Abstract
Ante un hipotético, pero cada vez más real, caso de riesgo de impago de una hipoteca o ante una caída en los tipos de interés, un asunto importante que se plantea el prestatario es el de la posibilidad de minimizar ese riesgo mediante la selección de la mejor opción de refinanciación. En el presente trabajo se presenta un modelo de refinanciación de hipotecas desarrollando un método de programación puramente cuantitativa, con una simulación basada en un algoritmo creado especialmente para este caso y que puede ser útil para deudores hipotecarios. Así, se comienza explicando la base teórica sobre la que se asienta la investigación, para pasar a desarrollar el problema, continuando con su implantación. Finalmente, se analizan los resultados y se comentan las conclusiones más relevantes.
Facing an hypothetical, but increasingly, case of default risk on a mortgage or a fall in interest rates, an important issue raised by the borrower is the possibility of minimizing that risk by selecting the best refinancing option. In this paper, a mortgage refinancing model is presented, developing a purely quantitative programming method with a simulation based on an algorithm created especially for this case and that can be useful for mortgage debtors. Thus, we begin by explaining the theoretical basis on which the research is based, to proceed to develop the problem, continuing with its implementation. Finally, the results are analyzed and the most relevant conclusions are commented.
