If you rehab a house in one of the neighborhoods you're considering will it be surrounded by other abandoned distressed properties or are these abandoned properties located in decent neighborhoods that people will want to live? 

Sounds like I should open a location there, I would make a KILLING!

Here’s how to take it further:Follow up consistently - If someone responds, follow up every few weeks to see if they have new deals that fit your criteria.Be specific - Clearly outline your preferred property type, location, condition, and price range to make it easier for wholesalers to keep you in mind.Build relationships - Try setting up a phone call instead of just texting.

Go for higher quality properties in better locations as rental properties are priced for risk.

I'm in Chicago and was just curious where your 4-flat is located here?

I also have been talking to a property manager and asking for insights/advice for the location. 

Central location of everything for you, not having to keep track of things in multiple places.

I would start with the Fair Market Rents (FMR) in the county where the property is located and use that as a basis to negotiate from there.Thanks Jaycee, are to referring to the HUD website? 

These were custom homes & when the subdivision grading was done we did not know the size of the homes nor their driveway locations.

You could offer to split it 50/50 or have them pay, but I'd make sure it is professionally done and the vent is put in a good location.
