WordPress and Damage Deposit
You can decide if you'll be taking the damage deposit fee for your WordPress reservations with the option "Exclude from reservation sum" present in your Hostaway listing info.
The option is called "Exclude from reservation sum" and if you choose not to include it, the deposit will not be included in the Total Reservation and you will have to charge that deposit using Pre-Authorisation for Auto Charges.
The option can be found under Listings > Prices & Fees. By default, the checkbox is unselected.
