Stone Basement Leaking - how to remedy

[Jennifer Buchholz]

Hi All, I live in CT which = basements.  I am looking at buying a house built in 1920 as a rental- it will cash flow well - it has a stone basement and it is damp - no big puddles or running water, but the walls are oozing a bit.  We are working on getting someone out to the house to take a look at it but in the meantime, wondered if anyone has experience with this.  How to remedy?  Do the remedies actually work or will there always be an issue with dampness? Cost etc.  Thanks,
