Feel free to jump in the community here and also take advantage of the treasure of knowledge here.

He is trying to sell me on Treasure Island and other beaches further north that sell for less. 

Of course value is somewhat subjective - one man's gold is another man's treasure - but RE values can generally be quantified, meaning that a reasonably knowledgeable person can take serious advantage of a person without knowledge.

Not only did they tat themselves from head-to-toe, but they also adorned their horses in elaborate metal plates, basically "chroming them out" like a biker does with a new Harley...lol.

IF the floor is off level you will need to jack it up , pour new spot footings, and install new posts with metal bases and brackets, etc.

We actually sold one of the 5 acres however it had a 20 thousand sq ft Butler metal building and we sold that to someone in the Wine business actually for Champagne Ridling machines he had invented.

I was curious if any of you have had experience with owning and renting out metal houses.

If the subsequent lienholder is aware that you are about to get the property, he may pay off your lien and wait until he can foreclose.When you foreclose, if you notify the mortgageholder (or anyone with an interest in the property) and they do not redeem the lien (pay the tax), you get Treasurer's deed free & clear.What I don't get is someone I know in AZ doesn't foreclose the mortgage so I assume he wants to assume the mortgage.Could also be the property is in bankruptcy.

It's got a metal roof that looks like it needs to be powerwashed and painted.

Definitely connect with @Corby Goade about the treasure valley in Idaho.
