"As big as you can afford" does not equal every dime you have.... :-)
It is what you can afford to buy and still have enough money for everything else you need in life.
But, there is a lower limit to what a "liveaboard" boat should be. It should be big enough that it is not a "day cruiser". Because a day cruiser is designed for just that: A Day cruise, not living aboard.
Sure, there are plenty of people who have lived on 20 something footers, and there are plenty of people who have lived in their cars too. But, I would not advise doing that either.
