So your listing is found and filtered correctly, maintain the facts when creating or editing. The transaction type is required: Buy, Rent or Commercial. Without it your listing appears in none of the three Immozone tabs.

Add the property type (flat, house, villa, land, commercial, office, garage), living area or plot area, number of rooms, year built and the features (fitted kitchen, balcony/terrace, cellar, elevator, step-free access, underfloor heating, garden, garage/parking space). The more complete the data, the more precisely a party finds your listing via the filters. For how to create a listing in general, see How do I list a property as a vendor?.
