Re: Max out TSP & Roth IRA...OR...save for a downpayment on a house?
in addition to the other great insight posted already,
ask your mortgage broker about getting an immeadiate second mortagage, which will likely take care of what would usually be the down payment so you are financing 100% of the cost of the mortage (maybe closing costs included as well). That way, you will not have to wait and try to save up the down payment while wasting the money on rent...
This will also eliminate the PMI (mortgage insurance), which is the same as flushing money down the drain.
Pyriel would have lots of good advice in this area...
Best of luck!
