It's interesting that people spit out the usual reasons about what a great investment owning your own house is.
The usual things are:
Tax deduction
Appreciation
These reasons have been pounded into our heads by the R/E industry. We accept them as valid.
When you actually run the numbers you see how these things are not so hot. For many folks owning a home has been awful and life destroying.
People who buy at market highs get killed. Being fortunate enough to buy when the market is low is the best way but not always possible. More luck than anything else.
Owning your own home can be a great thing from a lifestyle standpoint but as an investment it's not great. Unless you get the land and house for nothing it's a luxury to own a home.
Even owning your home free and clear has costs. R/E taxes, upkeep, opportunity cost of the money tied up in the house, lack of liquidity in getting the money, lack of mobility if you have to move to change jobs.
Don't forget the time value of money and the effects of inflation on your investment.
Borrow the money out of the house? Then you owe it again and have to pay it back with interest.
Sell the house to get the money? Then where will you live? Rent again?
There are many good reasons to buy your own home but investment return is far down the list.
