A single member LLC is a disregarded entity for tax purposes. A distribution from such an LLC would have no tax impact.

There is no income tax concerns here. Your cost basis in the property you purchased became your cost basis in your LLC when you made the contribution (FMV is irrelevant). Now doing the reverse and distributing back out to you personally will mean your cost basis in the real estate will now be what your basis was in the LLC. This concept is known as "carryover basis."
My answer is not intended to be giving legal advice and this topic can be a complex area where the advice of a licensed attorney in your State should be obtained.

I agree with John and Marshall that there is no change in value here. Your cost basis in the property you contributed to your single member LLC is your cost basis when you distribute it back into your personal name from the LLC. Consult with a tax attorney and consider adding another member to your LLC, so that you avoid some of the issues you are currently experiencing. An experienced tax attorney or CPA can guide you in this matter.
