Same class, same era, same lease structure: Class C buildings in Western San Gabriel Valley built from 1970 to 1989 ask from $1.50 to $4.20/SF/month on Modified Gross.
On a 2,500 SF suite (about 4 to 6 exam rooms), that's $3,750 a month at the low end and $10,500 at the high end: $81,000 a year between buildings of the same class, era and lease structure. The lowest is a 1979 building that's listed as fully leased; the highest went up in 1980 and is 66% leased. The full Modified Gross list here runs $1.50 to $4.86 across 16 buildings, but it mixes seven Class B and nine Class C, built from 1922 to 2003.
The second thing to know is about location. San Gabriel Valley Medical Center is 1.5 miles from the center of the trade area. From the real estate side, a short distance to a campus is worth paying for only if it's the drive your practice actually makes. Pay for that, and negotiate everything else.
Short version: even matched on class and age, Class C Modified Gross asks in Western San Gabriel Valley run $1.50 to $4.20, and San Gabriel Valley Medical Center sits 1.5 miles out. The address is fixed the day you sign; almost everything else is negotiable. How often does your practice make the trip to San Gabriel Valley Medical Center now?
