I think that if you can sell it yourself you should go for it.
OTOH, it may be that you will not be able to sell without professional representation.
Just so you have the facts:
The NAR did a survey last year:
85% of homeowners who tried to sell on their own eventually listed with a Realtor.
5% sold to someone that they knew
5% sold to someone they did not know
Homes sold by owners without professional representation sold on average 16% less than those sold by Realtors.
So I suggest that you interview three Realtors, run the numbers, when you make the call. If you try it on your own and it doesn't work out, then you've got plan B ready.
I don't think that anybody is trying to "cut down homeowners" here... the question was asked how (from a seller) to post their home here on Trulia...
as rockin' and Jed have pointed out... Trulia only accepts listings from Realtors. We have checked and Postlets will not publish non-realtor listings to Trulia or Zillow.
that's not "cutting anyone down"... that's being helpful and informative, wouldn't you agree?
