do you know yet the limit of how much you can bring in tax free? It's not for me, under 6 months is plenty time. My uncle is still not sure whether to go ahead with the care home .

there was no way I was going to declare everything I have back home. I would never become a tax resident anywhere but my homeland where I profit from the very best nearly free healthcare, I trust my bank, my pension , and all the advantages. I would not give that up.
I've always spent around 5 months in Thailand and rented. In the days of yore I used the double entry visa, and since the 60 day exempt plus 30 days easily done at immigration. Then I leave, I think I know well the rest of S E Asia having stayed multiple times since 1984, usaly at least 10 days or more, and then re entering for another 2 months. That once a year . Never had a problem personally and have never broken any rules. Choose your visa, or not, wisely.
