Those are all indicators that the road will be very rocky in the future. I would not proceed without a clear understanding and cooperation on both their parts.

I prefer not too.   Clients have the impression they are interviewing me, I tell them it is a two way street.  I have ended interviews and told them we are not going to be a good fit before, and walk away.   Two clients not on the same page, can be problematic.  Or if the seller wants to list at $X and I know, I show them that is way out of line,  I will not take the listing. I dont have the time to waste.  Spirit

It depends on a lot of factors.

I agree with Cindy Davis .  I have had this happen even on estate sale . Never fun .

Maybe.  It depends on the home, price point and the degree of disagreement.

Under those circumstances?  No.  Advise them of what you said above and let them know you would be happy to help them, once they can both agree on items. They will then need to agree on what you need, in order to sell their home.  It will be a daily uphill battle otherwise.

John Mosier If they don't agree, one or the other will probably not sign the listing. If they should reluctantly sign, it more than likely will be a difficult listing to sell. Might be time to pass and come back when they are more agreeable.

I don't think I would take it given what you are describing John Mosier. If they can't agree on the basics, then you can be sure they will argue all the way through. I once sold a listing with a divorcing couple. It was most unpleasant all the way through.

Some people have the patience and expertise to deal with feuding couples, I would rather not.

Yes,  that is for them to work out.

Probably not. You become a marriage counselor and not a real estate agent!

It depends on who owns the home.  All parties that own a property need to agree or it can't be sold.  As far as motivation goes, I'll take the listing if it is priced right and the terms are fair.

I have never seen a husband and wife ever agree on anything so why should they agree to sell . But in your little scenario it seems a bit more complex than that and I sm not sure this couple is fully commited to make the decision to sell  so I would probably decline working with them.

The reality is if the both do not agree, the property can not be sold.

That means it is not a real listing. Now what troubles do you think you are in when your listing can not be sold....and you knew that from day one?
