Association
The entrance has a staffed guard gate. Recent listings show association dues of about $575 a month. Ask for the CC&Rs, budget and reserve study early in escrow, and confirm the dues for the specific address.
Schools
Mountain View Estates is in the Las Virgenes Unified School District, which serves Calabasas, Agoura Hills, Hidden Hills and most of Westlake Village. The closest campuses are Lupin Hill Elementary School (about 0.8 mile) and A.E. Wright Middle School (about 2.3 miles). Attendance is set by address, so confirm the assignment for a specific home with the district.
What to check
Pull the permit history, check the roof, HVAC and plumbing for the age of the home, and look up the CAL FIRE fire hazard severity zone for the address, since much of Calabasas is in a very high fire hazard severity zone and that affects insurance and brush-clearance rules.
