New to multi family passive investing

[Mike Gehard]

Hello all,

I'm looking into my first multi family passive investment and trying to dot all of the i's and cross all of the t's before signing on the dotted line to protect everyone involved.

How deeply do I need to dig into the sponsor, deal and location? I've read that the sponsors are the most important one to research. 

What kind of information do people look for when choosing a sponsor to go with?

How important is seeing the sponsor's past performance on deals? Is the number of doors under management enough? Is past performance of the property management company enough?

The deeper I dig the more I realize this is a relationship/trust situation and sometimes that doesn't show up in the numbers.

Thanks in advance,

Mike
