I'm interpreting the question as most likely something a neighbour, municipality or other entity has already planted near the bungalow so I'm not sure Jetlou can choose something else. My initial, badly worded, comment meant that if it's 24 feet away it's not the major problem that one of the bigger willows would be, which still isn't to say that it's necessarily a good placement, just not as critical. If it is 24 feet from the bungalow, and the root system is also 24', i.e. 12' in radius for example, the roots are still 12' from the building, assuming nothing else between is vulnerable like a septic system. It sounds to me as though the party wall is someone else's?
Do we know which "corkscrew willow" it is? I assumed 'Tortuosa' because that's the one usually referred to as corkscrew willow, but there are other cultivars:
