One of the best things (almost nobody does) is to spend a few hours and mystery shop your competition - pretend you are an interested aplicant and call, ask questions, see if they do open house type showings.

It's no great economic mystery that increases in property taxes will be paid by the landlord in the short term and the renter in the long term

Murders are common and average 1+ a month.

If it's a buyer who seems cool and just wants to talk turkey in order to get a deal done, I'll sometimes tell them just to get rid of the mystery, especially when I know I have other buyers anyway.  

Mysteriously, all my colleague/follower numbers suddenly updated today.

Do you know what's the murder rate in New York or Los Angeles?

If it was a brutal murder, I might think twice....but then again, I don't think I would ever ask if anyone had died in a home, before putting in an offer........and everybody's gotta die somewhere!  

Foundation cracks, horizontal or otherwise, tend to be more troubling when there has been movement of one, or both sides of the crack/fault.If that is simply parging over brick, it is also possible your crack is a washed out mortar joint between two courses of brick - then you have a new mystery to find out from where came the water.Is the inside face of the foundation wall visible?

Federal and Atlantic area there are crimes nothing major murders or the like but did find  theft , stolen vehicles, but like everywhere a lot of sex offenders 

They disregarded the legitimate reasons for needing to inquire about the mystery truck.I see 3 reasons for needing to ensure the mystery person is or is not using that unit as his/her permanent residence alongside the signed tenant:Criminal -> evictionAdd'l wear and tear -> rent must go upIf the signed tenant leaves and the other person stays behind they aren't on the lease -> no legal recourse.Actually, there is always legal recourse.
