The physical deterioration and economic devalorization of inner-city neighborhoods is a strictly logical, “rational” outcome of the operation of the land and housing markets. What follows is a rather schematic attempt to explain the historic decline of inner-city neighborhoods in terms of their institutions, actors, and economic forces involved. We might think of this explanation as a production-side corrective to traditional “filtering” theory. … It is assumed from the start that the neighborhoods concerned are relatively homogeneous as regards the age and quality of housing, and, indeed, this tends to be the case with areas experiencing redevelopment.
When a neighborhood is newly built the price of housing reflects the value of the structure and improvements put in place plus the enhanced ground rent captured by the landowner. But eventually sustained devalorization of neighborhood housing can take hold. This has three sources: advances in the productiveness of labor (allowing a similar structure to be produced at a lower value than was previously possible); style obsolescence; and physical wear and tear.
Clearly, property owners in many neighborhoods succeed in making major repairs and maintaining or even enhancing the value of an area’s housing. These areas remain stable. Equally clearly, there are areas of owner-occupied housing which experience the first stage of devalorization. Homeowners, aware of imminent decline unless repairs are made, may sell out and seek newer homes where their investment will be safer. At this point, after a first or subsequent cycle of use, there is a tendency for the neighborhood to convert toward a higher level of rental tenancy unless repairs are made. And since landlords use buildings for different purposes than owner-occupiers, a different pattern of maintenance will ensue. Owner-occupiers in the housing market are simultaneously both consumers and investors; as investors, their primary return comes as the increment of sale price over purchase price. The landlord, on the other hand, receives his or her return mainly in the form of house rent, and under certain conditions may have a lesser incentive for carrying out repairs so long as he or she can still command rent. Since the transition from owner-occupancy to tenancy is generally associated with a declining market, some degree of under-maintenance could be expected. With sustained under-maintenance in a neighborhood however, it may become difficult for landlords to sell their properties, particularly since the larger financial institutions will now be less forthcoming with mortgage funds; sales become fewer and more expensive to the landlord. Thus, there is even less incentive to invest in the area beyond what is necessary to retain the present revenue flow. This pattern of decline is likely to be reversed only if a shortage of higher-quality accommodations occurs, allowing rents to be raised and making improved maintenance worthwhile. Otherwise, the area is likely to experience a net outflow of capital, which will be small at first since landlords still have substantial investments to protect. Under these conditions it becomes very difficult for the individual landlord or owner to struggle against the economic declining which they have helped to induce. House values are falling and the levels of capitalized ground rent for the area are dropping below the potential ground rent (see Figure 3.2). The individual who did not under-maintain his property would be forced to charge higher than average rent for the area with little hope of attracting tenants earning higher than average income which would capitalize the full ground rent.
Figure 3.2 The devalorization cycle and the evolution of the rent gap.
Real estate agents exploit racist sentiments in white neighborhoods that are experiencing declining sale prices; they buy houses relatively cheaply, and then resell at a considerable markup to African-American, Latino or other “minority” families, many of whom may be struggling to own their first home. [P]roperty values are usually declining before blockbusting takes place and do not begin declining simply as a result of racial changes in ownership. Once blockbusting has taken place, however, further decline in house values is likely, not just because of the racism of the housing market but also because of the inflated prices at which houses were sold and the consequent lack of resources for maintenance and mortgage payment suffered by incoming families.
Under-maintenance gives way to more active disinvestment as capital depreciates further and the landlord’s stake diminishes: house value and capitalized ground rent fall, producing further decreases in sale price. Disinvestment by landlords is accompanied by an equally “rational” disinvestment by financial institutions, which cease supplying mortgage money to the area. … In addition to mortgage redlining, there is also redlining on the part of homeowner insurance companies, which further induces economic disinvestment. What loans do occur at this stage allow properties to change hands but do little to encourage reinvestment in maintenance so the process of decline can simply be lubricated. Vandalism, sub-dividing of apartments, and refusal to make any repairs soon follow.
When landlords can no longer collect enough house rent to cover the necessary costs (utilities and taxes), building are abandoned. This is a neighborhood-scale phenomenon: the abandonments of isolated properties in otherwise stable areas is rare. Much abandoned housing is structurally sound, which seems paradoxical. But then buildings are abandoned not because they are unusable, but because they cannot be used profitably At this stage of declining, there is a certain incentive for landlords to destroy their own property through arson and collect the substantial insurance payment.
Gentrification is generally preceded by such a cycle, although the process need not occur fully for gentrification to ensue. … The objective mechanism underlying filtering is the depreciation and devalorization of capital invested in residential inner-city neighborhoods. This devalorization produces the objective economic conditions that make capital revaluation (gentrification) a rational market response. Of fundamental importance here is what I call the rent gap.
The rent gap is the disparity between the potential ground rent level and the actual ground rent capitalized under the present land use. As filtering and neighborhood decline proceed, the rent gap widens. Gentrification occurs when the gap is sufficiently wide that developers can purchase structures cheaply, can pay the builder’s costs and profit for rehabilitation, can pay interest on mortgage and construction loans, and can then sell the end product for a sale price that leaves a satisfactory return for the developer.
The process is initiated not by the exercise of individual consumer preferences, but by some form of collective social action at the neighborhood level. The state, for example, initiated much of the early gentrification in the US as a continuation of urban renewal projects, and though it plays a lesser role today, state subsidies and sponsorship of gentrification remain important. More commonly today, with private-market gentrification, one or more financial institutions will reverse a long-standing redlining policy and actively target a neighborhood as a potential market for construction loans and mortgages. All the consumer preference in the world will amount to naught unless this long-absent source of funding reappears; mortgage capital, in some form or another, is a prerequisite.
Three kinds of developers typically operate in recycling neighborhoods: (a) professional developers who purchase property, redevelop it, and resell for profit: (b) occupier developers who buy and redevelop property and inhabit it after completion; and (c) landlord developers who rent to tenants after rehabilitation. … Professional and landlord developers are important … but occupier developers are more active in rehabilitation than they are in any other sector of housing construction. Since the land has already been developed and an intricate pattern of property rights laid down, it is not always easy for the professional developer to assemble sufficient land and properties to make involvement worthwhile. The fragmented structure of property ownership has made the occupier developer, who is generally an inefficient operator in the construction industry, into a plausible vehicle for remaking devalorized neighborhoods.
Gentrification is a structural product of the land and housing markets. Capital flows where the rate of return is highest, and the movement of capital to the suburbs, along with the continual devalorization of inner-city capital, eventually produces the rent gap. When this gap grows sufficiently large, rehabilitation (or, for that matter, redevelopment) can begin to challenge the rates of return available elsewhere, and capital flows back in. Gentrification is a back-to-the-city movement all right, but a back-to-the-city movement by capital rather than people.

House Value
It will be necessary to separate the value of a house from its price. Only in the marketplace is value translated into price. And although the price of a house reflects its value, the two cannot be mechanically be equated since price (unlike value) is also directly affected by supply and demand conditions. Thus value considerations set the level about which the price fluctuates. Now with housing the situation is further complicated insofar as individual houses return periodically to the market for resale. The house’s value will also depend, therefore, on its rate of devalorization through use, versus its rate of revalorization through the addition of more value. The latter occurs when further labor is performed for maintenance, replacement, extensions, etc.
Sale Price
A further complication with housing is that the sale price represents not only the value of the house, but an additional component for rent since the land is generally sold along with the structures it accommodates. Here it is preferable to talk of ground rent rather than land value, since the price of land does not reflect a quantity of labor power applied to it, as with the value of commodities proper.
Capitalized Ground Rent
Ground rent is a claim made by landowners on users of their land; it represents a reduction from the surplus value created over and above cost price by producers on the site. Capitalized ground rent is the actual quantity of ground rent that is appropriated by the landowner, given the present land use. Thus, assuming for the moment an equation between price and value, sale price = house value + capitalized ground rent.
Potential Ground Rent
Under its present use, a site or neighborhood is able to capitalize a certain quantity of ground rent. For reasons of location, usually, such an area may be able to capitalize higher quantities of ground rent under a different land use. Potential ground rent is the amount that could be capitalized under the land’s “highest and best use” (in planners’ parlance) — or at least under a higher and better use. This concept is particularly important in explaining gentrification.
