"Getting a mortgage for the interest write-off is like buying packs of baseball cards for the gum."

That said, I'd refer you to The correct order of investing as much of that question really overlaps with this.

This question boils down to priorities, the best use of the funds. There are those who suggest that a mortgage brings risk. Of course it does, just not for the borrower, the risk is borne by the lender. Risk comes from lack of liquidity. Say your girlfriend buys the house with cash, and leaves little reserve. She loses her job, and it's great that she has no mortgage. But she does have every other cost life brings, including a tax bill that can turn into a house getting foreclosed on.

The details that you didn't disclose are those needed to look at the rest of the "priorities" list. A fully funded 401(k) with appropriate balance, and no other debt? And a 1 year emergency fund? I wouldn't argue against buying the house with cash. No real savings and passing on the 401(k) matched deposit? I'd think carefully about the longterm impact of the cash purchase.
