If you have agreed a new rental amount with the tenant because e.g. the property will now be provided furnished compared with the original listing, this isn't a problem. It's sensible at which every stage in the application you are to have confirmation of the new price in writing with the tenant (e.g. by email) to prevent disputes.
Before the holding deposit has been placed
If this has been agreed before the holding deposit has been placed you can change the rental amount on your listing by heading to the 'Edit' page from your account. You will need to reject any outstanding offers you have on your property first, as increasing the rental amount while you have outstanding offers could be considered encouraging rental bidding, which is prohibited under the Renters’ Rights Act 2025. This will reflect on OpenRent within the hour, and your applicants are able to place the holding deposit on the property and continue as normal through Rent Now.
What if the holding deposit has already been placed? Or you don't want to advertise the lower rent?
Once the holding deposit has been placed, you have the option via the website to adjust the rental amount.
If you are currently on the referencing stage of Rent Now, we have some guidance here.
In general, as long as both parties have agreed the new rent in writing, everything should go ahead without any problems.
