Can it be done

[BlibbityBlabbity]

Well I think you need to address a couple of other issues:

What limits are you thinking you will be laying to generate this income (or what are you interested in)?

What kind of PROVEN success have you had (and at what limits/tourney levels)?

You will want to get PokerTracker immediately and start tracking your play.

Is there a possibility for part time work for you (personally), if so, you can start building up a bankroll that will cover your current salaries for a YEAR or two to give you comfort and confidence that will allow you to play your best game and not be concerned of "losing the rent money" during the play of a hand.

There is a book, I am about 3/4 through it, which IMO is EXCELLENT in walking you through this decision....

Professional Poker: The Essential Guide To Playing For a Living
By Max Blade

If you haven't read that I would suggest starting there.

In short, the answer to your question is YES, it is POSSIBLE. I think now you need to decide if it is the right thing for you.

Good luck
