Vallejo, CA in in Northern California. Unfortunately, I am in Southern California. I would get in touch with a local Realtor. A Realtor in the area will be able to give you a current Market Analysis of your home. If possible the comps will be within 0.50 mile of your home. Sales should be within the last 6 months. If possible the sales could be within 3 months. Because home values have increased this will give you a more accurate read of approximate value. Good Luck!
