Does this seem like my CPA is overly conservative

[Sean Harrison]

I really like my CPA, last year was the first time using her. I feel that she might be a overly conservative and not help me write off as much as i should. Does anyone get to write off traveling and looking for new rentals? If i travel to another state to look at a house, i was told i can only write that off if i actually buy one. Does that seem correct to everyone?
