So you buy a house and some land....

I don't know what the law is, but this is what I would do... I'd send him a certified letter, return receipt requested. (Keep a copy of the letter.) The letter would list the items specifically and state that, unless he contacts you and arranges to pick them up by such-and-such a date (deadline), you will dispose of or take ownership of the items at your discretion. If he subsequently fails to act and then sues you, I don't think he would win.

What he said x2

[Hold My Beer]

Under Texas law, he forfeited his posessions upon signing. You do not have to send anything if there is nothing in the original contract.

This ^^^

Nothing in the contract, yours at closing...
