Once I submit a property and it is of interest to you how long on average does it take for you to close a transactionn

You cannot begin to count the days to closing until the property is in escrow.
The first thing we do is contact the owner to see if they want to sell. 
If you already contacted them, then all we have to do is negotiate a price. If the price is agreeable, then we go into contract and put the property in escrow. Generally, escrow will take about 30 days.

So the answer to your question as to when you get paid is, once you see the submission escrow light on your profile you can look at the date and expect to get paid in about 30 days provided escrow closes and on time.
