I am shocked at how much rents are going up. $1000 a month??!! Wow, at that kind of spike, I would still say you'd be safer buying. The woman in QA's rent went up to over $2000 a month, a good % of what she'd pay in a mortgage. Here's the story:

Unbelievable! Atrocious, but it really makes me think that the primary benefit to renting (rents logically must track incomes) just got shot down. If this trend spreads, I see no reason not to buy. Especially if I end up paying near what I would in a mortgage.
By the way, I don't agree with the assertion that you should free the money in your house. It's just a loan. I'm no expert, but the only way I see to
truly free the equity in your house is something like a reverse mortgage, which you can't do until you've paid the thing off. But a HELOC is just a loan, quite similar to using a credit card.
You're right in that the value of your house means nothing unless you sell it, but that's one of the problems in looking at a primary residence as an investment. It's so horribly illiquid that the only way to use money that's 'yours' other than selling is to leverage yourself heavily with a loan from the bank.
Many people have lost their homes by doing exactly what you described.
So if you plan to sell, or have multiple properties, a house is probably a fantastic investment. If not, it's nothing more than a place to be at a fixed cost, IMO.
