i would very strongly recommend that you put the new wiring in for a couple reasons. 1 is obviously most people who are looking at older building wiring is going to be one of the first concerns that are going to pop into their mind so its good to be able to put those concerns to rest. second reason is just more personal. if you are holding the property to rent to people and old faulty wiring caused a fire and someone were to be hurt i think that would weigh very heavy on your conscience. i understand we are all out here to make money but wiring is a major cause of fires and i think we as a community have a responsibility to put people into homes we would happily put our own families in.
