I don't want to hire a collection company who sends out one or two mail to the company or just make one or two phone call and close the case.

Then call the top 3 and explain your investment strategy and find out how they get their properties on to see which agent will best fit your strategyThen the other parts come next (inc property management, lenders etc)Shoot me a message if you need any advice or have any questions

We used to call it "four corners" and when we were kids we'd ride our bikes (I guess it would ahve been the south east corner?). 

Since the property is located so close to you, and you already know that it is vacant along with recent history, I would try to locate the home owner's phone number and call him or her directly.

It really comes down to your personal preference of how much you need the face-to-face interaction, maybe video call may do for you.

I called the city and they said that they do plow the snow in that alley since the alley is actually marked in the city as a street.

When it comes to Hard Money Lender I would just schedule a call and start filling in the blanks.

I am about to close on a rental property there, I did my research and a company called 'MPI Property management' seems very good.

A good performing note will realistically not have the due on sale clause called.

That being said the $100 to $200 under market is not really what I would call "slightly" under market.
