like the building that you can only depreciate 75% of its depreciable basis that would also apply to the appliances as well. but you could expense 75% of their cost in the year acquired. if the tenants will be using your personal property here's what the IRS rules say:
when you convert personal use property to business use (rental would be business use), the value assigned to the property for depreciation purposes is:
The LESSER of...
the adjusted basis of the property, or
its fair market value
...on the date of conversion.
The next question you may have is...
What is the adjusted basis of the property?
The adjusted basis of the property you purchased for personal use is generally what you originally paid for the property on the date of purchase. For example, if you bought a computer for personal use two years ago for $950, the adjusted basis of the computer is $950, your original cost.
Fair market value:
Generally, except for real estate, which may increase in value, things like computers, printers, and furniture will generally decline in value over time. Therefore, the fair market value of such items will generally be lower than their adjusted basis (your original cost) on the date of conversion.
