Everyone is having trouble with MLS offers. Not just you.
In fact in some places even offers at full price are getting out bid by thousands, 96% is an average for retail sales – look it up.
Sign of the times, competition is up and housing stock is clearly low. In fact the money is moving as the stock market run up has provided plenty of funds for those invested even 2 years back.
You’re clearly out of touch - lowball offers are good for no-one and your agent will likely get tired of you. The seller’s agent likely has a personal relationship with the seller and has a fiduciary responsibility – don’t matter if YOU think that’s all its worth (After your profit from it). How’s your inspection/construction experience? Is your work crew ready to go to work when the offer is accepted and did they evaluate the numbers correctly? Do you even have one or was your next step the get an inspection? Offering 70% of list on 2 offers with a random agent and no organization to back you while hoping to profit heavily from someone else’s property – sounds like you haven’t a clue. As mentioned, you definitely are going to get more rejected offers and at some point you will get an accepted one – then watch out.
