Question about Mobile house

[Sunny Today]

I see some people are selling mobile houses, but I have never seen a mobile house myself? A deion is as follows:

HOUSE ONLY FOR SALE!q Buyer must remove house at their own expense. 'HOUSE ONLY' is for sale.

How can a house be removed and sold?

Thanks in advance.

前段时间不是有这个故事吗......俩老人把房子建在租来的地上,结果地主人要卖地.....他们被迫要搬家什么的...
