mortgage-roadmap 0.1.1

mortgage_calculator:

mortgage_calculator

Repository that calculate the mortgage roadmap of two types of mortgage calculators:

• Mortgage_Constant_ChargeOff: Mortgage roadmap where you pay an constat chart off each month
• Mortgage_Constant_Pay: Mortgage roadmap where you pay an constat fee each monthmap

How it work:

1. Create en python environent and install the package using de command:

   pip install mortgage-roadmap
   

2. Once you get installed the package you can import the packahe in the python module by:

   • import the classes:

     from mortgage_roadmap import ( Mortgage_Constant_ChargeOff, Mortgage_Constant_Pay )
     

   • import the module:

     import mortgage_roadmap 
     

Examples:

1. Basic exaple where we import the nodule with all the classes. Then we change the amount of units that we will as output. Thrn we create a dataframe as output an as last we export the information in an excel file

from mortgage_roadmap import *
Mortgage_Constant_ChargeOff.setDecimals(4)

a = Mortgage_Constant_ChargeOff(100000., 50, 4,8)

a.create_Dataframe

{'roadmap': [{'dept': 133543.56, 'charge_off': 1456.44, '.....'

a.create_XLSX_File('data/xlsx/mortgage_inform.xlsx')

Compatibility:
