Determining Class of House

[Latanya Richardson]

does anyone what factors are used in determining the "class of house" when purchasing property?  I am referring to the following article:  

Ultimate Rule: Better Tenants = Fewer Management Problems

The ultimate rule to help you reduce bad tenant situations is to lease to better tenants in the first place. Even the best property manager can only play the hand they’re dealt. When you lease to a problematic tenant, you will get problems.

In contrast, when you secure a great tenant, the need for management and the hassle associated with it goes down dramatically. If you want to get better tenants, you must do two things:

1. Buy higher quality properties.
2. Have a solid tenant screening process.

The quality of the rental property is the largest predictor of tenant quality. When you buy a property in a C, D, or any-of-the-subsequent-letters-that-follow location, you are also making a decision about the types of tenant you will attract and the level of management required for that tenant. 

THANXS!
