In order to be 'Aggressive' The seller has to be as committed as the Listing Realtor. How committed to breakfast is the chicken versus the Pig??? This is no market for chickens!!!
Aggressive marketing is pricing 5% ahead of the market and taking multiple offers!!! Keeping the price the same and expecting the Realtor to pay for more media only confirms with more people that the seller is the highest bidder on their own home!!
Feedback is crucial no matter how frank, this has to be passed to the seller asap. 'Let's wait and see' is not an aggressive marketing tactic. Virtual tours are virtual showings. If you home has not more than 10 showings or an offer in a 2 week period you market price is not aggressive enough.
It is better for a seller to have contract offers they can turn down or counter than no offers at all. Throwing money at a bad price is not aggressive!!
