I would second sparkey’s comments. You’re probably read enough of this blog to see what everyone’s opinion is. If despite reading this blog for 1 year, and despite delaying a purchase until now, you’re about to close escrow on a house, then I think that you’re pretty much decided that you’re ready to buy.
I don’t think that even our most optimistic realtor friend would predict a 50k-75k equity gain on your Escondido house in 5 years. I’m sure there are non-monetary quality-of-life benefits to owning that can justify your purchase.
Check and see if there’s a St Joseph statue buried somewhere on your new property. 😉
