Market evaluation only applies to rental properties, and the type of evaluation depends on each property's occupancy.
Occupied Rental
It is Simple, if your rental property is currently occupied, running comparables will reveal if the rent is above or below market. In this case if necessary I will recommend changes upon current lease expiration.
Vacant Rental
If the rental property is vacant, using the comparables along with strategic Property Conditioning and Budgeting will ensure your property is coveted above all comps while still being competitive.
