It is planned to gross 180k this year and if I were to be owner/operator the business could net 100k a year.

Have you documented in your operating agreement anything about that or about how you conduct your money flow (lending)?  

So know the rules where you operate). 

are you happy with the new LLC that took over the operations?

This would then kill your ability to operate as an REI on that homesite.  

Kastle’s Remote Video Guarding enables this by employing AI-enabled video surveillance to trigger live response from a remote Video Operations Center, proactively supporting onsite staff as needed to ward off threats with faster response than guards at less expense.You might be surprised where trouble pops up.

Right now even junk bonds are only paying 4% on average, so where is the seller going to get better yield elsewhere on a fixed income instrument that is collateralized by an asset they know and understand with an operator (you) that they know, like and trust?

Narrow it down to the operation side versus the finance side.  

With a multifamily property there’s almost always someone in one of the units operating like a built in safety net minimizing your losses from non-payment or times of vacancies (remodels/repairs, broken leases, etc..) in one of the units.One more reason to invest over buying is as the equity grows. 

and as such the more return / risk the more the investor needs to be hands on .. that's what I see in the industry. greatest returns are by owner operators who do it for a living EVERY DAY.
