It can be the location: such as nearby public transport, nearby certain schools or collages, close to the supermarket/ shopping mall, couple of minutes drive to the downtown, nearby a park, and so on.

We acquired a listing on a triple net supermarket building being sold for about 40% below market value - in all my years I have only seen something this discounted listed one other time.  

Of course accidents happen but the probably of being the victim of a crime isn't higher than if you go into a supermarket in the US and risk being the random victim of a mentally-ill mass shooter.

Up until about 9 months ago, I used only craigslist and posted flyers on billboards outside supermarkets.

It was a furniture store. 17,500 square feet inside, .57 acre lot, parking right in front, but not in back so not ideal for a supermarket unless interested in buying the lot across the street (traffic study required).

My experience has been that it is very difficult to quantify price appreciation and the time necessary for it to affect the value of your property; in general, a big commercial development like a mall or a big supermarket will help but it is really difficult to get the timing right. 

It's not far from major avenues, but definitely not too close, and the mall a few blocks away has a Starbucks, a Chase bank, a CVS, and a supermarket.

Both cities have private projects featuring new shopping malls, cinemas, and supermarkets.

He rented to one that found Manhattan rents ridiculous, especially after 09/11 there was great demand for office space in Manhattan, so many Manhattan office based business moved to Queens, and even stores that's been vacant a while were rented, even a store that formerly housed a supermarket quickly became an office hub.Then, he had a barber shop tenant, whom he evicted, and left behind a fully equipped shop.

I like local gas stations, super markets, and neighbors.
