What if I have multiple apartments?

If you have multiple apartments within the same block, then there is no need to individually list each apartment. 

If apartments are the same (eg. In the same block with the same address, the same amount of bedrooms, beds, bathrooms, etc.) simply just create 1 property listing and put all information corresponding to only one apartment. Then pick the right unit quantity this will be how many identical apartments you have. 

This will then create multiple listings eg: you have 5 identical apartments
