Bostadsbyggandet har de senaste åren ökat kraftigt och det kommer fortsätta att öka de kommande åren. Det ökade byggandet har bidragit till en större marknad för nyproduktionsförmedling. En större marknad som delvis också beror på ökade bostadspriser på successionslägenheter som en följd av Coronapandemin. Vid nyproduktion är kostnadskalkylen den fundamentala grunden för köpet och de framtida kostnaderna för köparen. Kostnadskalkylen är även ett viktigt material i förmedlingen för mäklaren.  Förhandsavtal har fått mycket medial uppmärksamhet de senaste åren. Det har även intygsgivning av kostnadskalkyler och ekonomiska planer fått. Intygsgivare har visat sig vara ett större problem än befarat men det största problemet finns i lagstiftningen. Problematiken som diskuteras leder framförallt till att köparen köper en bostad utan att egentligen veta vad de köper då kostnadskalkylen är svårtolkad och saknar tydliga riktlinjer och nyckeltal. Det ställer stora krav på mäklarens kompetens inom nyproduktion. Något som inte är en del av den obligatoriska utbildningen.  I uppsatsen har intervjuer genomförts med bostadsutvecklare, fastighetsmäklare och intygsgivare i Stockholm för att sammanställa synen på kostnadskalkylen och vilken problematik som finns idag vad gäller förmedling av nyproducerade bostadsrätter. Intervjuerna tillsammans med en djupdykning i teorin av lagstiftning och artiklar gav upphov till resultatet som presenteras i slutet av arbetet. Syftet med uppsatsen har varit att undersöka när förändringar i kostnadskalkylen sker och vad det får för konsekvenser för mäklarens förmedlingsprocess, samt ge förslag på lösningar för att minimera eller åtgärda problemen. / Housing construction has increased considerably in recent years and will continue to increase in the forthcoming years. The increased construction has contributed to a larger market for newly built condominiums. A larger market that is partly also due to increased housing prices for succession apartments as a result of the Corona pandemic. In new development, the cost calculation is the fundamental basis for the purchase and the future costs for the buyer. The cost calculation is also an important document in the brokerage for the broker.  Contracts made in advance have received a lot of media attention in recent years. Certification of cost calculations and financial plans has also received some media coverage. Certifiers have proven to be a bigger problem than feared, but the biggest problem is in the legislation. The problems that are discussed primarily lead to the buyer buying a home without really knowing what they are buying as the cost calculation is difficult to interpret and lacks clear guidelines and key figures. This places great demands on the broker's expertise in new development. Something that is not part of the compulsory education.  In the essay, interviews were conducted with housing developers, real estate agents and certifiers in Stockholm to compile the view of the cost calculation and to get a bitter view of what problems exist today regarding the mediation of newly produced condominiums. The interviews together with delving into the theory of legislation and articles gave rise to the results that are presented at the end of the work. The purpose of the thesis has been to investigate when changes in the cost calculation occur and what the consequences are for the broker's brokerage process, as well as provide suggestions for solutions to minimize or remedy the problems.

The largest post-war economic crisis, which began spreading to the world in the second half of 2008, hit all sectors negatively. An important lesson from the analysis of the crisis is not its causes, but rather the reference to the drawbacks of globalization, in the form of dismantling the consequences of this crisis. Building industry is a specific branch of the Czech economy, which has responded to the outbreak, the course and the retreat of crisis, in a unique way. Both pre-investment and investment phases of a construction project are time-consuming, resulting in a delayed response - inertia, to changes in the state of the economy that are reflected in aggregate demand from which demand for construction output is derived. The thesis focuses mainly on the development market, where it focuses in detail on evolution of housing construction in the pre-crisis, crisis and post-crisis period. The set of incorrect steps, decisions and inactivity of residential developers caused a unique phenomenon - the house-offer crisis. Therefore, the result of the work is methodological recommendations - a set of steps whose observation should reduce the negative effects of the crisis on the construction industry and avoid the re-emergence of the house-offer crisis. Economic cycles give us two assurances: each growth is followed by fall and vice versa. Nowadays it is not possible to predict the causes of the future crisis or its length, but it is important to prepare for it.
