You haven't initialized either _RentingApplicationModel nor _PropertyRentingPriceModel. The easiest solution is to simply initialize these properties in your constructor for AccommodationApplicationViewModel:

public AccommodationApplicationViewModel()
{
    _RentingApplicationModel = new PropertyRentingApplication();
    _PropertyRentingPriceModel = new PropertyRentingPrice();
}

Then, you should be fine.
