Can I raise my own rent to reduce my SE taxes for my business?  Would I need to be a different type of entity, or can I own the building personally and keep my tax office a sole prop?

Serious question, the building is for sale, I'm the longest standing tenant and they like the idea of selling to me, we're meeting next week to see if the numbers make sense...if the building can pay for itself with the mortgage Id need to finance, it might be a pretty good investment.
