ROI for real estate businesses using cold calling services can vary vastly. This means that it can be difficult to attach a specific number as there are numerous factors. The ROI for cold calling services to sell commercial real estate may be higher than residential real estate. Having said that, typically the campaign success can be measured by comparing the number of leads generated to the number of sales achieved from those leads. Essentially, a good cold calling strategy reduces costs and increases ROI, leading to higher revenue.
