iBuyer: An iBuyer is a company that uses technology to make an offer on your home instantly. Models vary, but the basic idea is that the company estimates the value of your home and typically makes a discounted, non-negotiable offer. If you accept, they own, market, and resell the home themselves. Depending on the service you choose, the benefit is the certainty of an all-cash offer and more control over when you move.
