I would sell your home if you can. I think thatis the smart thing to do. You say that you like SD, I would rent in your favorite SD area, something close to work. You may find that in a few years you can afford that home in SD that you dream of.
I STRONGLY encourage you to STAY AWAY from Tem, Mur, Winc as they are extremely overpriced too, and the commute is gonna get worse, plus gas has no where to go but up. Your quality of life would suffer. Traffic is horrible up here(I live here), and the people are getting crazy. Don’t buy into a floor plan, buy into location. But right now, don’t buy anything. RENT!
