They wonder why the property doesn’t rent quickly and can’t command top market rent when the kitchen and baths are dated, and the property overall vibe/aesthetic is lacking luster. 

@Carl Rowles we screen all tenants exactly the same, but know several of our local competitors cut corners to attract more S8 applicants - waiving application fees, security deposits, etc.You can try to weed out applicants that have poor "house maintenance" skills by doing surprise zoom calls and asking them to show you their kitchen, bathroom and another room.

Let them know you’re interested in learning and getting experience and that you have some transferable skills.

Lastly when I was newer in the business I was a Land ONLY specialist I sold smaller to larger Ranch style land and depending on where it was and how difficult it was to show standard fee's in those  days was 10% and on some of my deals that were 40 miles of dirt road back into Mendocino National Forest and took someone with my unique skills with maps and compass's to even find the land I charged 20 to 30% commish on those.

How many times do you need to repeat a skill to be considered a master of the art?

Use the skills you learned to find deals for others to find deals for yourself.3.

If you're interested in learning tactile skills like the building trades then doing is probably the best route.

What are some skills you have that you could help hosts with?

You are very skilled at assumption, and proficient in being WRONG. 

They can sharpen skills you already have, or expose you to things you've never even thought of.
