After that, I got a large dog crate and set it up in the master walk-in closet. 

My background is in Social Work, with a Master's degree.

Are all 4 units metered for gas and electric separately or on master meter? 

Buy a 3/2 (if possible), live in the master, rent out the other 2 rooms to friends.

The master bedroom has to have a way to share the bathroom. 

Adding additional bathrooms (like a master ensuite) can be a game-changer.3.

The rental had ratty furniture, a record player prominently featured in the marketing but it had no speakers, missing basics items in the kitchen, lots of drunks in the concrete hallways that reverberated right into the bedroom at 2am, a strong odor of urine outside, and more.We have super hosts in this forum that have hundreds of 5-star reviews and are masters of the craft, but I look at their rentals and see they don't have any artwork on the walls, decor is basic, they do nothing to make the guest feel welcome, etc. 

They also fully refund the tuition from any of their Master courses.

I redid the master bathroom by removing the tub and putting in a standing shower with white granite looking tile, and a custom glass shower door.
