I specialize in vacant lots purchased at tax auction for several reasons @Morris Lucas.

I purchase properties at foreclosure auction.

Which went from $14k to now $25k after it sold at auction for $220k on September 12th.

But because an HOA made the mistake and the county operated a crooked auction the purchase will just get back what they bid, $6600.  

this deal seems like a lot of risk and I am interested to seeing how it turned out.The tenants were a few weeks away from the foreclosure auction.

I purchased the property at a tax auction.

There are also deals that can be find on jud.ct.gov for foreclosure auctions but those rarely work out because the people usually owe more than the property is worth or they get cancelled and postponed frequently. 

@Jay Hinrichs I handled an auction sale years ago where the city/state had assessed a riverside parcel at 60+ acres for decades when it was actually less than 20.

the company is Tax Auction Investors and seminar solutions...i think from my research on videos etc that was or is thecompany they started as thier education company 

A spokesperson for the school said Mendenhall had not been a paid university employee but had coached as a volunteer in 2001.In 2008, he started a seminar program for would-be real estate investors called Tax Auction Advisors, according to company filings.His students there coaxed him into starting his first funds, he said in a video on the website for the seminar company, which remains in operation.
