I've had one rookie investor attempt to do a lipstick flip, and they're property might not sell for what they want it for, and so your margins may be thin..

Mortgage underwriting and pricing is complex financial work with very little margin for error (especially nowadays.)

There is less room for error.

You could read 100 books and still not know enough because certain things must be learned through trial and error.

I am a rookie here.

Tell him the 15th was the end date and the error was the automatic payment was not canceled. 

I’m also 99% sure most lawyers have some insurance to cover such situations,  Errors and omissions insurance?

There's no margin for error on timing the turnover, let alone getting a tenant who causes excessive damage or needs to be evicted.    

Tell them there was a banking error, and the funds are being transferred back.

@Bob Stevens“Investor friendly” (insert type of contractor you need) - everytime I hear that I think - they want the cheapest price available.Saw a post recently on here someone complaining that tenant was complaining hvac was not working and they were doing trial and error to fix it.
