We have a couple of leaseholds from NR. They are, without doubt, the most badly organised of our more than 300 landlords, which include councils, the NHSPS, random offshore lots as well as one man bands. You can’t get hold of people, there seems to be no effective sharing of information between staff, yet they are typically belligerent, usually wrong (but admit it less often than my ex wife) and seem to specialise in putting people in client facing roles who don’t have English as their first language and struggle to communicate effectively (when it suits them).
I have spent more time dealing with NR on one property in particular than another in house portfolio of 75 properties with the same landlord. They’re not even cheap. To put it in perspective, they are harder work than dealing with the Chinese or certain of the Arab nations. At least if the estate ends up with a monolithic private equity outfit then they’ll just outsource the portfolio management to someone who will be less difficult (if more expensive).
