So again, I'm not passing judgement on the actual program you are investigating... but will tell you that there are few secrets in the real estate / wealth "game".  

I'd be happy to connect and provide more insight into different markets. 

However, if some carrier is providing this type of coverage, then they better have very strict limitations on the coverage so claims don't get out of hand, or they probably won't be in business very long.

There are several deals floating around but the one I can give rough details as an example is a commercial builidng where 20% is being put down on a 2.5 million dollar asset between 3 TIC equity/capital investors that are each providing roughly a third of the equity.

It’s definitely not a get rich quick game, very much a long term game.

The umbrella provides coverage over the primary policies (provided you have the required Liability limits on those policies) for those vehicles as well. 

(Heck, that alone would probably provide greater returns than that rental.)

Feel free to message me as I'm happy to provide more details. 

. - not a lawyer but I know someone in a similar position who acted as a private money lender (silent partner) on a rehab to generate passive income.You could also look into the many turnkey providers to sites like Realtyshares, Honemestors, etc who will provide you with a K1 for passive income.

I don't know what MN provides.
