A real estate success program seems like a high level sales ploy to get you to buy a more specific programLet me save you $1000 and tell you like any business it comes down to following a set of procedures, due diligence and the effort to stick with it as it doesn’t happen overnight and you should constantly be learning and networking

- maintenance and repairs (50/month?)

Quote from @Justin Brin:  I forgot to mention that the arbitrage renter is a very experience host with good reviews for many years and with a team in place.So if that arbitrager would pay me 25% over what I make with it as a STR, covers all repairs and maintenance, then maybe. 

I will definitely ask what we can repair, replace and/ or improve as I usually do.

We always tested people out on small projects first such as doing a gut of a bathroom, 2 day repair jobs, etc. 

If a landlord needs to enter a property for an inspection or repair, a two-day notice is required.

Bought an auto repair shop for 30% of value because of environmental problem.  

You should be approving repairs of that expense every time.

If you feel you need to do an inspection to know around how much cost it will take to rehab, then I would grab a contractor friend for a rough est, and tell your buyer the APPROX repairs needed.

Regarding used mobile homes, you'd have to inspect them to see what issues and/or repairs are needed.
