Why is it good to borrow money to buy a house?
First, who is saying that it is a better option? In general it is best to pay cash for things when you can. I think the reality is that for most people owning a house would be very difficult without some sort of financing. That said, one argument for financing a house these days even if you could afford to pay cash is that the interest rates are very low. For a 30-year fixed loan you can borrow money under 4.5% APR with decent credit. If you are willing to accept even a little risk you could almost certainly invest that same money and get a return higher than 4.5%. With the US mortgage interest tax deduction the numbers are even more favorable for financing.  Those rates look even more attractive when you consider you are paying for the house with today's dollars and paying back the loan with dollars from up to 30 years in the future, which will be worth much less.
