We own both a mortgage company and a real estate business, we do a ton of real estate investor deals, and, personally, my wife and I have flipped or built dozens of homes.

@Jeremy MahoneyThese are very personal questions that require more info to answer properly but below are my answers.

Personally as someone living in Old City the many developments along Christopher Columbus Blvd, and the capping project along I-95 near present great opportunities in the future for new shops and restaurants.What are your thoughts!

A great way to network and meet people in your local community is to attend in person meet ups.

I personally would give all of my complaints and responses to prospective tenants, but whether that would protect you from liability I have no idea.might want to contact your local newspaper about the lack of city response. 

I have a separate computer set up for QB that I don't use for personal stuff.

Sorry I couldn’t figure out how to reply to each person individually. 

I'd think even where sub to or seller financing is most common, maybe the markets where it happens the most, maybe it achieves 2 or 3% max.The few times I see it in our area personally, is almost always on a 5-10 unit non-performing asset that someone can't get a loan on because of the debt coverage requirements.  

An old person who just lost their spouse, a person in pre-foreclosure, someone going through a divorce, and an absentee landlord all have different levers to pull.

A few ideas for lead sources:Drive for dollars, then cold call the list.Get a list of houses in foreclosure from court.Try to get the "hard to get" lists (ie, where you have to go in person, not available online).
