No visible visa then you have no visa. Minimum should be written confirmation on Thai letterhead Ed paper. You get the stamp in the passport on arrival. Call the agent now
You can have a 30 year rolling lease x 3 ( 90 years) if you buy new or take over a lease. Fre3hold as stated will have to be Thai owned or Thai company owned (min Thai is 51%)
I keep my old UK bank, added Wise account which has a UK address too. Transfer sterling to Wise, convert to Baht and then send to you Thai account. Works like a dream.
Every transfer to Wise can be automated, conversion automated and even to Thai account automated.
