@Russell Brazil,I understand your point about DTI, but I was thinking more about the fact that we would exhaust a significant part of our savings to buy the multi-unit first and would likely have to save extensively for a couple of years in addition to what we might cash flow from the multi-unit to have enough to buy our single-family home next.

@David Falsdefinitely do not exhaust your savings.
