I'd go with shared housing first. While looking for a part time Dev job. Inform the business-owner about what you are trying and that it's possible to go full-time after x months.

Set a deadline and know when to call quits. You want us to assure you, that you did the right thing. But you have the odds against you, so prepare for a worst-case.

Ps. I have multiple side projects running, profitable while working full-time.

PS2. Don't ever work on your side projects during working hours, except handling email.
