I've read everywhere that they do not.Can someone explain which one is the correct choice and if any extra taxes are involved if they need to be on the LLC?

You can do a duplex though, which might not be a bad idea.With your credit score, conventional might be a good choice, you only need 5% down for 2-4 units if you live in one. 

The real property investment can be repositioned if it proves disappointing in its original form; it can be refinanced or recapitalized if it has too much or too e pensive debt; inflation over time bales out many bad purchases, and finally the investors knowledge, experience and abilities can be leveraged to turn around a cash flow negative property.I’ll provide an exampleThree years ago we purchased a note from a bank secured by two auto repair facilities with a large amount of excess land.  

That will get you from zero to about 80% knowledge level.1.  

@Jay Hinrichs you live in Oregon, what's your knowledge in this area?

It's where real estate knowledge meets opportunity, empowering you to turn your investing dreams into reality.

Get knowledge, follow experienced people, and leverage wisely.My Take:If you have two houses, excellent credit, and motivation to build wealth, you can learn to manage your money responsibly.Use HELOC, credit cards, and business credit funding to leverage your cash and buy properties faster.

The garden unit tenants stopped paying rent, and I had no choice but to start the eviction process, which is still ongoing.

What’s also interesting is the homes Wavemark was supposed to purchase to my knowledge have not been placed in any park (I know of 3 parks that have had zero infill).

I work full-time; I’m trying but I know there are gaps in my knowledge.
