Based on the comments with
@Stuart ********
(who advised u correctly) you are confusing 2 very different scenarios:
1- u get a SINGLE 90 day Non-O with the intent to then EXTEND inside Thailand.
In that case u will need the 400k in ur account for 2 months, bla bla...
Then they extend those 90 days to 1 year.
In THAT case if u ever leave u need re-entry(s) and u also need to do 90 day reports.
2- u get a 1 year multiple entry visa.
That gives u a window of 1 year to come in/out as many times as u want... and a max stay of 90 days at a time.
No re-entry needed no 90 days reports.
(TM30 applies for both scenarios)
With option 2 u could get up to 17 months out of that visa.
If u leave and come back on day #364 u would still get 90 days as the visa is still valid.
Thats 15 months.
Then an extension inside TH based on family for 1900 baht.... another 2 months.
Whether scenario 1 or 2 depends.
Most of the people that use option 2 is cuz they dont have the 400k... OR.... they dont really live in TH. Just come here often... so the whole no-90 days no-reentry is great for them.
Option 1 is more convenient if u do have the 400k and plan to live in TH most of the year without having to leave every 90 days.
Also: i would strongly recommend Ho Chi Minh instead of Savanaket
They do NOT check financials, very few people, and a GREAT city to enjoy while waiting for it all to be done.
Same turnaround: 1 day hand in..... if anything missing they will tell u (nice people at thay consulate) if all OK they receive all and 200USD
Next day pick up after 13hrs
