I would recommend sticking to one strategy at first before you venture into others.

Commonly automation works best on manual, repetitive workflows, especially if you have multiple properties or units that needs to be tracked. 

Im mainly here to build relationships and to partner on STR, LTR, and possibly do some flips - if you have other business ventures Im interested in that as well!

a joint venture agreement would be best 

It's helpful to have economys of scale in any business venture, but in new construction it's even more important because you really need to drive the price down. 

You’re acknowledging their expertise and the role they play in making you feel confident about your investment.Wishing you all the best with this deal and hoping it’s the first of many successful ventures for you!

I have been with them for a year now... my first venture in memphis a duplex.

Joint venturing, paying a larger sum at the end, hiring contractors on credit are some ways I know.

Maybe those two are  correlated.I've done some private money lending , but buying other's notes or something or pursuing this venture is rough.

All the best in your new venture!
