@Tatiana R., Where do you buy your materials?  

. , I had a similar issue on a 100 years old house too.in my case i resolved by improving a badly designed/implemented gutter system (all the rain water was just dumping over the walls, soaking into them then getting into the basement) and diverting that water away from the house. 2xprimer + 2x good paint.maybe this is the case here.if you don't want the hassle of getting rid of the existing tenants, vacancy and finding other (hopefully) better suited tenants, maybe first you can just paint the place inside and outside and resolve any safety issues (rails). what did you repair to the place?

Thanks Okeoma...I have a good mentor and I am following the systems.
