However, I came to the harsh reality that its a very competitive market for those kind of properties.

Be very careful of service animals and fair housing law, the fines are harsh.

As @Jon Holdman mentioned, it is not unusual for an owner to not have any specifics about the current state of the property if its a rental, (although providing you with a legal document exempting them from disclosure is a harsh way to express it).

If you can’t understand that I think you should get a PM.That isn’t meant to sound harsh it’s just the reality of this stuff.

In NJ under the Anti-Eviction Act, a landlord cannot impose a rent increase so large that it is "unconscionable", meaning an increase that is extremely harsh or unreasonable. 

Some make it sound like a full time job, I would say I don't spend more than 2-3 hours a week managing his property, even in the harsh winters of Boston.No LLC costs, etc.

Now, I'm not trying to be harsh, just telling you how it is: as @Brandon Turner and @David Greene say on the BP podcast all the time...the quickest way to NOT find a mentor is to blatantly ask "will you be my mentor?"

Arbitrary rules with harsh enforcement on your units, no enforcement on his own, for example. 

That may sound harsh, even mean, but it isn't.
