Statute of Limitations...?

Well, a manufactured home is a strange item. Is this home mobile? Are you selling it with land? If so, then you're talking about a real property sale, and whole bunches of other rules apply. If not, you may be talking about a personal property sale.

And your question is that they received a bill of sale but did not take possession? Did you receive your money? If so, it's theirs, and any attempt to resell would violate their rights in the property.

You could contact them and demand removal (I'm assuming that this thing is taking up space) and/or state that failure to remove will result in a rent charge of ____ per month (whether or not you could actuall collect on that threat is another issue). Or you can file an "ejection" action, which would result in the sheriff removing the property at the homeowner's expense.

If not, I think you would need to provide notice that you intend to rescind the contract for their material breach (they refused to pay in a timely manner) and give them an opportunity to "cure" (i.e. follow through with the contract). This seems like a large sale worth a lot of money, so it would be worth contacting an attorney -- a nice nasty letter from a local Alabama attorney might spur these people into action. You might also have a cause of action for any dimunition in value or lower price if you have to sell it again.

(statute of limitations isn't the appropriate term, btw... that applies to the termination of different tort or contract actions because someone did not file within a certain amount of time after the harm).

You sold it to them & they paid for it. It is not yours to resell. Contact the buyer. Give them a time frame by which they need to have it picked up or you will not be responsible for it. Don't know if it is on wheels, but have it towed.

Its not yours to sell
