Hi all, I lease property to Defence Housing (DHA) and generally have been happy with them. However, each year DHA is required to provide me with a market rental valuation, by an independent valuer, determining the rent as at 31 December. The rent is then adjusted accordingly. If I am dissatisfied with the valuation I have the option to engage my own valuer and present that valuation to DHA. Then the two valuers negotiate to come up with an agreeable figure. Each year when I receive DHA's valuation I make inquiries of local agents as to their opinion. Often DHA's valuation is below market value and I then have to obtain my own valuation. Both valuers are required to do their valuations 'as at 31 December'. However, because DHA has thousands of properties they do their valuations months earlier, eg, September, October. They then issue the valuations after 31 December, in early January. On the other hand my valuations are always more recent, as they are done in January. Sometimes the comparable rents that DHA have used are for properties that were rented out months before their valuations were done, eg, In winter when it may have been a different market. DHA claim that they take this into account, although I've seen no indication that they do. So DHA can be relying on market data that is half a year old, possibly older. Is DHA in breach of contract by providing 'as at 31 December' valuations that were created months before 31 December? Thanks for any opinions.
