Thanks for posting Todd, We are in the process of ditching him, and had just hired a lawyer.

@Alex Craig  and to Chris's credit he probably realized that as well ERGO their 2 year lease program and ditching section 8 tenants all together... my other personal experience is really large homes you have to be careful with if they do require a heavy duty make ready..

You have to watch out for previous tax liens for earlier years that have been bought on the property.You have to make sure you are not bidding on a drainage ditch or a property with environmental issues.Sometimes with lenders their departments are so big they do not get the tax notice it hasn't been paid.

In a last ditch effort, I wanted to post his general numbers here and have people who are not involved evaluate them so he knows that we really are for and not against him.

Only investors buy four plexes, so they're harder to ditch if you want out.

Ditching an 8% return blanket statement doesn't fit all IMO. 

In my opinion the surge of STR in the majority of tourist markets is a last ditch effort to find cash-flow.

Tax buying varies buy state and process and interest rate and many other things have variables.Just like anything else there is competition.There are plenty of properties you DO NOT want to buy tax liens on.These are properties in a bad area where over a years time when you redeem could be worth less than the value of what you are foreclosing on.The counties and cities just want money and will sell you a tax lien on anything even if it's a drainage ditch with no value.You have to watch out for environmental and a host of other issues including taxes that were bought before yours.You can do well but just like anything else you have to research it and be smart about it.

Otherwise, ditch this, roll your proceeds through a 1031 exchange (@Dave Foster can help you) into a newer property. 

You could pay cash for a primary residence house in Dallas area which would put your monthly bills substantially lower therefore husband could possibly ditch the W-2 and focus on flipping and investments.
