Yes, this is a common course of action among tax deliquent property buyers but I have never been successful for the following reasons:1) You have to research the deed to the property and ensure all owners are identified and sign the quit claim deed.  2) Contact the IRS (or have a real estate lawyer do so) and find out if there are any outstanding federal tax liens on the property.3) Contact the local county and city officials to get a list of all civic liens other than taxes due. 

Had them going for 5-10 years with great success - under 2% vacancy, 6% cash on cash, nice mild appreciation, outstanding tenant references as to our responsiveness, etc....

Check to make sure all the contractors who did work on the property were paid, no outstanding utilities due, and the taxes have been paid to date.

There are many national footprint QI's that can help you since 1031 is a federal statute applied the same way nationwide with a couple of little state additions. 

@Jeremy Clendenin I would check and make sure there no outstanding liens on the property if there’s an HOA You’ll want to know that number or fee and if the HOA has a lien against the condo, Who knows maybe the previous owner didn’t like the HOA so he never paid his dues ?

While I understand I am responsible  for verifying all information,  I will be curious to see and the response from the turnkey provider who prides himself in outstanding customer service .
