It sounds to me like you’re not financially prepared to purchase that house.
I would never leverage myself that much for a material purchase…perhaps surgery for a family member or spouse.
What money would you use to fix up the place after the purchase? HELOC?
Given the dearth of rentals on the market, I think you should hold off. The SD real estate market is going to flounder for a while, last year it was up, next year it’s going back down. And interest rates aren’t going anywhere for a while.
