Immigration is looking at patterns of travel behavior. Using tourist entries to cross back & forth across land borders is probably one of those patterns.
I did take accident insurance when I got a Kasikorn account. A couple of months later I had an accident and Kasikorn paid in full. I bought more insurance the next year. They eventually wouldn’t sell to me when I turned 65.
That is what I meant by “awkward consequences” for both the owner and tenants.
The new rules actually make sense to me but the change and the path from here to there will be difficult . Similar to clearing out bank accounts opened while on tourist entries.
I signed a lease last month, fortunately with a Thai owner.
