Buying directly from owner using their debt

[Sam Stolt]

I am the opportunity to buy an off market deal at a nice discount. Buying from owner and keeping his debt in place for up to 2 years. 

Is there any ideas for setting up a mechanism to auto pay his loan or different structure ideas?

I will be bringing in a partner for construction on this one. Two ways of doing that i want to hear pros and cons too. Adding him to the title while my interest is in an LLC. Or adding him to the LLC i set up for the property. So adding him to title or to LLC?
the only thing ill hold in this llc is this property.
