I have about $500k in equity across my other properties, and thinking about pursuing a master lease into seller financing like Brandon Turner did with his first apartment building.

That's a masterful and amazing thing to be able to do, and most people will never do it because they don't have the knowledge, a contractor they trust, or a dozen other excuses they'll make."

Usually, these types of homes are gated sections within the larger master-planned communities. 

An old vent in the master bedroomImages are attached.I'm not sure if these are things to be worried about, or if they are just minor cosmetic things that could be fixed.

When you find deals cheap, you have more options: you can wholesale for a quick few bucks, fix up and refinance for a rental or rehab and sell to make the bigger kinda quick bucks.Your profile says that you are getting your masters in Business.

I have a bachelors and masters in engineering, but when I decided to start investing and when I got licensed and begin my agent business, I learned everything from books, podcasts, those around me. 

There's such opportunity with these renters I'll have to get creative, maybe a master lease opportunity lol.

Tomorrow I am taking my test to get my Master's electrician license.

Any seasoned agents out there who have mastered fb advertising?

Aka "Master leasing".To be abundantly clear, I have never tried either of these, nor have I run them past legal counsel.
