I made a spread sheet comparing renting to buying a few years ago. The premise was that I wanted to compare my investment in my home vs. paying less to rent and investing the difference in the stock market. The assumptions were something like a 3.5% mortgage rate (30y) and 4% appreciation on my home, vs. a 7% appreciation in the market.

What I found is that on a time horizon of ~7 years, it absolutely makes sense to buy a home. The reason is that when you have a mortgage, you're making a highly leveraged investment. If you buy a house for 100k and put 20k down, then you're 5x leveraged. If you're able to sell the house for 110k. The price has increased 10%, but your ROI is 50%.

There was a definite inflection point after 7 years, however, where the amount of leverage decreases to the point that the higher gains in the market begin to dominate the modest increase in home value.

Did you include closing fees?

Those can take a big chunk out of the appreciation when you sell and buy, and could make a difference of not breaking even for an additional year or two.

Yes, fees were included for selling the house, but I did not include capitol gains taxes in the investment calculation.

You can lever up an equity portfolio as well. Moreover, the going interest rate for a margin loan is only 1-2% (less than the cost of a mortgage).

Although mortgages have some big advantages:

1. Interest rate can be fixed for 30 years.

2. Interest is tax-deductible.

3. No margin call. If the price drops, you can wait until it recovers.

There’s really nothing similar available to the average person for other investments.

Is that the going rate for a margin loan? I have only found IBKR to have rates that low.

Can you just take the equity back out of your home and put it into the market?
