The affordable housing team forms an integral part of RPS’s development and valuation function, inputting affordable housing costs and values into the open book financial appraisal to negotiate the percentage of affordable housing. Key innovative features developed by RPS – establishment of an affordable housing price which Registered Social Landlords (RSLs) need to bid in order to trigger the affordable housing requirements; indexed affordable housing incomes for qualifying tenants; and a structure which allows developers themselves to act as the qualifying RSL in order to deliver the development comprehensively, have resulted in the RPS approach being regarded as a model of best practice.
