Currently I make 50k+ a year (bonuses from closing contracts in time, which is also my responsibility, dictates how much more I will get on top of my base salary).

For more details, read this post: https://www.biggerpockets.com/forums/51/topics/1075919-five-common-myths-of-cost-segregation-and-100-bonus-depreciation4.

I received a boxed dinner (turkey sandwich), a 212-page softcover book "Flipping Your Way to Real Estate Profits" by Scott and Amie Yancey, and two free audio CDs: "Flipping Your Way to Real Estate Profits" and a "Bonus Disk" : with two sections: (i) 2 Crazy Secrets and (ii) Scott and Amie Yancey-Commonly Asked Questions & Answers."

The study identifies with forensic engineering detail the immediate Bonus Depreciation 5, 7 and 15-year personal property class lives qualifying portions of a building that are normally buried in 27.5 year residential or 39 year commercial categories.The Cost Segregation Study was performed on the Asset Depreciation Range (ADR) and is based on a 40% tax bracket for State and Federal Taxes.

You could likely enter into a fund that offers bonus depreciation in year 1 to their investors.

I was making $30k per year (plus some small bonuses) and had about $9k in the bank when I bought my first house.

Out of the qualifying assets you'd be able to pick if you want to do 100% bonus depreciation, 50% bonus depreciation or just use the regular 5 year or 15 year schedules.

Is this affected by taking bonus depreciation? 

You pass the exam @ Big 4 and it's a $5k bonus right? 

Use the Big 4 bonus and house hack for the next two years.
