But let’s clear up some assumptions.

I was looking into the same product but they are around 7.5% with a .5 point fee as of a couple weeks ago Ok, do some case studies using some reasonable assumptions.

Plus, Somehow the assumption is that an RE investor will pound the pavement, put in hours of research and then purchase RE vs the same investor will comfortable put their money in an index fund as opposed to doing the same level of legwork to pick the right stocks.

New property to invest using $400k as down payment, loan of $900k -$1.3mil buy- assumptions.  20 units at $700 unit average rent or $168k minus debt of $50k debt and $60k expenses = $58k cash flow.  

If you take the interest deduction on your primary home the IRS will assume you live there and the fact that you didn't report it as an investment property, another assumed assumption they will make.

I think there was an assumption that I was marketing myself when I was giving him advice. 

However, there is typically a 5-10% management fee assumption for 5+ units.

Does this assumption include renovating units as the tenants turnover?

I thought about it, but decided the money I'd be putting into the panels, even if financed, would be better spent acquiring another property.Solar panels have even caused some issues at closing with contract assumptions and terms etc.

You are correct in your assumptions.
