Ok, I have been living in a rental house for 4 years now, the landlord would like me to buy the house, however, I am a little uneasy, the windows are drafty and old, the plumbing sucks but what really bothers me is the mildew, there is mildew in seriously every windowsil, all over my bathroom walls and ceiling, (I have bleached them, pinesoled them, painted them and mildew washed them), however there is mildew in every nook and cranny of this house, is their a fix to get rid of mildew or do I need to cut my losses and move. I have come to the conclusion that this can't be healthy. The mildew has actually started appearing in the middle of the wall in one room. It is disgusting and kind of creepy. Please give me some guidance on what my next step should be.
