In our two month experiment using Assist 2 Sell, we encountered one confusion after another. Our selling price was listed at two different amounts - on the same document - and efforts to have it corrected even after many weeks and many phone calls and many e-mails. Erroneous flyers were left in our sign box, truly horrible pictures taken of the house - we ended up taking our own and subbing them on the website - and more. Every single interaction required two and three follow-ups just to make sure nothing was dropped. Oh, and our house wasn't "officially" on the market until almost a week after we signed the contract. Why? Because the lead agent "forgot" to process the paperwork.
The potential to save money might be present using Assist 2 Sell, but the amount of time it took for us to just get basic information correct and established cost us much, much more than we ever could have saved.
