In my case, I suck at property management and so turnkey has been better for me.I also rehab lots of properties in my area and excel in this sort of thing.

I believe it's an excellent strategy, but it won't work unless you have a desperate person trying to get out of a property, quickly, and they're willing to make the kind of money you need to get it done. 

You should tape that letter enclosed in an envelope with the tenant's name and personal & confidential underneath, which is excellent @Max James .In your jurisdiction change the verbiage to indicate that if they pay you before the 5th the late fee will not apply.

I believe in excellence and professionalism in everything that I do, pertaining to business and life.

@Bryan EXCELLENT!!!!

I provided the client with a letter, the manufacturer's installation instructions, and photographs documenting the situation and they in turn took the matter up with HD.  

You've got some excellent advice all ready.

There are some excellent areas of the country that still do.  

I also figured out how to calculate it in excel if anyone is interested.

It's a great feeling to see someone else begin to excel after you've taught them what you know and they put it into action.
