We've started to look at entering the housing market and my husband and I are both torn on the idea of prepaying our mortgage and the size of our down payment.
With respect to our down payment, we are definitely putting down 25% to avoid mortgage insurance. We are questioning however, whether it's better to put a larger down payment such as 30-35% down. The opportunity cost of the larger down payment are forgone returns from investing. For example, on a house price of $300,000, we could put down $100,000 and benefit from lower monthly carrying costs or put down $75,000 and invest the additional $25,000 in the markets.
We've been pre-approved for a five year, fixed rate mortgage of 5%. From an investment standpoint, as long as we net 7.7% pre-tax, we'll have a better return on our investment with a smaller down payment. The extra down payment would leave us with monthly carrying costs of roughly $150/month, which is not a huge amount to us. Given that the S&P returned approx 15% in 2006 as well as strong historical equity returns, it seems silly to even be pondering a larger down payment. Yet, we are both debt averse, even though I consider the mortgage to be good debt. The idea of having a larger debt hanging over our heads is a bit unnerving.
Then there is the issue of prepaying a mortgage. We have always discussed prepaying a mortgage, being keen on the the idea that if we are aggressive, we could be mortgage free in 8 to 10 years. While this is hugely appealing from an emotional standpoint, we question whether it is in fact a smart financial move given the opportunity for larger equity returns.
The biggest risk I think most people fall into is that without prepaying the mortgage, people just aren't saving and end up spending the money. As long as we "pay ourselves" first, I see little financial benefit in prepaying a mortgage.
We are probably at least a few months away from purchasing a home, so we have some more time to think about it. What are your thoughts?
