I was offered a deal to do a joint venture on one of the houses that needs a little work ($7-10k).

Welcome @Jasmine Patel and congratulations on your decision to venture into real estate investing!

Wishing you all the success on your real estate ventures!

I was a Licensed Mortgage Broker back in 2005-2009  and flipped a few homes when no real skill was needed back then and made good money which I foolishly invested into a joint business venture with my hubby in 2006.  

All the best on your real estate ventures!

You might want to consider a Joint Venture with an experienced note investor, as they can show you the ropes, and you get a note that you split profits on, vs paying for expensive training. 

There are many people willing to Joint Venture on a project that may be willing to partner with you and provide the cash for a percentage of the profit.

RealeFlow or ListSource should have that for you, and the benefit of having that list could also be if you drill down the rabbit hole, you can find the corporation/person who is buying those houses with cash, so you can try to get in touch with them.Congrats on the new venture with your husband.

If I set up a series LLC with my wife do I have to include the equity partners as part of that LLC or can I just have a joint venture agreement set up for each property.  

Good luck on your new venture!
