the number of properties isn’t important but the income/profit of your business is. ;)
In my particular case,I also buy, renovate and sell a property from time to time. I’m quite sure that Thai authorities like my tax returns a lot more than tax returns of most freelancers/influencers.
Also don’t forget that not all DTV holders want to live (almost) permanently in Thailand. Many are like me, having a property in Thailand and want to stay here part of the year.
