What documentation do I need to provide for accommodation when applying for a SETV while staying in my own condo in Thailand?

First of all, big thanks and massive respect to the moderators and contributors to this group.

I am Australia and on a 30-day extension of stay after obtaining a SETV in Vientiane, Laos. The extension is about to expire, and I am about to apply a new SETV in KL, Malaysia (it has to be KL for personal reasons).

Prior to these visas/extensions, I have been on Non-B visa (and work permit) for many years, as I have been working and living in Thailand legally.

I have since stopped working in Thailand (work permit etc., cancelled), but want some extra time in Thailand to travel.

My question is that to apply SETV in KL, I have to show accommodation booking for the entire stay in Thailand (which I plan to be 90 days). But, I will be staying at my condo, for which I am on the lease.

On the official website, it says if I am staying at a friend or relative’s place, I have to show invitation letter and copy of their passport/ID Card.

But it doesn’t state what to do if I am staying at a condo of which I am on the lease. Maybe because a tourist shouldn't be on a lease?

Emails to the official email address go unanswered.

Can anybody advise me about what I need to show to meet the accommodation requirement for my situation?

Thank you!
