Can I set my own price $50 house/dog sit per overnight stay?

Yes, of course, you set your own pricing. It may show a suggested price, but you know your local market and the value of services offered. Sometimes newer sitters price towards the lower end of their local market in order to generate interest and build a client base, but $25 is shockingly low, especially if you’re newer and retaining 80% of that$25= $20.
