I just ran a rental search in the MLS for zip 92127 (which includes 4S Ranch, Del Sur, High Country West, Westwood and a few other areas) and only one 3Bed/2Ba Townhome came up under $2100 in the Westwood Neighborhood. Westwood is currently zoned for Rancho Bernardo High School. You may want to look into apartments in 4S Ranch or private party rentals. It will be a bit difficult to find something less than $2100.00

I have one that is at $2275/mo and is available July 1st. Other units are condos and only one is a 3 bedroom at $1650/mo.
With only a few days until July 1st, I would encourage you to connect with a rental agency to help you find the right place. Of course check Craigslist regularly. if possible set-up an Auto search so that you don't miss anything.
Best of Luck
