If I purchased a used golf cart to be used at my rental property by renters, can I report that as an asset?

Generally vehicles have a class life of 5 years .That is in the consideration used 100% business use.

Enter as an asset and depreciate 5 years.

However take it to the links and personal use % must be considered.That means you decrease the asset value by the % of personal use and depreciation only the % that you use for business.
