To change the price of the place you are renting, you cannot have anyone following the property. If you wish to change the price of the property, then you will have to decline all people following your place. Make sure you really want to change the price of the property.
If you are a flatmate finder or just wishing to let a flat or a house then when you create the property profile you can upload 6 property images.The first property image is the picture of the place displayed when people do a search. You are able to change property pictures after you log into yChatter, by selecting View My Properties and then selecting Edit Property. After this you are able to delete one or all of the property photos.
Everyone has a different experience on yChatter however the more details you provide about the property, the sooner it will be rented. It can take as little as a day to a month to rent out a place. If your place is taking a while to rent then you need to consider if the price is too high, or if you have placed too many restrictions on potential renters, and if your photos of the property are good enough to attract interest.
