Rent for Reno: what is fair?

[Oksana Yurovsky]

What would be a fair trade between a property owner who wants work done on a home and a contractor who wants a place to live for the duration of the work?

Which factors should be brought into the equation - comparable rentals in the area? Cost of the renovation if one were to hire a contractor? Benefits to homeowner (such as increase in home value/equity?) something else?
