How long does a HIP last?
If you are continually marketing your property, and you do not take it off the market, your HIP will last for as long as it takes to sell your property.
If you take your property off the market and then put it back on again, there is no need to refresh the documentation in the HIP providing you relist the property within 12 months of having first marketed the property.
