I got an offer of rep. but still have two partials and 1 full out that I'd rather go with. Should I ask the partial requesters if they want to see the full? How much time should I give if I do that? Would having an offer from another agent help make a favorable decision for the others?
Congratulations!
(A word of caution: it might not be diplomatic to mention that you'd rather go with someone else. While it may be unlikely that the agents in question would find this, it's not impossible.)
Rather than ask the others if they want to upgrade, I'd email them an update with the subject line "offer of rep." If they're interested, they'll move more quickly.
While 1-2 weeks seems standard, I'm not sure if that's enough due to the holidays...maybe request a response by Jan. 11? Whatever date you suggest, you should also make sure that's okay with the agent who has already offered.
Getting an offer of rep won't necessarily get more favorable responses, but it will get you faster responses than the average querier.
Congrats again and good luck with the others!
