Marketing softwares, tactics, text blasting, dealers, etc… thanks!!

I'm an investor with 20+ units with many tactics for making the deal work. 

However, the best use would be as a scare tactic to get them to pay.

Some sellers will try to use sales "tactics".

I'm curious to see if others approach this tactic and how.  

Plus your website must be equipped to capture those leads with some creative marketing tactic.

Sadly, there are non-Jedi appraisers who may succumb to such tactics. 

My normal tactic us to take off the market, control the asset, determine status of title, and do what is necessary to clean up title and gain possession. 

@Jennifer H.A middle of the road tactic we frequently employ with our student tenants, if they drop the ball at the beginning of our relationship, is to strictly enforce the late fee - even on the first offence - but, once the late fee is paid, we tell the tenant if there are no further issues throughout the remainder of the lease we will either apply the late fee to their rent at renewal or refund it along with their security deposit.This keeps the relationship with those who honestly made a mistake and, for those who make such conduct a habit, it is - to borrow from @Jeff Rabinowitz - a drop in the liquid fund ;-)

I am guessing you are trying justify a lower price, but arguing with the seller over whatbhe paid who sets the price may not be a good tactic.
