It is a very block by block city depending on the neighborhood.  

I also liked the fact that it was structurally sound with concrete block construction, a tile roof, and high elevation.

And how is it “advancing society” to update the worldwide block chain every time I buy a cup of coffee and a donut?

It looks as if they hired out to H&R Block and didn't bother to check their math. 

Area, tenant use, tenant credit (i.e. only Moody's BBB or better guarantor credit).There are a lot that can vary in NNN, just like any other real estate.You have market risks: FL has another hurricane coming, CA has earthquakes and wild fires, the midwest has anemic population growth.You have some location risk: is building on hard corner with signalized access or buried mid-block with no turn lane?  

A more granular approach, in which you segment by city block or zip code, is likely going to be more helpful.I’ll use Birmingham, AL as an example since I’m most familiar with the market.

In PA, and this property is 3 blocks from N.Broad Street

I live 2 blocks away :)  I had another one in Portland proper same thing you could not get in it stunk so bad you could smell it from 15 feet away as you walked up..

thats 4200 in lost rent at 100 a month it will take you 42 months to get that money back.. and if you keep waiting it just gets worse.. price your rental to be the BEST priced one on the block the first one to get occupied not the last. this is were competition for rentals can bring rents DOWN and does. do the math..

There is a cinder block structure on it now that is basically a 1BR, 1BA shell with plumbing fixtures, but no kitchen.
