What address information should I provide when applying for a DTV visa from Vietnam without a permanent address?

Hi there! I am currently in my DTV application process and might have some questions over the next few days ☺️ I am currently in Vietnam, applying from here.

Here are the first questions:

1. What Adress Information should I put in? I haven’t lived in my home country in a while so I don’t have an Adress there. There is a possibility to enter a „permanent“ Adress and a „current“ Adress. But I don’t have a permanent Adress… so do I just put the apartment that I am staying in here in Vietnam or a postal Adress back in my home country? 😳

2. travel information: I don’t have a flight booked yet as I don’t know when the visa will be ready, so should I look up a flight that I think I might be able to take?

3. accommodation info: I’m staying with my friend in his condo - would I put the condo Adress and his contact number?

Thanks for your help 🙏🏼
