Avoid these people
I lived in a building (in Pasadena, on El Molino and Cordova) run by JPRL Investments for the Hayashi group until January 2007. I was so glad to leave. As you can see on the website of the group itself, their main purpose is to buy apartment buildings, raise the rents hoping to increase the value of the building, and then resell withing two or three years at a big profit. Which means that the interests of the tenants are the last thing on their minds, and it shows. Even the simplest repair could take them weeks to do. The manager of the building where I was was incompetent (he wouldn't even return multiple calls reporting breakdowns), very rude, and treated tenants with contempt.
Avoid if you can.
