# How do I turn an agent’s brochure into a 10-year appraisal?

The tenancy schedule, rents and lease expiries go straight into your own spreadsheet.

Headline result: Passing rent is £157,500. The asking price is £2,150,000. The net initial yield is 6.86%. 2 template errors were found.

## What did the client ask for?

An Investment Director at a Scottish property investment company was keying every brochure into the firm’s appraisal model by hand. While testing the Skill, I found a WAULT formula error and broken #REF! links in the template. They had been sitting in every appraisal.

## What did the check find?

- Unit 1, trade counter, £42,000 a year, 5.00 years to expiry.
- Unit 2, car servicing, £36,500 a year, 2.50 years to expiry.
- Unit 3, parcel depot, £51,000 a year, 8.00 years to expiry.
- Unit 4, building supplies, £28,000 a year, 1.25 years to expiry.
- WAULT is 4.73 years.
- The WAULT formula in SUMMARY!D12 is weighted by floor area, not rent.
- #REF! in CASHFLOW!F22:F24 after a deleted row.
