is only one kind of title deed (โฉนด or 'chonod'), there are relatively few risks, and the procedure to transfer the title deed is rather straightforward.
The most important advantage about buying a condominium in Thailand is, that you can put it directly in your own name. Also, condominium law appears to be more stable than the several laws that govern companies that hold assets, such as property, a construction foreigners often use to own land and/or houses.

The most challenging matter when buying a condo is, in fact, finding the best condo that you really like, and of course .. buying it at a good price.
