Automatically download web data to excel sheet

Hi,
I'm not sure if what I want to do has anything to do with macros, but I think it does. I'm a real estate agent. I perform BPO's (sort of like appraisals). I look up in the MLS comparables for a subject house. The MLS is a wbsite containing homes that are sold and for sale. I then transfer the information to my excel sheet. Information such as: beds, baths sq. ft.....etc. I want to know if there is a way the information can transfer to my excel automatically instead of me doing it manually? Thanks in advance for your help.
