Your personal need or motivation to sell should be the biggest determining factor as to timing. The Housing Affordability Index reached a new high this October at 184.2. The index is based on several factors including average wages, real estate prices and interest rates. For comparison, an index of less than 100 means it is difficult to buy.
Simply put, homes are more affordable now than at any other time since the index was created. If you need to sell now, you need to list now. You never know when that perfect buyer for your home may come knocking!
