I have searched the home office and rental properties in this forum. We disputed the reasonable size of the home office and the amount of deduction, but we never questioned the if the home office expenses can be deducted against rental income. This is taken for granted, then why in this court case ( https://scholar.google.com/scholar_case ... 7235183703 ), the judge argue in great length on whether home office can be used for rental? It was convoluted reading, and I fail to see what he was arguing? That was 1980, and now there is no doubt that home office can be deducted for rental?
Suppose it is the case, I would like to get an idea what is the percentage of your clients claim home office deduction? And the average dollar amount deducted?
Given that rental is a passive business, the activity should be light. I am wondering what you would tell your clients if they want to claim all sorts of things such as computer, cell phone, internet, desk, etc to "manage" the rental properties?
