And fortunately for me, there was a big scandal at the building department when this was going on, all the inspectors in the borough but one was arrested for bribe taking, so everybody had to arrange "self inspection" from someone for the time being, like an architect, which my expeditor is, and send it in, though the city reserves the right to reinspect.From my perspective, if the basement is empty, or used for storage, it does not constitute a unit requiring a CO and separate meter, unless there's more to the story.

If the neighbors know you are putting a dog in a vacant home, you'll be reported to the Humane Society (and rightly so) and probably arrested...not to mention that's cruel to the dog.All of these solutions cost money, and cumulatively at least as much as you are losing as an investment. 

If you are using county records, what terms are you searching for, arrest records, evictions, sex offenders etc...?

He gets arrested 30 days later and sends terroristic threats to me and my family.... - I have had my life threatened so this tenant thing, yeah, I want to be very diligent and pick the MOST QUALIFIED

I just my agent to ask why they chose to disclose this now, so close to closing.Pulled some police records on the seller and 3 arrest since February, none of them drug related so that's good.If anything interesting comes up I'll let you know!

Was a renovated building in a C neighborhood and the PM told me they were renting units for $500 to try to attract tenants like myself (good credit, stable income, no arrests, etc.).

Then he was arrested for extortion of local businesses.

I have had problems in front of one of my locations and spoke to the major, who got me in touch with his LT, who started parking a squad car in my drive way, confiscated the pitbull, that they had tied to my fence, confiscated some marijuana, that was hidden in my trashcan, put out 'no trespassing' signs on my property, which allows them to arrest anyone that they see. 

I know people are afraid to ask questions, but you are not going to have your house stormed by HUD agents at 5AM to arrest you.

This person also has more of a criminal history than they let on, being convicted in the 2000's decade and having arrests and charges even up to 2018, some of them for things like DV, making threats, drug/weapon possession, and driving without a valid license, although on the more recent ones they may have been found not guilty.
