I was reading this post on Blueprint for Financial Prosperity and it brought up several thoughts which I’d like to share.
The article is about paying a mortgage bi-weekly rather than monthly, so you end up making one extra mortgage payment a year. The thought behind this is that the extra payment will drastically cut the life of the mortgage.

Consider a 30-year $200k fixed 7.00% mortgage starting in December of 2006. If you make one extra payments every December, then instead of the mortgage ending in December 2036, it will end in December of 2030 (if you make two extra payments a year, it will end in March 2027).
Now, this is obviously a tremendous savings, in the case cited above the savings is almost $100k. In the case of a primary residence, people like the notion of freeing up their cashflow early, so that they can use it in other ways, like a personal safety-net or to invest elsewhere. I think in this case, the peace of mind that people get from fully owning their house is certainly valuable.
However, how does this strategy work for investment properties?
Let’s say that I’m renting an apartment out for 2k a month, but my mortgage payment is only 1k. Is it better for me to use the extra money to pay down the mortgage, or is it better to take that money and invest it elsewhere? Surely if you highly doubt that you’re not going to be able to make anything near 7%, it is better to just pay off all of your mortgages.
The point of the investment property is that it’s an investment. What if instead of paying off the mortgage, you save the excess rent until you have enough money to buy another place on which you will also have a positive cash flow (by design, of course)? You’ll then be collecting positive cash flow from two properties, which you will then use to purchase another eventually. All the while, you’re paying off the mortgages of your existing properties. Instead of keeping all of your equity tied up in one place, you’re using it to grow your investment. In 30 years, your first property will still be completely paid off, but you’ll also have other properties that are almost paid off as well.
If you use the extra money of an investment property to pay down the mortgage, in 30 years you will have one house that is paid off, 100k, plus the rent collected over the last 6 year period, but I don’t think it compares.
In the second scenario where you buy other houses with the leftover rent, there are tax advantages plus you will benefit more from appreciation.
You’re certainly leveraging yourself more in the second scenario, but I believe that it can be done in a responsible way according to your tolerance for risk. Maybe you’ll want to wait 5 years before purchasing the second property because you want to have a large safety net before investing again. As I’ve said elsewhere on this blog, it is important to make sure that you have enough money to cover problems that will arise. If after you pay a mortgage and allot a percentage to maintenance and vacancies you still have rental profits left, I believe it would be wise to save that money and invest it elsewhere.
What do you guys think?
