Who we are?

We are a small and passionate start-up filled with dedicated entrepreneurs, chartered surveyors, developers and valuation geeks. We have carried the project through with our own very limited resources for the past 30 months. This involved much tears, laughter, achievements, setbacks, frustrations and extraordinary learnings.

Who is this product targeted at?

This is for any property valuer who is following the IVSC and / or the RICS Red Book. It allows valuers to follow the standards to the letter without needing extensive periods of training for chartered membership, the need to go through the standard books in detail at each assignment and making human errors common with “manual” valuations and adaptations of clumsy word templates. The key advantages of the software are that it allows for valuations to be carried out faster, cheaper, more accurate with fewer human errors and completely to standard than manual template adaptation systems. This is a complete solution that allows a valuer to monitor and carry out the entire valuation and client interaction processes from a single, easy to use platform.

What version of the Red Book / IVSC is this compliant with?

We follow the latest version of the standards at all time. At the moment we are on RedBook, IPMS and IVSC 2020.

Why do we care about the standards, I just want the calculations?

While the calculations form a very crucial part of the property valuation assignment, they are worthless if the assumptions underpinning them are not present and clearly explained to the client. The standards are there to promote transparency and understanding between valuer and client and making sure that all valuers follow the same rule book. We follow the standards to the letter in an effort to provide better valuation reports to clients that are clear and well explained with all underlying assumptions and decision making clear and well explained.

How can you guarantee that the valuations are correct?

We do not guarantee that the estimate of value itself is correct, that part is all down to the skills and expertise of the valuer, we only provide the frameworks to make sure that the valuers follow the applicable standards to the letter. Through the use of the software the valuers will be faced with a series of clear choices on bases of value, approaches, methodology, assumptions etc… All the choices they make will be clearly explained in the valuation report and any significant changes and client communication as well as all additional justifications will be displayed in an automatically generated audit trail.

My country has adopted the IVSC but the market is different and some regulations contradict it, how does the soft handle that?

That’s fine, allowances are made for departures from the standards as long as they are explained and justified properly. The software allows valuers to state any departures or special assumptions that are particular to a market or asset class.

I’m not entirely up to scratch on the standards, are there training and support elements in the software?

Yes, plenty, we have a full complement of training that takes valuers that have good practical “on-the-ground” experience and teaches them the key aspects of the standards. We have also put “tooltips” all over the menus to better inform the choices that valuers have to make. The more valuations a valuer does, the more they will understand and see the value in the standards.

How much does Interval's license cost?

We’re not sure for the moment. All we can say for the moment is that it will be a monthly subscription per user and that the first 1,000 users will receive a 6 months free trial period.
