Ok anyone feel free to correct but -
for home base, choose the place that is last government or officially linked to your official documents. Bills, letters, Tax, banking correspondence. When people contact you in your home country, what address do they currently send stuff to. I say this because If they ask for other official documents like your bank statements they may cross check where they are addressed to.
Then current , where you are physically staying for your application, near the embassy you are applying to. So neither address should be Thailand on previous tourist visa.
If you do not yet have a bank or place where you deposited 500k registered in your name and country address then this may need a 3-4 month runway to set up before finalising your application.
