Real Estate Investment Database

"Hello all, I am a very new user to Microsoft Access and I'm not sure if I can do what I want to with it.

I work with a new property investment company and we would like to design a database for all the properties that we look at, to make sure we are not double looking. What I would like to be able to do is have several tables (property description, pricing info, realtors, etc), each record within a table would be related to just one property. There will be a column titled ID# that will be the same on each table. I would then like to be able to pull all the information related to just one property to a query or report. Is this possible and if so how do I do it? Thanks in advance for any help"
