I was curious if anyone knows what the typical "going rate" is for a general contractor on a normal single-family residential flip. this will be in Georgia. i've been communicating with one who wants to be paid a weekly rate nearing $1k and also 5% of the project costs on the back end.

I'd suggest slowing down, and forcing yourself to communicate a bit more concisely. 

Make sure to communicate responsibilities you have as Landlord vs.

You can also set up a virtual office, mail forwarding, phone and even have your incoming communications go through an Attorney so you have attorney client privilege. 

A good MLO is going to show themselves to you right away by not leaving you hanging, making sure you don't get the run around, and promptly responding to your communications even if they can't help. 

Well over a month has gone by with no communication on his end after repeated attempts from me to contact him.

And this is why tenant communication is so important.  

I am very concerned about data protection and use separate google account for all the communications.

(One big reason why I am interested, seems to have kept it up well)My agent and I have had intermittent communication with his agent and seems to be showing his own frustration with the buyer because he is so slow to make any decision.

 Hey Mindy,  We communicate similarly with our guest.
