What can I write off as a wholesaler with or without LLC?

[Michael Merritt]

Hi,

I wholesale in CA and plan to buy and hold property in the midwest soon. I have an LLC registered in CA. What expenses can I write off when wholesaling?

Some of the costs in mind: marketing, travel to sellers/buyers/property inspections, title fees, monthly subscription services to keep the business running. 

What are the tax consequences of not buying things through an LLC? I assume many wholesalers don't do this because then a seller would have to sell to a corporation instead of an individual and thus might lose the deal.
