Walking for Dollars - using my day job to learn the area

[Account Closed]

I just got a job as a door to door sales person. I am very excited about my new job and feel that I will love it, grow in it, and be successful in it; I can see myself in it for the long term, working my way up in the company. However I still have an interest in real estate that I can't shake. As I'm walking through all these residential neighborhoods I'm getting a feel for the city I work in and I'm seeing a lot of vacant properties and hearing a lot of "oh I'll be moving soon.". Obviously it would be inappropriate and against company policy to knock the doors and start talking about if their interested in doing a real estate deal with me, but what I do think I can ethically do is simply learn and observe potential opportunities and be able to physically scope out properties while simultaneously holding the best interest of my boss in mind. What should I be looking for when walking through all these neighborhoods, as a newbie? I've never executed any real estate deals or gotten anywhere in it, but I see an opportunity here. If I want to buy, rehab, then rent out these vacant beat up residential properties I see, while having the newbie low-paying entry level position in the company I work for, what can I do to take action? What do I need to know? How do i make use of walking-for-dollars?
