Detaljhandeln befinner sig i ett skede av förändring som en effekt av de stora digitala framstegen som skett de senaste åren. Rapporter från fastighetsvärlden vittnar om mängder av butiker och kedjor som tvingats till nedskärningar och i extrema fall, konkurs. Förändring innebär både möjligheter och risker och den stora frågan är hur en ska agera för att lyckas minimera riskerna och maximera möjligheterna. Ett segment ur detaljhandeln har inte drabbats i samma omfattning, dagligvaruhandeln vilken innefattar livsmedelsbutiker som generellt fortfarande positiva siffror i den fysiska handeln. Det primära syftet med studien är att hitta den mest lämpliga hyresutformningen i butiksfastigheter, givet de mest förekommande hyresformerna utifrån hyresgästens perspektiv. Ett särskilt fokus har lagt på omsättningstillägg och dess lämplighet men indexerad bashyra undersöks också i fallstudien som jämförelseobjekt. Omsättningshyran och omsättningstillägget sägs ha haft sitt genomslag i Sverige under 1990-talets fastighetskris som en räddning av dåtidens höga vakansgrader. Metoden som används har varit av kvalitativ karaktär, där semistrukturerade intervjuer har genomförts med respondenter som representanter hyresgästens perspektiv med undantag för en respondent. Det korta svaret på vad som ingår i det optimala hyresavtalet bland ICA-handlarna är enstämmigt, en låg hyra. Undersöks saken mer ingående finns andra aspekter som är av stort värde så som en god dialog med fastighetsägare, låga vakansnivåer i centrumet och att fastighetsägaren ser långsiktigt på sitt ägande. ICA-handlarna som har en hyra med omsättningstillägg saknar ett tak på omsättningstillägget för att nå ett optimalt hyresavtal. Studien visar också att utformningen på ett optimalt hyresavtal är subjektiv och ser olika ut från fall till fall. Vägledande i valet av hyresform kan vara att omsättningstillägg endast är aktuellt i fall där en hyresgäst kan dra nytta av omkringliggande butikers kundflöden och centrumledning jobbar aktivt med centrumets utveckling. Finns inte detta så bör hyresgästen yrka på en fast hyressättning. Grundläggande för ett fungerade hyresavtal är att föra en dialog regelbundet med fastighetsägaren och ha en omfattande gränsdragningslista. / Retail is in the middle of a structure change as an effect of the major digital development taking place. The real estate industry reporting of numerous retailers that has been forced into cuts and in extreme cases, bankruptcy. Change means both opportunities and risks where the million dollar question is how to succeed in minimizing the risks and maximizing the opportunities. A segment that hasn´t been affected in the same extent is FMCG (=Fast moving consumer goods) that is still presenting positive figures from sales in the physical store. The purpose of this study is to find the most optimal rental arrangement in retail properties according to tenants, given the most prevalent rental forms. A special focus has been allocated to turnover rents and its suitability, indexed base rent is also analyzed for comparison purpose in the case study. The turnover rent is said to have entered the Swedish real estate market during the crisis of the 1990s as a rescue of the high vacancy rates occurring at the time. The method used has been qualitative, in which semi-structured interviews have been conducted with respondents who represent the tenant's perspective, one respondent represented the property owners perspective. The short answer to what is an optimal rental arrangement is among ICA retailers is unanimous, a low rent. If the matter is analyzed further in detail, there are other aspects of great value to the tenants such as a good dialogue with property owners, low vacancy rates and that the property owner are long-term owners. The ICA retailers who have a lease with a turnover rent are lacking a cap on the turnover rent in order to achieve an optimal rental arrangement. The study also shows that the optimal rent structure is subjective and vary from case to case. Guidelines in the rent negotiation may be that turnover rent is are only preferred in malls and cases where a tenant can benefit from the surrounding stores' footfall and also, when the shopping center management works actively with developing the mall. If these prerequisite are not fulfilled, the tenant should demand a fixed rent. Fundamental in all arrangements is to keep a dialogue regularly with the property owner and have an extensive list including delimitation of responsibility in the lease agreement.

State of Objectives: This paper addresses the question of how the presumption-rent system has developed during ten years of its introduction to the rental market, with a particular emphasis on the investors’ perspective. The study has three focus areas, firstly an emphasis on how the real estate investors within the private and public sectors reacted to the introduction of the presumption-rents. Secondly, it examines whether the trends have changed during the course of these ten years. Finally, it observes how the presumption-rent system, as a rent-setting method for new residential rental constructions, is perceived and evaluated by the investors. Methodology: The empirical study focuses on the rent market in Stockholm, and it is articulated through a holistic multiple case-study of six public-and private real estate companies with rental dwellings in Stockholm. In order to examine the developments of the presumption-rent structures in these companies, a numerical analysis of the rent structures through a quasi-experimental design is as well conducted. Empirical Findings: The results in general prove that the rent-setting within the presumption rent system is unpredictable and subjective, because it is influenced by conflicting interests and different perceptions. The implication of this for the application of the presumption-rents is that it is depended on a complex, ambiguous and vague negotiation structure, rather than being based on a systematized rent-setting procedure. Furthermore, it is noted that the collective bargaining system, which sets the standards for the rent negotiations, is undergoing a slow process of change, as the law amendment in 2011 has caused paradigm-shits within the rental market. One dimension of this is that the rent-negotiations noticeably do not influence the investment decisions anymore, but the rent negotiations certainly have an impact on the rent-setting method. The implication for the application of the presumption-rentsystem, including its negotiation framework, is that it is applied when it meets the criteria for the investment decision, otherwise it is ignored. Finally, it is showed that nor the public neither the private companies perceive the presumption-system as a long-term and sustainable solution to the prevailing challenges with the Swedish rent-setting system. What is clear is that the system is mainly considered as a temporality solution to a course of disorders that have emerged from prolonged institutional negligence and error that have impaired the rental markets.
