Is there a way for someone to qualify for retirement visa based on a monthly 79400 THB income in lieu of depositing 800,000 into a Thai bank account?

2 DTV questions

* I own some property in the U.S. that I rent out and manage (pay bills, arrange for maintenance) from Thailand. I have lease contracts from tenants I could show to demonstrate the income. It seems a stretch to call that income employment, What do you all think? Would I qualify for a digital nomad visa?

* I am age 66 and retired. Is there an unstated upper age limit for DTV? I plan to stay for 4 months this time. I want to set up a bank account, but don't want to put 800K baht in a bank in Thailand.

Thanks
