It is not uncommon for me to find tenants with 700-800 credit scores, which mitigates my risk of needing to evict to almost 0. 

In the title claims I've handled, and admittedly they were complex, several years to resolve the issue were not uncommon. 

I work with and frequent investor group meetings and have my finger on the pulse in KC market.I can't speak for the other 4 mentioned markets, but for KC, it is not uncommon to find 7.5-10% cap (turnkey) rates in both SF/MF.

Also from what that investor told me to get bought out they had to take a cram down.. which again on its face is not a crime or that uncommon.. early exits it can be common just like cashing in your CD early.. but what I saw was notes were due and they were still getting asked to make concessions..

This not uncommon with tax sale lots, many are unbuildable for one reason or another.  

It is not uncommon for investors who want only interest income to simply stop paying the taxes and let the property go to auction again if nobody redeems. 

However, I don't think its that uncommon, and in fact it actually shows you are staying with a savvy host who likely knows what they're doing. 

It seems super uncommon for high paid individuals with good credit to do something like this.

Is this uncommon?

It is not at all uncommon,, married or not, to have a primary wage earner, and one or more secondary, regardless of the makeup of the group.
