After speaking with your son whom said you were looking to purchase your current home from a friend, I would recommend that you pay for a appraisal, in which the appraiser actually walks through and measures the home, you also may want to consider a home inspection, that is really not a Land lease area however make sure

Now don`t get cheap on your investment, spend the 3 or 4 hundred, it could save you a bundle.
As the other agents have stated, REALTORs cannot give an appraisal but we are experts giving you a market value for the house. That's what we think the house will sell for in the current market. This price can vary depending upon the time frame that you have to get the house sold. A longer marketing time may yield a higher price for you but that is something that I would be happy to elaborate on further when I know more about your situation. Please feel free to contact me and I would be glad to share my ideas with you.
A REALTOR is not a appraiser, we can not appraise your home. You would need to hire an appraiser.
There are companies out that will buy your home if they can not sell it, however be careful. If you decide to go that way, Get Legal Advice First, Read The Contract they want you to sign. Get legal advice
