I'm sitting down this week to think about my finances.
One option is to invest in a house.
I'm researching the topic and will appreciate links to related HN discussions, analysis - calculations, past experiences, current market conditions & future predictions (interest rate increases et al) .... keeping duration of holding and investment capacity variable.
(especially in the bay area)
If you put down 20%, you are creating 5x leverage. Even if the market value of your house only appreciates at 2.5%, your initial down payment (the cash you actually invested) will experience 12.5% return.
Of course there are the payments too, and maintenance, etc. But you have to pay to live somewhere. So make sure you're doing an apples-to-apples comparison with renting--including the mortgage interest deduction. Make sure you really know what your investment is--the amount you're paying over renting--and calculate your return on that.
Finally, the mortgage tax deduction is not the only tax advantage to a home. Another big one is that you can keep up to $250,000 of capital gains from your home, tax free--a 15% advantage against most other investments. Again, make sure you take that into account when comparing.
All of the above are only really advantages if you live in your house for a while. I agree with the other poster who said it's probably only worth it if you plan to live in that home for at least 5-7 years.
