I need to create a branded App, which Landlords can use. I would like the app to have a user customisable tab for each of their properties. so they can put the name of each property and set reminders for mortgage renewal dates. Dairy system for rents due and an easy way to mark them as paid, a diary for the Gas safety and Electrical safety testing, and a notes section where they can list contact information and notes regarding their tenants.
In addition to the diary system, for each property a costs and income system, showing the income generated by the rent, and a section for the costs charged within that tax year so landlords can see how profitable each individual property is.
