Currently, my residence is a 3/2.5 condo in an 18 unit complex.

You might be able to buy a 2-3br condo though and rent out the other bedroom(s) to school mates and they will cover most (probably not all) the costs of owning and you will have your own place to live.You can do FHA 3.5% loans on condos, but the complex has to be approved for it.  

I believe that partnering brings some complexity.

A Little bit about me, I am an investor in Las Vegas who is looking to make the ultimate leap into multi unit complexs.

And even then, hope your B/C complex doesn't get left in the dust once the new subdivision or apartment block gets built down the road. 4- vacancy and repairs are related to an owners distance.

That's a massive retail complex that Magic Johnson's real estate investment vehicle is partnering to build by the SoCal architecture school downtown.

We just came back from the area, and looked at several small apartment complexes.

If, on the other hand, you have a more pointed (or complex) question, that requires a specific type of answer, by all means, post it.

So I live in a large apartment complex and recently discovered bed bugs on my mattress.

From what you describe in general there is no need for multiple LLC's or too much other complexity.
