If I send an offer and get no response I will usually send 2 -3 more offers each time lowering the amountYour response that “no response is a response” is only known to you as a response. To me no response doesn’t tell me anything. I don’t know if you received my “lowball” offer or that you didn’t. So I’m wondering whether or not to try to contact you again and make a better offer, or no offer at all. A simple response of “ not interested “ might keep some people from “ pestering “ you. JMO
And some idiots will pay what you’re asking with no questions asked. I’ve been known to do that for something I really wanted.
