Already stated by @Eric Yu in an excellent way.I just recently turned 30 and I can say with absolute certainty that if my light bulb moment came at 22, I would house-hack without question.

______Bath lights at 60 watts and all the same style bulb in place; if multiple bulbs, 40 watts can be used.

It could be someone you intern for, or just an individual that you have met and attracted into your network.Know this: that person is worth their weight in gold, and can be the primary person that you run things past or ask questions as you move through your day.

I believe these things helped the tenant move faster and with two big weights off his shoulders; no cleanup and good movers. 

Earning the certificate in your mentor's program probably won't hold weight elsewhere.

Based on a video walkthrough, the property needs new paint throughout the house, new carpets in all the 3 rooms, new kitchen countertop, new light fixtures and i plan on resurfacing the popcorn ceiling. 

If you decide to put more cash into it, make sure you don't overspend as sometimes the neighborhood's average price/condition/demographics doesn't look good for a brand new gutted property with marble floors and European light fixtures.

That is when you need to replace carpeting, paint walls, replace lights or plumbing fixtures, replace doors and repair windows, etc. 

Give them your business card with phone number and tell them that if you see anything suspicious call the police and you no matter how late or early.Gray area stuff, the home isn't yours and you could be in hot water if the listing agent or seller find out that you placed a cage over the unit before you close so tread very lightly.
