Hi @Ann Nguyen
Have you thought about xeriscaping your yards? Many homeowners and landlords alike have converted their traditional lawns to xeriscape (xeros = dry, -scape => landscape) in recent years, both for environmental and cost savings reasons. The conversion might cost you a bit upfront, though it should eventually begin to pay for itself since it is quite low maintenance. If done right, the results are equally as impressive as a well kept and maintained traditional lawn, in my opinion. Here are some ideas for Northern California xeriscapes. Btw, since I had a minute to spare, I just called the first landscaping business I found on Yelp in the Mountain View area, "Total Landscape." I inquired about xeriscaping a yard, and the guy I spoke with pretty much blew me off. He wouldn't even offer me a quote. He also said they're booked until September.
Out of curiosity, how did you acquire your apartment? I'm on the market for a multiunit myself and am not totally convinced I should work with an agent.
