Bank loan
Down payment = 0.10 
 $ 300000 = $ 30000
Mortgage amount = $ 300000 - $ 30000 = $ 270000

Monthly payment = $1,432.96 
 $ 1433
Interest paid = $ 1433 
 360 - $ 270000
Interest paid = $ 245880

 $ 300000
Down payment = $ 60000
Mortgage amount = $ 300000 - $ 60000 = $ 240000

 $ 1824
Total interest paid = $ 1824 
 180 - $ 240000
