Condo work inconveniencing tenant

[Ganesh Rao]

I have a great tenant in a condo who pays on time and is treating the place well. When in bought the place I was told there would need to be some work done on the unit. That work is extremely noisy and disruptive to the tenant's wife who works nights and sleeps during the day. She is getting no sleep and now the construction company needs access to the inside of the unit for a week or so. Any advice on how to handle this? Is it worth crediting the tenant some portion of the rent for the inconvenience?
