Urgent Help for James' Family and Pets

My name is James, and in June of 2024, I decided to buy property in Tennessee for myself and my family after the passing of my mother. On November 29, 2024, while living on my land in the middle of building my home, I was greeted by a sheriff's deputy and a husband and wife who had paperwork of ownership. I tried to get in touch with the person we paid and received papers from, but once I started asking questions, I was immediately blocked. Now, my family, myself, 6 dogs, and 1 cat are living in my truck.

To make matters worse, we have my wife's cousin who suffers from MS, my wife has lupus and psoriatic arthritis, and I suffer from congestive heart failure and am unable to work due to a swollen eye preventing me from seeing, with no medical insurance. We have found a place to rent but need first, last, and security deposit to move in. My wife's income is paying for our gas to stay warm at night and back and forth to work. We are in serious need to get help. We have been to all organizations, but there is either no funding or a 3-4 year waiting period. After speaking with family, they told us to create a GoFundMe to get us off the streets.
