1031Exchange and investing in MultiFamily as a passive investor

[Sree Vad]

I have a Condo, which I am planning to sell and do a 1031 Exchange for investing in MultiFamily as a passive investor. Thinking to invest around 150k in 5 or 6 investments of 25k thru Crowdfunding or via syndicators in Multi family investments.

If anyone can suggest  the modu operandi, what , how, how to choose intermediaries to use. Any DO's & Donts

What happens if there is any residual proceeds which are un-invested or if I invest more than the sale proceeds. Is there any limitations on investing in Apartments / offices/ hospitality/ senior housing/student housing .

Or is it a hassle.
