Investors & landlords

thank you for your input. 

I am not looking for any extra deduction from the use of the rest of the house or yard, I was concerned given the questions that TT asks, that it made the business use of the room a smaller percentage. It asks the questions in two different ways that confused me, one had to do with percentage of income, one other place it reworded it as percentage of time. I use the room for invoicing, supplies, and crating the dogs. 

The majority of time I am in the rest of the house/yard.

If I take the simplified method, I will be losing a lot of the deduction, since I can't use interest and property tax on schedule A. does the simplified method also require the same questions for business use? 

thank you for your help
