I've been looking at houses in different areas on Realtor.com and also viewing the crime maps on spotcrime.com as well at neighborhood scout.What I seek is a SFH or small multi-family unit with good cash flow.

You will incur taxes in the scenario you describe.       

@Doug Pretorious has been investing in lease / purchase options for some time and could provide you a better view of what you "can" do without traversing too far into grey areas.

Recently I've headed a group of  Chicago BP   investors that go out every Saturday to view properties and make offers using no money down lines of credit.

You can see the bird's eye view of this property on Google Earth by looking for the intersection of Lamb Ave and Roberts St.

Being a part time realtor is possible, most clients I have had work 9-5 and want to view properties on evenings and weekends.  

I began the process of advertising the rental and giving the tenant adequate notice when someone wanted to view the property. 

It wasn't a match needless to say for several reasons.What you describe is what I'm looking for to get help that is not otherwise being provided with my current agent.

In the beginning it's only the offer so you're negotiating from a different point of view.
