When talking to most small banks in my area I’m running into max loan term 20 years with 6%+ interest that really kills my cash on cash return calculations even if I could extend the loan term to 30 years it would help a lot.Anytime I ask about 30 years they say they can do it but i would have to live In it for at least 6 months. 

He's literally begging me to release him from our contract so he can sell it to a wholesaler.

@David Balogun almost certainly they will not give you a release to move the property into the LLC...now will they ever find out, that's another question.   

My notes from some of the books I've read tell me to bring a Purchase and Sale Agreement (obviously), a backup PnS Agreement, some creative financing PnS Agreements (owner finance/sub2), Authorization to Release Info from Mortgage Company, Authorization to Release Info from Bank, Property Disclosure Forms, Affidavit of PnS, and a Credibility Packet to leave behind for an unsure seller. 

Find a place where the  numbers work and you aren't over extended. 

Putting in your own sweat and effort into your property is a great way to increase profit, but can also take a while and extend the amount of time until you see a return on your investment.
