Ok let me restate the question:
Right now I max my 401k, Roth IRA, and after that I can save about $700/month into a taxable account. At the end of the year I'm good for about another 8k in bonus after taxes which will also go into the taxable account.
Forgetting about income/staying put for x years/location yada yada...all of which I am aware of...how much do you dip into for your down payment? Do I need 100k before I can pull out 50k for a down payment? What is a "safe" % amount to use towards a down payment?
