One of the bids got really close to getting accepted because we got a counter offer. 

My grandmother intends for this rental to benefit my dad as income and she wants to get it out of her name and into a trust to benefit him and his family (my me and my brother) now that they are coming at her with all of these repairs and expenses, she's getting upset and wants to sell the house and let them make a counter offer if someone makes an offer.

The counteroffer came back at $5000 less then asking so we just ignored it and moved on to the next property.About 2 weeks later we still did not have a place under contract to move to, and the closing on our house was coming fast, when the realtor from the duplex called our realtor and asked if we were still looking for a place.

If the other realtor is telling you this that may want to make you say hmmmmmmmmm again They are not suppose to tell you what the other offers are.I agree with all of the answers in the previous post but do not let them make you and your client wait too long or counter offer at something ridiculous.

The seller's attorney wrote back changing some languaages in the contract, but specifically indicated that the contract will NOT be assigned and that my LLC must close on the property.Would this constitute a counter-offer?

Prepare a counteroffer to include new asking price and recent comps that justify your pricing position.

Find recently sold properties similar to the one you are evaluating, determine the average cap rate and use it as a point of reference in your counteroffer.

He has put down a deposit/offer on a parcel of land and now excepted the counter offer.

However they are godawful expensive, $200 for a pack of twenty residential purchase agreement forms, and so many different types of forms might be needed, such as counteroffer forms, contingency release forms, ect.

I proposed 6% for a year, they counter offered 3% for 3 years in case I wanted to rent it for a while.
