Helping my mom look for a house

Hi all, my mom is planning on moving to the same city as me in 3 months or so but she wanted to come and visit end of this month to try and see some properties she can potentially buy here. Honestly I am busy for the whole week she’s here except the weekends due to work… but I want to see if there’s any way I can help her. She’s sent me a few houses on Zillow but I have no clue if I should just contact the agent on there and plan for a weekend showing, etc.? I have never bought a house or have experience with it in general, if anyone has advice please let me know thank you!
