Placing Multiple Properties In One Contract

[Levi Bennett]

Hey guys, I'm a wholesaler in Charlotte, North Carolina. I have an opportunity to place two multi-family properties (one 6-plex, and one 4-plex) on one contract from the same owner. 

I had a few questions. 

1. Is there an obvious benefit placing two properties on one contract?

2. What is the process in doing that? Which contract do I use? Do I make my own or is there a good commercial contract for NC? 

3. What are some drawbacks that aren't so obvious with placing two properties on the same contract?

4. Suggestions, recommendations, or experiences are very welcome. 

Thank you!!
