Spencers crossing is a new and developing area like Adam mentioned. The only thing about these new developments are the Mello Roos and Special assessment taxes that will bump your payment up. If you are considering this area. I would recommend crossing over Winchester Rd, and you can apply for USDA 0 down loan, and move into an area that is part of the Temecula School district without the sticker price.
You can check your eligibility for USDA loans and other programs here.
