I own the land and someone else owns the mobilehome that is on a permanent foundation on my land. The property is now in foreclosure for non payment, can the owner remove the mobilehome to his own lot/land if it is on a permanent foundation?

Of course - is there some reason why you would want to stop him? Or by 'can' do you mean able? We don't know if he is able to move it. That depends on countless factors that only a mobile home mover can answer by inspecting it. Then there's all the problems that go with setting it up on another plot of land. There may be many new code requirements regarding water and sewer, etc, where he plans to go.

Or am I reading your question wrong? Does the lender claim that the home goes with the land? Or is this a tax debt?

They just rent space? They have ownership title to the MH?

If they removed the axles and hitches, it may be harder to move it, but it still can be done. But yes, the mobile home is still separate and has its own title.

I tend to disagree. If the house were a "stick-built" structure, the person who built it can't just pick it up an take it away. It's a matter of degree, but appears to be substantially the same thing. If the MH has been made to be a permanent part of the real property, the mortgage holder would be entitled to object if someone tries to take it.
