And I satisfied $600k this year alone of 6%+ debt or commercial debt that was adjustable, callable and bothering me.  5.25% I would leave alone until I had at least 5 properties.

How long does it take before that helps you pay down some of your debt or create a financial cushion?  

It is difficult to scale without debt or partners with money.

Note that IRS liens attach to all property of the debtor located in the jurisdiction in which they are recorded.

I figure you would want to renegotiate if there was an issue like lots of bad debt or high expenses?

And through crowdfunding/syndications, you can access and diversify into other real estate asset types like debt, or commercial real estate (apartments, self storage, medical facilities, retail, etc.).

You can choose to structure this as a second mortgage, debt or other form of lending with the promised return structured as a debt payment. 

Are you looking for debt or equity?

Like an interest-only bank loan, they pay only the interest until the debt comes due (in this case mostly in 2025, so they have 7 years left to hold bond-investor money).Since the properties are bought outright with these funds, the REIT has a choice to make when payment comes due: issue new bond debt to pay off the old debt, or sell the property which has been collateralized against it.

Also most of the time people seeking owner financing would not qualify for the best rates from a bank if at all due to high debt or other factors, thus the owner would not and should not treat that person the same as someone with great income, no debt, and stellar credit.
