The people I know with an Elite Visa bought before the price increase and love the no hassle visa. I think if you live in Bangkok they assist with the 90 reports.
I’ve got an LTR but had to do a 1 year report in June.
The only visa that doesn’t require 90 day reports is the LTR and it was specifically mentioned as a benefit of the LTR. If there is no explicit mention of a 90 day report exemption for the DTV then it is a good bet that you have to do 90 day reports like all the other visas.
Go to the Pacific Cross website. They have a page where you input your age and the give you the cost for various plans. I was just looking at it yesterday for my wife.
My Thai wife also signed our condo lease. Six years and no one ever asked to see the lease. I kept bringing it with me to immigration but they never asked.
You will have to show you meet the financial requirements each year that you extend your O visa. They will ask for bank statements and your bank book. There will be several non financial documents to submit as well.
After 90 days you extend the O visa for 1 year and you state on the extension form that the reason is "retirement". This will determine the financial and other requirement you must meet to get the extension. You can extend year after year indefinitely. Note that the OA visa also expires eventually and it also can be extended yearly.
