I'm getting more familiar with them but there are still some outstanding questions that I need answered before making any moves.

The question I'll be trying to answer tomorrow is this -- if my purchase price at auction is higher than what the lender and IRS are cumulatively owed, does the additional money above making the lender whole go towards satisfying the IRS lien -- thus putting out that red flag fire either way?  

Folks here are great to help with answers.

There are many agents out there, but it’s important to choose the right one.https://www.biggerpockets.com/blogs/5868/52724-im-new-to-investing-how-do-i-find-an-investor-friendly-agentI love answering questions if you have any!

@Andrew Y.Great answers as usual from @Brian Eastman and @Dmitriy Fomichenko  You can do it in an IRA but as they mentioned UBIT will most likely be due if you make money whether it is done in a checkbook LLC or with  the Ira custodian. 

@Lincoln Tudor:  respectfully, this type of question should be asked and answered BEFORE you go into contract with a real live seller, imho. 

I am assuming everything except gas but I am unsure and can’t find an answer on google.

This property manager could not produce a 7 Day Notice after 3 weeks of repeated requests, a worker putting in a smoke alarm saw a sewage backup and didn't even tell me or his boss, checking info for a owner payout was not entered properly and resulted in a week delay, a renter was told of a payment plan for hardship but receved a contact info update in the mail... and lastly I had to email questions each day which never got answers.

However, your original question was to pay off the house or not and we are advising you to sell, so answer to your question is NO - do not pay off but use the cash to put 20-25% down payment on more doors to offset the loss of income on the original property.

I can't really help you with the answer until I know 1.
