Analyzing a package Deal

[KIMARD EGLETON]

Greetings everyone,

I'm reviewing a package deal right now involving 7 properties.  5 of the properties are in the same neighborhood (D-Class), one in a rural area, and one double-wide trailer.  After pulling the real estate assessor data 2 of the properties listed as just land. 

All of the homes are currently being rented (650,600,550,500,450,450,450) totaling 3650/mth, 43800/yr. After driving the neighborhood I can see that they are not in the best of shape. 

What steps would you take to evaluate this possible deal? Do you do a cash flow analysis on each property or the entire package? There are no recent comps (less than 8 mths). The owner says he doesn't want to sell homes individually. Thanks for the help.
