Places that are often or always damp can be hard to maintain completely free of mold. If there's some mold in the shower or elsewhere in the bathroom that seems to reappear, increasing the ventilation (running a fan or opening a window) and cleaning more frequently will usually prevent mold from recurring, or at least keep the mold to a minimum.
The total amount of the previous year’s property taxes is usually included in the listing information. If it’s not, ask the seller for a tax receipt or contact the local assessor’s office. Tax rates can change from year to year, so these figures maybe approximate.
