Non-western passport that gives you 90 days in Thailand, huh? We might be from the same land, or vecinos at least
That makes sense if you can use your old Ejari somehow. But remember that using fake bills has its risks too.
A SEA address can be completely legit, since you'll actually be renting and spending time there, and so nothing would be fake. A lot of banks accept ED visas, Thai Elite, etc.
Plus, many banks don't even ask for any of that, they just want to see a lease agreement, utility bill or a local bank statement. It depends on the bank and the country too.
I think that if you want to keep your UAE residency though, it comes with its advantages too, so your setup looks solid enough.
Also, remember that you can have multiple residencies anyways, so you can try opening personal accounts in different countries and in some of them use your UAE address, in others try to see if you can use a SEA address, and so on. This could help you learn a thing or two in case that you need to do some modifications to your setup in a few years down the road, which you'll very likely need to do, since you'll outgrow the setup eventually.
