If you drop back to a lower cost slightly older unit, I might agree but a new or almost new if you quickly sell in the fall is likely going to take bigger depreciation hit and as mentioned if you aren't paying cash, you still need to make payments if you wait for a better price and early on in a loan, most of the payment goes to interest not principal.
The nice thing about owning is if you put a dent in it or other minor wear, you shrug and move on. If it's a rental, you are immediately wondering how much you will get charged for it but it really makes more sense if you plan to keep and use it longer term.
