It's really much harder to sell a home with tenants than either vacant or with the owner, so I would be curious what you view as the benefit to you for doing so. There are many other reasons for not doing that. It's harder to arrange showing the house, sometimes tenants damage the home, or you have to do a lot more painting and repairs. While you may be betting that prices will go up in two years, you may have that idea offset by the value diminished by it not being able to be shown as well as you can present it as homeowners.
A good agent can give you a better idea of prices is your area now, and anticipated prices for several years aheand. Best regards, Terry Bell, Realtor, California
