What is an invitation letter for a Non-O visa application in Thailand and where can I obtain one?

I am the owner of the property and in the process (with lots of documentation). Engaged an attorney. That involves Ministry of Foreign Affair to certify the translation of my Australian passport bio page (already cerified by Aus Embassy in Bangkok). Property deed showing my name, marriage certificate (already in Thai, we married in Thailand), our daughter (living now in Australia) Birth certificate (born in Bangkok), wife and my bank passbooks. Even a write up about our relationship.

After the interview at the District Office (Samut Prakan) it may take a month to get my yellow book.

Wife and daughter already have their Blue Book, as Thai nationals (they took it took it last year).

Now it is for me to get the yellow book, as a foreigner. None of us live in Thai, wife and me live in Japan, permanent residents, daughter lives in Australia (a dual Thai and Australia citizen).

Until last year, District Council said - nobody is registered as a resident for the property, in the books it appears to be owned but nobody is listed there. Now, wife and daughter have Blue Book, me to gain the Yellow book.

@Robert ********

you can own a house, but not the land.

I own a condo in Bangkok since 2008, never been on any visa, only on visa exemption (now 60 days, before June 1. 2024. it was 30 days).

@Robert ********

condos probably

@Roger ******

what you don't understand is that when in Thailand you will be applying for a 12 month "extension of Stay", not a Visa
