I suspect they are very good at getting everything done. I have read many good reviews of them, but I stil have a sour taste in my mouth. I made an offer on a contract which I thought was reasonable ($/points and slit MF and closing). My offer was around $10 lower on the points (which they had listed high). I was basically told that it was too low of an offer and that the MF fee is always paid by the buyer. They did say they would present my offer, but made me feel dirty. After a day of not getting any return (and also looking at a very similar contract elsewhere), I called. The person I orginally spoke to was not in and the back up did not have the specifics. I got a call back a few hours later that I had to let go to VM since I was on a work call. THey VM said that the seller did not accept. And that was it.
I made an offer (and was accepted) on the other contract / other company (which has been sitting for over 8 moths) and got more points / lower cost / point and I buyer paid MF and we slit closing.
So, my one and only experience was not good and I did not even consider them for my most recent contract I am working on.
I do think if you are looking for the lowest cost per point and some deal on MF/Closing, TTS is not the place to go.
