Communicate !! One of the biggest issues I have come across is the lack of communication between parties involved in a transaction. It is so so important and when there isn't any and can kill a deal . Really nobody wants to tell someone bad news but if its affecting the sale of the home you better believe its necessary to relay the info ASAP!
Or lets say you have No update because someone else isn't communicating then your job is to let the other party know you are having an issue contacting someone or else the chain reaction sucks! Just remember its so much better to communicate as ignoring an issue doesn't fix the problem it makes it 10xs worse an the likely hood that the other person will be patient after being ignored is far less then if you were up front in the first place ....rant over lol
