I have three goals and not sure which to tackle first.

I'll list some of the things below that need fixed, what order would you guys tackle it in?

Why can't one person buy it and be responsible for the loan and create a LLC later to move the property to LLC and tackle the partnership later.I talked to CPA and she is said that's not going to work.

Now we're trying to tackle our mortgage (might pay it off in 4 to 6 years but haven't decided).

You need more experience before tackling that type of project - mainly because you don't know what you don't know. 

You must first assess what area of real estate you truly would like to tackle, then I would say the next step comes more appropriately after that.I would definitely suggest having some sort of income to subsidize all of the costs included with real estate investing.

Sounds like you need to flip and make some money to be able to tackle your upside down property.

Hopefully someone will tackle my dilemma and possibly point me in the right direction.

I do buy and holds, but I tackle it like a flip as I think it's the best option over all as I'm just holding the property for a longer period before releasing it.

Place to find stuff to use to clean and special primer to the structure is JonDon.comThey will have lots of things you can use to tackle this job or to have your contractor do it.
