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

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

No biggie my bank sent me the fraud alert and I had them block the charge.

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

What they and we didn't know was the real issue was the line itself was mostly blocked some 30' to 40' away under the driveway.

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.

How do they know if this is an owner stay that you blocked on your website, and it pushed over to Vrbo?

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..

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