Investors & landlords

Thank you.  Another contributor, Carl, mentioned the following in another thread:

"Property improvements are expenses you incur that add value to the property. Expenses for this are entered in the Assets/Depreciation section and depreciated over time. Property improvements can be done at any time after your initial purchase of the property. It does not matter if it was your residence or a rental at the time of the improvement. It still adds value to the property."  So wouldn't this be allowed?
