Does pulling my credit affect my credit score?

…and how many times do you pull it?

It does have an impact, but a very minimal one compared to the benefit of knowing your financial position and it can be gained back very quickly from good future payments.  Mortgage brokers are not like financing departments at car dealerships.  We pull credit only once and send it through a secure site to the select lender of choice for the application.
