I did a counter offer to buyer to cover the appraisal difference if it comes lower and she agreed and accepted.

Even if you sell it yourself - you will likely have to pay the buyer's agent commission - however, you can specify in your listing - or counter-offer - how much you're will to pay them. 

Just had a counter offer on my first duplex.

Once the signed offer or counter offer was received by the Seller, you were under contract.

Hello BP community,I am currently in escrow on my first home purchase and wanted some opinions before making my counter offer.

However a flat no without counter offer is bad likely means they were not happy with the offer think about that when you go back to them and try to come up with a win win.

Aside from some exterior TLC, new windows, and smaller inspection issues which can be fixed with time and investment I'm somewhat suck in a counter-offer situation based on a foundation issue. 

They ended up counter offering too high and we moved on. 

My  understanding is your parents made a counter offer and they accepted part of it. do you have that in writing?  

This way, you may be able see just how motivated this Seller is.If the Seller "comes-back" with another high "counter-offer", try something like $121,500.00.Keep "working the Seller" until the Seller stops "countering your offers".
