You really have to factor in interest rates when doing comparables now.
For example, I just ran comparables and one seller is asking $890,000, and another seller is in escrow asking $915,000.
So on the surface the $890,000 price looks cheaper. However, the one is escrow has a VA assumable loan at 2.25%.
When running the numbers I found a buyer would be paying 64% more per month for the $890,000 purchase vs. the $915,000 because of the rate difference.
So you have to consider what the rate was at the time that home went into escrow and if there was a VA or other type of assumable loan used in the purchase.
