Do you want to buy something more turn-key or are you open to some level of rehab (more than just new carpet and a coat of paint)?

b) I was initially thinking short-term rental, which is where that surge of requests came from but it feels like a lot of work as I would be doing the turns/cleaning for most part so what are the pros-cons of mid-term? 

Replaced the carpet with hardwood floors & new trim, painted all the walls, and completely renovated the bathroom What was the outcome?

It's usually cleaning, re-painting, furniture removal, etc.

I am not sure about what you are reflecting in the cleaning number but for me 1) it is shocking what cleaners charge but it is not where you want to try to save money for quality 2) it is a pass through, the guest pays it. $250 per turn would be for larger unit and very good job.  

&1245 property aka anything that can be accelerated such as 5, 7, or 15 year property like carpets, cabinets, or other site improvements.

You can also rent Yurts, treehouses, or your own RV on the platform for more than a bare campsite, but that gets into too much cleaning and upkeep for the spirit of it.

.- $150k worth of 5/7-yr property which is appliances, cabinetry, carpets etc.This is pretty typical for a commercial property cost segregation, and I see nothing wrong with it.The problem is in the line above that, called "Selling price."

Our counsel previously advised we are legally entitled to a greater amount including all lost rent until the home was re-signed, cost of lock-out, cost to clean up house, physical damage, ect.For context, this is a solid house in a decent neighborhood and we never had prior issues with the tenant. 

But hold on to all communications with them regarding this beause if this goes ballistic, THEY have a great deal of liability in this.2) As @Nathan Gesner said, get a new Mold Remediation Company and have them go over the entire house 100% and re-treat it, then give you a written certification that it is safe and clean.3) Get rid of your brother too.
