167K -> 15 years ago , 330K now. Lets assume it is a double and the price is 167 * 2 = 334k
Using rule of 72, the annual rate is 72/15 ~ 4.8% per year
Using Excel spreadsheet, the return is 4.75%
So, this is a return of 4.75% per year. Is this good??
Please noted that I have not factored in the interest that you parent lost to the bank for the housing loan. If you take this into account, the return is not even FD rate. How about the money that your parent sunk in for renovation?
In general and over the long run, the housing price is only going up as much as the GDP rate. This is common sense. The price of the house can only goes up if people can afford to buy it.
Buy a house to live is not an INVESTMENT. 90% of the time, you will lose money when you sell your primary residence. It may serves as a good inflation hedge. You do it because you want to live in that area. And, there is nothing wrong with that. But, do not kid yourself that it is an investment.

Good point. But what you have not factored in is the hidden profits. If his parents did not buy a house, where would they be living then....somewhere rented I suppose. Then they would have to pay rent. If you take into account the rental saved, what would be the returns then? There is nothing more comfortable than living in your own home. Renovation or not, that is besides the point. You can never renovate if you live in a rented place!
