Corona Regional Medical Center sits 0.4 mile from the center of the Corona and Eastvale trade area.
That's straight-line distance from the middle of 17 buildings, so individual buildings sit closer or farther.

Most of the inventory sits on Magnolia Ave, Compton Ave and Main St: 9 of 17 buildings.
Here's the part that gets less attention. Landlords here quote three lease structures: NNN in seven buildings, at $1.35 to $2.80/SF/month; Modified Gross in five buildings and Full Service in two buildings. The lease read: convert every quote to total occupancy cost before comparing a single number. An NNN rate can look cheaper than a Full Service rate and cost more.
Put together: Corona Regional Medical Center sits 0.4 mile out, and landlords there quote three lease structures. Convert every quote to the same basis before any number looks cheap. When you set a quote here next to your current rent, are you comparing the same structure?
