If your wife also owns this rental property, then no, you cannot pay her to do this work.
If you owned this property separately and held it in a separate entity such as an LLC, you could pay her to manage this property but it's not a good idea. Paying her would only move this income from Schedule E to Wages and Income. You'd also have to pay FICA taxes or Self Employment Taxes on these amounts. It is not advantageous for you to do this.
