depreciation is the business expense
It would be more likely to be considered an investment !!!
It would however be considered an asset
– whose value to the company should be periodically 'valued'
and when you eventually sold it – that would represent a profit.
You only need to depreciate assets that immediately lose value over time or by virtue of being sold.
eg Furniture, cars, PC's etc.
Real estate doesn't depreciate. Only fixed assets depreciate.
Depreciation is against the capital asset value.
Expenses are expenses, and are treated separately.
