It's not that it isn't allowed. It largely depends on how the buyer is paying for the home. If it is a cash deal it doesn't matter what kind of condition the home is in. Most of the time the property condition can get in the way if the buyer is securing an FHA mortgage for example where there are certain guidelines that have to be followed in regards to the condition of the home. Sometimes depending on the bank that you are dealing with they may opt to fix the furnace or anything else that needs to be done to make it so the home is "mortgageable", these repairs are also known as "lender required repairs".
