Legal Tax Writeoffs for travel

[Anita Z.]

Hi,

What do i I need to write off travel that is used to look for a property to invest in?

Do I need a business license ?

Can I write off all expenses from the trip, such as hotel, meals and travel costs like gas, or airfare? Is 100% of these costs a write-off?

Also, as a real estate investor, can I write off 100% of the education travel for real estate, such as the Bigger Pockets Cancun conference?
