I do agree that an all cash later will buy more real estate a year from now then it will right now.
That said, yes an all cash offer is always given much more consideration then a financed deal. It sounds like you are asking how much of a premium it gives you as a buyer. This is hard to quantify because all sellers are unique. There is not a hard and fast rule. If you want to lowall a 350k home at 290k then write it up and send it in! The worst they can say is no. The best they can say is yes.
While cash is certainly an effective tool, the MOST effective tool to lowballing is time. Lowballing a home that has been on the market a few days or even weeks is generally not effective. Cash helps but may not be the cure all you think it is… Time time and more time is what breaks people.
