Can I be building a house with the bank forever?
No, you can't do this indefinitely. For one, you can't just take money out as home equity with no strings attached. The cash out is done as a loan (often a HELOC) or second mortgage and you have to make payments. The lender will always make sure you are able to afford the payments. At some point, you won't qualify for the loan because of insufficient income or too many previous liens on the property. While home values often go up, there's no guarantee. And your examples are more than a bit optimistic.
