If the tenant remains in the rental unit after receiving a termination, the landlord can bring an eviction action. Traditionally, a U&O agreement comes into play whenever an initial billing date is changed or delayed by other means. Most of the time, this agreement allows buyers who may have already abandoned their previous belongings to use their new home before officially taking over ownership. This could mean that they rent the property for a few days to the seller or simply move their belongings before. This is the most important advice of all. If you plan to use this type of agreement during your transaction, write it down in writing. Not only that, but make sure you have a professional – that is, either your lawyer or your real estate agent creates the papers.
