Thank you all for the responses!
@Ian Ippolito I really appreciate the detailed, unbiased response. I'm going to check out AlphaFlow since it was mentioned multiple times.
I am by no means experienced yet, but I have spent the last two years learning rental investing and I now own 2 rentals. The problem is, I'm in Denver which is more of an appreciation market. That's perfect for me because at this point, I'm looking to build my wealth, not retire off cashflow. My in-laws are looking for cashflow which is harder to come by here. If I lived in the Midwest, it would be a no brainer... I'd buy her some rentals and manage them for her. Since I'm in a more expensive market, it's a little more complicated.
One option I'm leaning towards is this.... Buy a rental here in Denver where we each put in 50%. I would then give her ALL the cashflow but take all the proceeds upon selling myself (except for the money she put into it). Does that sound reasonable? That will double her COC return (since she's only putting down 50%) and would double my return on appreciation (since I'm putting the other 50%). Opinions? Any pitfalls here? I know the obvious one would be investing with family can be complicated but I feel she really would be easy to work with.
I appreciate all the great feedback! I might respond to some of you personally but rest assured, I won't be putting any of her money into anything I don't fully understand.
