Their silence means no.An Objection is simply a question in their mind that needs to be answered.  

Hey Everyone, Sorry about the prolonged radio silence.

There was a very very long silence and finally he said ok kid you can look at the place and tell me what you have in mind.

I once called a landlord to ask for a reference and then I thought the phone went dead because there was silence.

Meanwhile the other people could chime in or do a virtual hand raise in a chat window but it was mostly silence from the group.

If a sufficient amount of time has passed and you have no explanation from the seller's broker for the silence you can suggest to that broker that there is a break down in communication and that you do not desire to circumvent his positions but you will go directly to the seller for a direct answer.If that does not get a response go to the seller.

Your letter strategy might work, but I'd put money on receiving nothing but silence.

Most investors struggle in silence by never having a group of like minds to keep them on track.

Hi all,I wanted to say sorry for my radio silence!

Trust me though - don't mistake silence for disinterest.
