Congratulations on the purchase of your investment property.
I'd have to look further at the rules for the deductibility of the course, BP book and subscription however to answer the question on whether or not you can deduct a portion of your expenses, it depends on what those expenses are for. In the example of the inspection I would think you'd be able to deduct the portion relating to the business. You'd have to come up with a reasonable method to carve out the business piece, for example if you bought a duplex and each unit was similar size then 50% may be an appropriate percentage to deduct. But if you bought a four unit building with units of similar size and lived in one of the units then you could argue 75% of the cost is deductible.
I pulled the information below from the IRS website.
"Generally, you cannot deduct personal, living, or family expenses. However, if you have an expense for something that is used partly for business and partly for personal purposes, divide the total cost between the business and personal parts. You can deduct the business part."
