The Swedish residential rental system and market has been discussed and criticized diligently the past years. A reformed rental law was therefore the 1 stof January 2011 implemented. This has the purpose to better reflect the consumer’s priorities with a more market related rental determination. With this change, it is of interest to compare it to another rental system, with market rents. In the German rental system, free rental setting is allowed in new leases. This thesis aims to evaluate and compare the rental system in Sweden and Germany. The comparison was done after reading several reports, articles and literature as well as interviews with Swedish and German actors. Results show that the reformed Swedish law will not lead to major changes, though it might lead to a more adequate rental determination system. The analysis of the German system, with its free rental setting for new leases show that is better functioning than the Swedish. It is however positive that the new Swedish law incorporates more market related variables, even though the determination of a market rent is quite complex. A free rental setting allocates diversity in the market and contributes to a heterogeneous market, as it is possible to meet different consumers demand. The rental market can be expanded though, with a free rental setting when subletting condominiums. A conclusion from the analysis is that Sweden should strive to adopt a German system with free rental setting in new leases.

Den nuvarande bostadshyresmarknaden i Stockholm är allt annat än välfungerande. Det låga utbudet av hyresrätter har bland annat resulterat i långa bostadsköer, en omfattande svart hyresmarknad och inlåsningseffekter. I skenet av denna illa fungerande hyresmarknad reser sig frågan om det inte är på tiden att reformera alternativt frångå det nuvarande bruksvärdesystemet, till förmån för en ny alternativ hyressättningsmodell. En modell som förhoppningsvis reducerar de negativa effekterna vi idag ser på hyresmarknaden. Rapporten har som utgångspunkt att beskriva dagens hyressystem samt redogöra för potentiella hyresmodeller. Nuvarande hyressystem och de potentiella modellerna är alla relativt väl utredda ur ett hyresmässigt perspektiv. Utredning gällande förslagens inverkan på marknadsvärdet beträffande fastigheterna saknas. Två av de utredda modellerna innebär en infasning mot marknadshyror. Värderingssimuleringar utförs för att fånga de eventuella marknadsmässiga värdeförändringarna dessa modeller har. För att göra välgrundade antaganden till värderingssimuleringarna hämtades nationell och internationell data från IPD och Newsec, samt kunskap från intervjuer. Det inhämtade materialet visade på ett proportionerligt samband om 0,5 – 1,5 procent differens i yielden mellan bostads – och kontorsmarknaderna runt om i Europa där hyresmarknaden i någon mån är avreglerad. Motsvarande förhållande i Stockholm ligger på 2,0 – 3,0 procent. Värderingssimuleringarna visar att en introduktion mot marknadshyror inte resulterar i markanta värdeökningar, detta då avkastningskrav samt drift – och underhållskostnader antas motverka hyresökningen. Störst genomslag på värdet noteras i det befintliga beståndet där amplituden mellan utgående hyra och marknadshyra är som störst. / The current rental housing market in Stockholm is anything but functional. The supply of rental housing is low, which has resulted in long queues, an extensive black rental market and lock in effects. The ill-functioning rental market raises the question whether it is time to reform or abandon the current rental system, in favor of a new approach in the rental market where a new alternative rent setting model would be introduced. A model that hopefully reduces the negative effects we see on the rental market today. The report sets out to describe the current rental system and outline potential rental models. Both current and potential models are all relatively well explained from a rental perspective, but none have been investigated from a market value perspective. Two of the investigated models involve a change toward market rents. Valuation simulations are performed to capture the potential market value change these models entail. To make informed assumptions in the simulations, national and international data have been collected from IPD and Newsec, as well as knowledge from interviews. The collected data showed a proportionate relation of 0.5 to 1.5 percent difference in yield between residential and office markets around Europe, where the rental housing market to some extent is deregulated. The corresponding ratio in Stockholm is 2.0 to 3.0 percent. Results from the simulations showed that an introduction to market rents do not result in a significant increase in the market value. Yields and operating - and maintenance costs is assumed to counteract the increased rent, making the value impact less significant. The greatest value impact is recorded in the existing stock where the amplitude between the outgoing rent and market rent is greatest.
