Although these number are not static, they will help you understand reasonable limits for your RETS download.
If your attempts at an initial full download are unsuccessful, NTREIS suggest the large download be subdivided into smaller packages using MODIFIED. As a guide, below is a break out of the RES Class showing the number of records by year for the RES Class:

Recently the maximum number of allowed images per listings increased from 10 images per listing to 25 images per listing. Again, it is suggested that large media downloads be subdivided into smaller downloads using MODIFIED in the MEDIA Class.
