They always counter offer.

So, I watched a Bigger Pockets video with Chris Heeren where he mentioned submitting a 30% below listing price offer with a walk-through contingency in it with the hopes that the seller would then counter offer and give you a two to three day period to check out the house.

OR I can be in the process of doing walk throughs, making offers/counter offers and everything is OK as long as I close in 180 days?

After this discovery I made an unreasonably low counter offer to the agreed on price to get out of the deal because I really didn’t care to have the work done and the seller accepted so I got a great bargain!

They start low - you counter offer - and the process goes back and forth until both parties agree.

NEVER counter offer because I only give my Best Price the first time.

If there is one change made, technically that constitutes a counter offer and then must be accepted by the other party.  

I did get an estimate of $100,000 for the repairs which is where my counter offer came from but I think it’ll be closer to $65,000.

I'm a follow-up buyer and keep revisiting my offer and counter offers until it's sold or they tell me to go away.

Expecting to be laughed at and given a counter offer closer to "interest-only payments and 8% at least", I was very surprised when he accepted the terms.
