Learning how to properly analyze deals is key #1.  

Here's how:In most larger cities, there is usually at least one CPA firm who's main function is to fight for property tax values.

If you mean the mortgage underwrite, it needs to be a complete and functional home with no apparent health or safety issues.The bathrooms can be old, nasty, and gross, but they must be complete and functional. 

I bring a cheap (about $8) electrical tester that you plug into an outlet, to see if the outlet is wired properly.  

The question though that needs to be asked is: If you are a real estate professional and tell a seller they can get more to properly market their property then why would they agree to wholesale it?

Sorry, I was trying to understand exactly what you are asking so I can give a proper answer... if I have one lol.You can always use the deal calculator/analyzer provider on the site to check if it seems like a great deal.you can find it here  https://www.biggerpockets.com/buy-and-hold-calculator

Most will not have proper structure to the actual Mortgagee.  

He's been in court for a year,  is pro per (no lawyer), but seems to have the blessing of the judge on his case.

She could respond that she wasnt given proper notice.

The only way this trend will continue is for buyers to properly do their own due diligence and stop overpaying for properties that are NOT deals.
