I don’t know the jurisdiction so my comments are general. It shows that you absolutely have to know the law. In TX, an eviction of a homeowner requires eviction of the home, not the resident. It is different elsewhere. In addition, in TX the JP (local court judge) does not necessarily follow the law. You need to know from the local court what they will require in cases like this (in advance, not after you run into problems). Now you definitely need an attorney to sort this out.
If you have an attorney who is not calling you back, that is another problem and you need another attorney. It is often too much trouble for attorneys that do not deal with this kind of problem often to get up to speed on what is required. You need an attorney that specializes in evictions for the landowner.
You will probably have to pay for the move of the home. You are actually in a better position than most because the sheriff said you can move it to the right of way just off the property. You usually have to pay to move it to a protected lot, and have the lot auction it off.
It shows that owning a MHP is not a license to print money and requires knowledge, work, money, and sweat. But it is certainly interesting! Good luck.
