Overlooking Minor Repairs: Small issues like broken window locks, missing handrails, or leaky faucets can lead to inspection failures.Incomplete Documentation: Always have the necessary permits and contractor receipts for renovations and repairs.Neglecting Lead-Based Paint Testing: If your property was built before 1978, it may contain lead paint.

They know the tenant base, median rents of different areas, how much to increase rent each year, ranges of repair costs (ex: tenant calls and says AC isn't working, no hot water, faucet is leaking, the HVAC system goes out).

- 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.  

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.

You should be approving repairs of that expense every time.
