Equitable interest or equitable conversions, however, you choose to express yourself or words should produce some clarity for the seller.   

I literally just finished writing a post to another new BPer looking at turnkey, so instead of eating up your thread with my own wall of text, here's a link to it:https://www.biggerpockets.com/forums/48/topics/399...The gist is this: focus on finding a provider your can trust, weed out the bad apples with plenty of specific questions and high expectations about response time, clarity, and data.Hope some of that is helpful.

For clarity this is my version (so far) of the "rules of thumb".

Having a conversation with a lender will help give you an understanding of your financial picture and help bring some clarity to how flexible you can be with purchase 1 to set yourself up for purchase 2.Happy to assist in anyway possible!

It is very wise of you to be researching your market before diving in head first without clarity.
