Mother as my landlord

OH. My (25f) mother (55f) is offering to rent me and my boyfriend (25m) a property she owns and is making payments on. It was originally bought as a vacation home. Her deal is that my rent would be half of the property/utility payments. Her terms state that because she is still paying for half she can sleep at the property during weekends whenever she wants to and have a whole room of the house dedicated as hers. I have an issue with almost being forced to dedicate the time i have off to hosting her for a weekend or two a month. Do i have any leeway? Nothing has been signed and i dont currently reside on the property. This is mostly negotiation navigating. Thanks!
