1. Be clear about the purpose of your purchase, whether it is a construction site for residents or a warehouse, long-term or short-term use. It is more cost-effective to buy for long-term use, and more cost-effective to rent for short-term use.

2. Shop around. Don't just care about the price when buying, and you won't suffer a loss if you really shop around. The price of the container house varies greatly due to the use of different materials. The quality of the low price is not necessarily good, and the price of good quality must not be low. Searching for container houses on the Internet will show many manufacturers, and you can fully understand the product materials, specifications, service life, and performance.
3. Sign the contract. When the price and product are satisfactory, you must sign the relevant contract and mark the relevant details, such as quality assurance, payment method, Party A and Party B's rights and responsibilities, delivery date, delivery method, exit method, breach of contract, etc., to let your rights and interests guaranteed.
It is generally not illegal to put people in container houses on rural homesteads. At present, there is no relevant law to make corresponding regulations on whether container houses for people living in rural areas are legal. The residential container house is a temporary building that does not occupy land quotas, as long as the homestead you place is legal.
