What are the best tools to Analyze Properties???

[Murray Reginald]

Hi BP,

Can someone please tell me the best tools to use to analyze a distressed property? I would like to look at properties and be confident, knowledgeable and able to give an immediate offer for a property. 

Also, is HAR.COM the only website to run comps on surrounding properties because I am not a realtor but was checking to see if there is a work around?
