Couple reasons:1) More limited financing options.2) More limited use and structure for the deals.3) Finally, if you have to inject extra cash into the property for whatever reason (manage an economic downturn or natural disaster, for instance), it's going to be trickier using an SDIRA.Syndications and private lending protect you from much of the property management nuance.

My questions are:1) What is the best corporate structure for our partnership based on the info provided?

She would like to partner with me and flip the home, but her brother just wants his money and be done with it.He has agreed to let me buy him out of his half of the property for $60,000 and he will then quit claim his half to me.How should I or would you, structure the documentation for this deal?

There are many experienced investors on here that will analyze your deal and make sure it is structured correctly.So in summary, the first thing I would do as a real estate investor is EDUCATE MYSELF.And we are happy to help in any way we can.Once again, congratulations and I wish you the best in your real estate investment career, Jason!
