But if prices have doubled now the net cost to me is much higher. The agent fees are double what they were, and I have to pay cap gains on $500k. All that is money I have to come up with somehow in order to complete the transaction. I either have to write a check, or take on more debt. The higher prices go, the more expensive a lateral move becomes.
Yes, I have more home equity if prices go up, but that only helps me if I cash out and move out of the area.
