Client has a single rental property. HVAC was replaced for $7,000. He claims that under recent tax changes, entire amount can be expensed this year because HVAC was added to qualifying items for section 179. My understanding is that this applies to a business, and having a single rental is not a business. Am I correct and the entire $7,000 cannot be expensed entirely but must be depreciated, and also a section 179 cannot create a loss?
