Trying to understand on my own was challenge as it required me to understand bit more then i knew, and my llc and situation was bit more complex then i originally thought.Thanks again

This last one can be more complex, because certain types of income can be used and certain types can't. 

I would like to start with just one duplex, but I've been presented with this opportunity to buy a small apartment complex here in South Florida.

It's probably much more complex than you need and a Promissory Note and potentially a mortgage (if they are lending for a particular property rather than to your entity) would suffice.

That the rules are you had to live in it for a year and only 10% of the complex can be rented out.The problem is I have owned this condo for 7 years and been renting it just fine. 44/60 units in this complex are rentals.

However, some people make this work, it just adds a lot more complexity to the equation.

I’m originally from Plano and always looking to get back home with a 20+ units complex!

Storage is not rocket science by any stretch but if you are new to this, it might be advisable to master that before adding to the complexity.

I have an apartment complex in a college town that I picked up late last year.

Here's an idea @David Sweatman:If you have a 100k to invest then your personal residence is probably paid off.If you have good credit, use the good credit to get a HELOC at a great rate.Then use the money from your HELOC (and the 100k) as a down payment for a 20-40 unit apartment complex or commercial building.If you have an IRA with more 50k - you should consider using a self-directed IRA to invest that money in real estate too.
