House sitters are by their very nature flexible and often willing to consider your needs in exchange for the privilege of free accommodation in your home. House sitting candidates will generally expect to be asked to occupy your property for a given period of time and to be present in your home every night. You can also ask your house sitter to look after any number of animals, to maintain your pool, lawns, indoor plants and gardens, to forward any mail and phone messages, to pay utility bills as required (working out their personal share of bills at the end of the assignment), and to carry out any basic maintenance that your home requires (such as unblocking sinks, clearing snow from the driveway or organizing the repair of storm damage).
You may have more specialized and demanding requirements from your house sitter such as the sharing of your property with other people (such as tenants or family members), the showing of the property to potential buyers, the supervision of elderly parents or disabled children, the tending to paying guests in other parts of the property, the provision of onsite security (such as in a car dealership), or carrying out more intensive property maintenance (such as building work, the growing of vegetables or the harvesting of crops). All of these requirements would be beyond the remit of the typical house sitting agreement but a house sitter can generally be found for the most demanding position if you cast around wide enough.
