General Use Items for Rental Property on Taxes/Accounting

[John K.]

It's my understanding that every asset needs to be assigned to a property, we have 7 rental properties, and buy things like a snowblower that we use at two multi-family properties.  Do we split the depreciation and asset between these two properties?  Or should it be assigned to a single one (for accounting and tax purposes).  I can easily do it in quickbooks, but how does it work when tax season comes?
