What are the requirements and recommendations for applying for a Thai non O-A visa concerning funds and documentation?

Hi All, I'm new to the group.

I’m applying for a Thai non O-A visa. [members only]

One of the requirements is to provide a ”Recent bank statement for the last three months showing the applicant's name and ending balance of no less than $30,000 or proof of monthly income of not less than $2,500/month) along with the current bank statement showing incoming income”. I meet the $2,500/month requirement, though I only had the $30,000 for two months.

The doubt is that I usually keep the vast majority invested and not in a bank account.

Would it be beneficial to include a formal document from my investment account that indicates the total amount invested? The amount is significantly higher than the requirement, amounting to 800,000 baht.

Should I wait an additional month to submit my application?

I already rented a place to live. Should I provide a copy of the documentation from the home lease?

Is the application process based solely on uploading documents to the website or are the documents mailed to the embassy?

Thank you in advance.

PS: I already have Thai health insurance, completed the background check, the health certificate, a copy of my passport, and recent photos. My lease starts August 15.
