Review Comment:
   I think this LoanAplicationBuilder Logic must be extracted to an new helper 
function. So that it is easier to read. 
   
   and group this chaining maybe like this
   
   // Loan basics
   .currency(...)
   .principal(...)
   .repaymentsStartingFromDate(...)
   
   // Term & frequency
   .loanTermFrequency(...)
   .numberOfRepayments(...)
   .repaymentEvery(...)
   .repaymentPeriodFrequencyType(...)
   
   // Interest configuration
   .interestRatePerPeriod(...)
   .annualNominalInterestRate(...)
   .interestRatePeriodFrequencyType(...)
   .interestMethod(...)
   
   // Day count conventions
   .daysInMonthType(...)
   .daysInYearType(...)
   .daysInYearCustomStrategy(...)
   
   // Flags & options
   .isDownPaymentEnabled(false)
   .allowPartialPeriodInterestCalculation(...)
   
   // Technical
   .mc(mc)
