Large real estate agent tax write off???

[Jake Mires]

I need to write off about 40,000 in real estate sales income. Does anyone have any tips for larger write-offs that I can take advantage of before the end of the year? I took the entire cost of a new truck last year and I just have a home office. Looking for some ideas besides your basic food, gas, cellphone bill write offs. I have some ground to cover. Let me know if you have any tips! Thanks in advance
