The most common variant of construction financing is the annuity loan with subsequent follow-up financing. Due to the constant monthly instalments, the negative interest rate to be paid decreases at the same time as the amount of credit falls. This, in turn, benefits the repayment and causes it to rise continuously. In addition to the classic, there are also other possibilities to trade a construction financing. The greatest security is provided by the full-payer loan. Here, the complete financing is planned up to the debt-free, without having to accept follow-up financing. On the other hand, if you are very willing to take risks, you can take a look at loans with a variable interest rate. In this variant, the interest rate of the loan increases or decreases, depending on the current market situation. Associated with this, however, the monthly repayment rate also increases or falls, which makes sensible planning very difficult.
