You can borrow  against a 401k or another property you own for example, but that would a secured loan.

And their prices went up so much that I was able to replace them with an all inclusive system including website (I had built my own previously using Wix) with OR for less.  

If you're local you can probably do fine on your own.

Consultations with a local investor-friendly agent and lender as well as attorney-owned title company would be very beneficial in this case.

This is because there’s a cap on how much someone is willing to pay to rent a home today.For example, even if you own a solid property worth over $600,000, the maximum rent you can charge in my area is $4,000 per month.

How can I strike a deal where they can still receive some income from the property, but I can purchase the home and make my share and eventually (1-2 years away) own the home and eventually get full profit from this 8-unit property.

We’re developers managing our own portfolio and don’t have any outside investors.

I put my money where my mouth is on this.We lend our own hard-earned money to local real estate investors.

This is an example of private lending which is different than the IRA owning real estate and does not trigger UDFI/UBIT tax.
