The company way would work, albeit at additional costs, complexities and uncertainties. Why risk investing money when you cannot control the asset / itβs use. Just rent. Worry-free and mostly ends up cheaper. Plus more flexible.
To my knowledge one can get married in any of the the 878 amphoe(s). Like with immigration and all the other federalist, overly bureaucratic acts in Thailand, where every local bureaucracy makes their own, deviating, ever changing rules on the fly (because some little big sheriff there just decided to do so): Just check with a hand full of different offices and pick the one that gives you the least trouble and unnecessary work. Good luck.
Sounds doable. I always have applicable health insurance (this requirement may even be there to stay). And the Thai Pass will likely be gone soon. The only annoying part is to head to a border every 60 days. But I am sure this can be made fun by combining it with motorcycle tours into the various neighboring countries.
Might do that this year. Was hoping for the new LTR visa (as I would qualify in basically all its categories), but is seems this isn't moving beyond talk and empty promises once again, unfortunately.
Open a Wise (Multi Currency) account - which gives you several international bank account numbers for free. Use Deemoney to transfer money from Thailand to it. Then use that Wise account to exchange or send money anywhere, including New Zealand.
Just like with almost every overly bureaucratic institution in Thailand, you can go and shop around for more favorable conditions. Just check several Amphoes until one gives you decent favorable conditions. I do the same with immigration.
