Flat Fee MLS - Local or National?

[Jack Taylor]

If I decide to go with a flat-fee MLS service, I'd like to be able to control my listing myself through some kind of website login where I can change the pictures, description, etc., all myself. Is this possible with any flat-fee MLS listing? Or do I have to contact the agency who is listing my house every time I want to change the listing?

Another question--it seems like the local MLS flat-fee agencies are requiring me to sign a contract about my listing agreement with them. Since I know nothing about flat-fee services, is this ok? I don't want to end up paying more for the services than just the flat-fee. I can handle lock box, negotiations, etc. I already have a lawyer as well.
