Quote from @Michelle Fenn: Is it just my location or are a  great majority of rental listings on Facebook Scams.   

you not on one of the major listing sites you are missing a lot of revenue potential Penny wise dollar poor

Had a few small problems but nothing major.

It wasn’t how I wanted to kick things off, but I worked with a contractor to get the bathroom fixed and functional.Once that was behind me, I focused on improving the building and maximizing income:I installed a shared washer and dryer for the tenants, a major upgrade that added convenience and increased the property’s value.I rented out the two garage parking spaces, bringing in consistent revenue.I also raised rents for the second- and third-floor tenants I inherited to be just below market-rate.

However, like @Kyle Jiron states MD allows contractors to get one third upfront at least on major rehab jobs (not on smaller jobs) and that's what at one these contractors insisted I give him as it was a major job.

If you look at the majority of foreclosure cases where the Judges make them have to show proof, the banks either got caught forging and/or fabricating the documents or claimed the notes were lost.

Even though majority of what I buy is non-performing, I just do not want to deal with it. 

Best part is NJ is not what its made out to be in terms of landlord friendly, the state gets portrayed as the entire state being bad when really most wacky laws are in the major cities and they apply to 5 units or more.  2-4 unit multi families fly below radar per say. 

Depending on the construction, you have to do major upgrades on electric, plan for plumbing for apartments which may not be permitted in the area for the sewer or septic.

And given that, in a major city, there are hundreds of houses put on the market weekly, you need a method to efficiently screen properties to make sure they won't bleed money before you spend time analyzing, touring them ect.
