Use your cash to invest in a different property and increase your cash flow and assets.

Caution unless you buy the asset before you market it..

Credit and Assets would also need to be analyzed for a traditional type of loan. 

Antoine best post I have ever read that you have done.. free and clear assets is where real wealth is gained in real estate. 

Systematize everything from rent collection to record keeping, there are many online softwares that can help you out with this.Hope this was helpful!

Generally a REIT might buy a large portfolio and not want all of the properties to re-balance their asset allocation percentages of a certain tenant type or asset class.

I say buy an asset that will give you a return that covers the student loan.

With that much appreciation, you could use a 1031 strategy for example into an even bigger asset. (5+ units, maybe out of state?).

Sorry to confuse you but, bottom line is, LLCs are not tax saving vehicle, they are for asset protection. 

If this is what you have been looking for and you have talked to the seller and found out his story of retiring from the game, looked at the numbers and it makes sense for your "WHY", then all that is left is to execute on the deal and stay on course with your due diligence on the asset itself.
