Brush up on your landlord tenant laws for your state.. 

So why would anyone consider investing in Las Vegas at an initial lower return when you could buy lower cost properties with a higher return in one of the many static or declining markets?

It's not something we can simply brush off as an unsecured debt from the standpoint of the borrower and the guarantor due to its sheer mass.

@David Faulkner  some may act that way I know many truly wealthy and they were it well.. multiple homes multiple ferraris .. jets ... all sorts of trappings of wealth.. can't paint a brush and say all mega rich run around like paupers.and not all rich are are drowing in debt.. one of my business partners who sold his garbage company to waste management for 65 million... owns every thing in cash... homes in Napa valley  Tahoe  big hunting ranches travels the world.. he does wear levi's and drive a Chevy tahoe.. but one look at wifes jewelry and you get the drift.Another of my business partner owns a few hundred unit apartment in PDX all paid for... 2 million dollar home in Honolulu .. member of Wailii  condo at Nauru tower that is vacant most the time I get to use it when I visit.. drives a Tesla I talked him into buying.. so just can't paint the picture of everyone who has a bunch of toys is drowning in debt that simply is not true.

You can develop a system based on one metro area.I'd think the purpose would be to better describe a property, it will take a broad brush to paint an accurate picture and compare a parcel in Toledo with a standardized ruler so that someone in Chicago can relate to that property without knowing the Toledo market.

Piles of rock/blocks/debris, brush-piles, etc (or both in combination).

I read a bunch of stuff about people being naive and not doing it smart so I'm trying not to be in the static group!

The danger is when you wire brush old paint, the painters must make sure they have personal protective equipment, PPE, like a respirator, gloves, bunny suit, etc.

I recently had to pay a $175 plumbing bill (a child's tooth brush was flushed down the toilet). 

Just brush them off and keep going if you find they work for you.
