office for tax deduction

[Jason Phillips]

hey yall ill try to make this short. I have rental business , a 9 To 5 , and a freelance daycare cleaning job . At my house i own a separate building once used as a business by previous owners. Im using it as a 840 sq/ft storage and garage sale spot. The electric is combined with my house bill .

So my question is should i slap a desk in there and call it a office. How much do i actually have to use it per year for deductions . Is there much of a benefit to having a office ?

thanks in advance for any advice
