This is a typical roof drain.

Unfortunately, Detroit is complex due to things being driven block by block.

@Patrick Roane, as you can see there is no clear answer, per se.That being said, if owning the property outright drains all your reserves, I would at least consider a small mortgage, so you can keep some money in reserve.  

Place good residents, make sure the block is nice (just not the street) and you should be fine.

Also a lot of side by side duplexes that are locally called "double blocks".

Something draining cash that I propose to take over and pay the owner some extra cash, that I can’t understand.  

The first project we ever flipped was only a couple blocks from our personal home.

Anyone who has to pay for good reviews, deletes any critical comments and blocks those people, and can't answer any real follow-up questions when someone digs into what their word-salad comment is actually supposed to mean (like when he tried to explain how to handle a due on sale clause on here a few months back, and made up a ridiculous answer that we all called him out on because it was wrong, then he stopped commenting), is a little sketchy IMO.  

We gutted the interior down to the cinder blocks, re-designed the unit layout to fit a more modern lifestyle.

@Corey Block You may want to talk to a few companies who do this sort of thing in your area.
