I'd be surprised if the complex doesn't have individually metered units so you may be able to eliminate the utility expenses unless those are for common areas like walk ways, parking lot or laundry.

But if you are looking for 1-4 units residential purchased by an individual then PS is a great place to find a list, skipt trace then cold call or text. 

All the other individuals who have commented on This Thread get that, and I love them for it!

This duplex will most simulate TWO INDIVIDUAL HOUSES.  

I can't tell if you want to buy land from an owner who finances or if you have the funds to buy and then sell the lots with you being the owner who is financing to individual lot purchasers?

If you take the individual investor model, you need to find a Whale.  

we did this a lot pre 07  in that year Oregon WA and then CA made laws that had lots of teeth about dealing with those in foreclosure.. so we just stopped doing it risk was not worth it.I cant see how an individual can do this really..

I would echo this, it is a great REIA and the best place to find local, like-minded individuals and resources. 

Quote from @John Friendas: Hey,My investing partner and I have reached an agreement where he would have the debt under his name and apply for it individually, and I would do the majority of the management (he is out of state and my income is half his).

You would have to go after the one individual for non-payment and you could only remove the other three by going through the legal process like you would for someone on a verbal agreement, which puts you in a he-said, she-said situation.
