I found it on the MLS and it makes me concerned it is too good to be true.

But I feel that is true with a lot of insurance companies.

We were initially looking for a duplex but lenders are requiring 15% down for multifamily (I was surprised this was true for first time home buyers).

Is that true?

So true!

While you did sign the contract, your emails may be enough evidence to prove that there was no true “meeting of minds” and thus the contract is not valid.

No more managing tenants, vacancies, maintenance and the managing the manager (who is a $12-20 dollar employee who's compensation structure us not aligned with your goals) By passing the control of the day to day operations to true experts who are literally partners (direct alignment of compensation and motivations), you can assure the investment is being optimized while you spend your time on what you want which is 1) making more money at your day job, 2) spending time with your family or 3) finding that one off deal that you want to do one your own while pairing with a Limited Partner strategy. 2.

Now all this holds true for NNN, but those are basically bonds and leave you at the whims of the market.

Is that true or I'm mistaken? 

You have all the true financial risk, the flipper is taking a risk on his time.
