You should rather say: "I suppose it depends on your type of business. If you are a B2C and you need lot of traction before charging customers, the answer may be yes."
Family and Mortgage should not affect your choice for bootstrapping.
If you're a B2C that can't charge customers until you've gained a lot of traction, you should get no investment. How many times does this la-la-land "business" plan of "pay nothing, get everything" have to play out before we recognize it's not a business at all? Facebook is not profitable. Twitter is not profitable. Google's fundamentals are questionable (AdWords is a ripoff), and they lucked out with Google Apps for Business and other sources of direct revenue which similar companies have yet to replicate. And those are the "successful" free products.
Those are relevant factors too, surely. But you have to relate to the reality that you are in. If you have a high burn rate and no way of lowering it considerably, you have to take that into consideration.
