Address help for B2 visitor visa

[Gru79]

Hi,

my parents are planning to go for a B2 visitor visa interview. For their DS160 they need to fill out a residence address in USA. They will be staying with me. The problem is I plan to move to a different apartment when they come here for accommodation, the address of which is not known yet. So my current address will be invalid when they come here. What address should they put in their DS 160?

Thanks.
