You can close in a LLC, but unless the LLC has a solid credit history, a D&B number, etc you will have to personally guarantee the loan. Most lenders want to see a financial package from anyone that has at least 10% interest in the LLC or entity buying the property.
I suggest a solid partner. In the end, looks like you are getting this for 90K. I have some ideas on this, but would need a few more details to see if it might work.
If you are willing to share, drop me a line and I can attempt to assist.
