I used them a few years back to sell a flat in London suitable for FTBs or buy to let - probably at the easy to market/in demand end of the scale, you might have a very different experience selling a family home/unusual building/very rural house/anything harder to sell. I understand ownership of the company has changed hands since as well so things might be different.
Things I liked:
-The cheap price. This was no 1 attraction for me, I did save £££ compared to paying commission at a traditional agents, and overall I feel the cost savings more than cancelled out some of the negatives.
-The online portal - this worked great for me, no hitches, easy access to data such as rightmove views and click throughs, easy to arrange viewings and set your availability on there so buyers can really easily book a viewing at a time that suits them, without having to call or email an office. I think FTBs and landlords have come to expect this level of ease of access, and want to be able to view properties at evenings and weekends which not all agents offer, whereas I didn't object to doing viewings at any time of the day or night pretty much!
-The photographer that came to do pics and floorplan was brilliant, he brought special lights and lenses to get good shots and the final advert looked really high quality, much better than the offering from some of our local traditional agents. I wrote the advert text myself as their suggestion was rubbish but that was a 10 minute job.
-I really didn't mind doing my own viewings, at the time it was no bother to me to be around to do them, and for the most part the potential buyers didn't seem to mind either (although I suppose they wouldn't necessarily have told me if they did), it meant I was on hand to answer any detailed questions the agent wouldn't have known how to answer etc., and without giving the 'hard sell' could present the property really well, talk about our lovely neighbours, how much we liked living there etc.
Things I didn't like were:
-Their valuation service was rubbish, seemed to be purely based on googling local sales prices and 0 local knowledge (really important in London where streets 0.5 miles apart can have drastically different values) or even common sense - e.g. they valued my small-ish 2 bed 1 bath in an normal/oldish building the same as a brand spanking new large 2 bed 2 bath in a super-swanky building with gym and concierge! They also had no useful insight into changing market conditions, e.g. at the time the changes to BTL taxation had just come in but they couldn't tell me anything about how this might affect the market for flats like mine. So if you do it you will need to be confident (get valuations from local agents and do your own research) on a sensible asking price, don't rely on them for this.
-Property took a while longer to sell than I hoped for, plenty of viewings but took a while and a price drop to get a near asking price offer. This probably wasn't their fault per se, but their advice on what to do about it wasn't that helpful - their portal automatically requests feedback from each viewer and they do follow up via phone as well if you ask them to, but TBH you'd get better advice on how to present and market your property from MN!
-Their management of the sale once we did have an offer was a bit lacking - despite in theory having a named point of contact in reality both you and the buyer have to go through to a call centre for any queries, the level of knowledge/service was variable depending on who you were put through to and they weren't terribly proactive about chasing any issues/problems/delays along. Again I didn't really mind because I am familiar with the process and have an excellent solicitor who does all the work, but our nervous/unfamiliar FTB buyers got quite frustrated and upset with eMoov at various points because they wanted and expected more hand-holding from the agent - luckily the sale went through fine but we were at risk of losing them at one point and I had to do more personally to salvage/reassure than I would have done with a better/more motivated agent I think....
So overall I'd recommend an online agent like emoov, providing you are relatively confident yourself in how the process should go (and can challenge/correct anything that's wrong), are happy to be quite hands-on in doing viewings and generally managing the sale yourself and are fairly sure your target market won't find this very objectionable (I know there's a good chunk of MNetters who won't even view a property that's with an online agent, but MN is not universally representative!). So long as you are prepared to risk wasting the fees and/or a delay, you can try putting your property on with an online agent for a few weeks first and see how it goes, then go with a traditional agent later on if you struggle to sell? Although you do lose your initial 'new to market' surge of interest this way....
