I am not looking to take equity out against my house, and my other 2 rental properties are already going through a cash out refinance to pay for renovations of a fixer upper that I am buying.

What are the essential pieces of furniture and amenities I should include to make the unit attractive and functional for college students?

My plan is to sell my current house which will give me around $300,000 and in the next 2 years me and my wife will save another $100,000 which come to the total of cash we have in hand is $400,000.

I will cash buy as I don’t really like their financing and don’t want to deal with currency fluctuations causing my payment to change month to month. 

They didn't have access to BiggerPockets where they could learn how to calculate cash-on-cash, ROI, ROE, or print reports with colorful charts and graphs.Earn money.

If you NEED cash flow to invest in real estate you’re not ready.

Do you have access to the paid version of airdna to find comparable properties that are cash flowing at 500-650 a night? 

With current prices and interest rates, you're not cash flowing with LTRs.

The podcast you mention is referencing (i) Freddie Mac Small Balance Loans ("SBL"), and (ii) Fannie Mae Small Loans, which are essentially government-backed CMBS loans. 

I presume you are trying to "add value" in terms of increasing cash flow, not in terms of increasing the value of the home (for you to later cash out refinance)?
