Condensation itself is a function of the air conditions (temperature and relative humidity ie dew point) and surface temperatures. All surfaces should be comfortably above the dew point to prevent mold. You can use a hygrometer to measure the air, and an infrared thermometer to measure surface temperatures.
Absolutely but one thing about living in rented accommodation - you rarely get to choose the paint.
I agree that a dehumidifier helps but you basically need one in every room. Where I live you can easily take out 10 liters a day from every room during the humid season (which is the maximum capacity of the machine I rented).
