Pan- African housing development financier Shelter Afrique, through its research and policy formulation arm, Centre of Excellence (CoE), has launched a ‘Housing Affordability Calculator’ which will help the Company better address issues of housing affordability in order to improve the viability of affordable housing projects in Africa.
The housing affordability calculator, which was developed in partnership with the Center for Affordable Housing Finance in Africa (CAHF), also seeks to enhance understanding of housing affordability as it pertains to the demand and supply sides in the context of African countries.
“The question of what is affordable is pervasive, but the answer still eludes us. Basically, housing affordability is a function of the purchase price, finance and the cost of living. However, if household affordability is not accurately gauged by public or private sector developers, then there is a serious risk that there will be insufficient effective demand by households to purchase or rent the houses produced,” said Dr Muhammad Gambo, Head of Policy, Research and Partnerships at Shelter Afrique.
“Thus, the housing affordability calculator is vital for Shelter Afrique in evaluating housing project proposals submitted, with respect to whether the units proposed are likely to be affordable to a low-income target market in that location.”
He noted that the viability of affordable housing projects depends upon accurate methods for gauging household (or buyer) affordability and achieving unit costs that meet those affordability constraints.
“This affordability calculator will also assist other stakeholders in the built environment industry to better address issues of housing affordability and to improve the targeting and viability of their affordable housing projects,” Dr Gambo said.
The calculator requires the user to input four data points: household’s monthly income; distance from the city centre; country of residence; and the local currency or US Dollar.
The calculator then applies background data and assumptions based on the prevailing mortgage terms in individual countries, percentage of monthly household income spent on transport based on the distance of the house from the city centre, and percentage of monthly household income spent on transport and housing for each income band.
Empty apartments amid housing shortage
The push for housing development across Africa has led to a boom in new homes, but high construction costs, infrastructure, land and compliance costs mean the majority of such houses are too expensive for those who need them most.
“In most countries in Africa, even the cheapest newly-built house is still not affordable to the majority of the urban population leading to high vacancy rates as we’ve seen in some countries such as Nigeria and Kenya. Developer-built housing typically targets the higher end, and is rarely delivered at scale. But even a USD20 000 house is unaffordable for the majority – and these are only available in limited projects,” Dr Gambo said.
Dr Gambo noted that poor affordability targeting could put pressure on governments to provide further subsidy as in the case of Vision City in Kigali, Rwanda, or in the Kilamba development in Angola” and at the same time impose target price that cannot be feasibly delivered by a developer.
“Our aim is to improve the provision of affordable houses across Africa and we hope that the affordability calculator will help us achieve this goal by making such projects feasible and viable on both the demand and supply sides,” Dr Gambo concluded.
