Non-essential Request by Tenant

[Kai Hicks]

Good evening BP community,

I have a tenant who has requested a full power washing of the house. My wife and I like her quite a bit, she is a sweet and very polite older lady who keeps the house in immaculate shape. She signed a 3 year lease, which is great as well. One of the reasons we got into real estate was to be the kind of landlords who are not just concerned with collecting rent, but providing people a decent place to live that they also enjoy. My only concern is that if we agree to the power washing (which my PM says will cost $150) this will open a floodgate (sick pun) of other non-essential requests. The wife and I are very new real estate investors and have zero experience with this sort of thing, so I humbly ask BP: what would you do?
