Are you buying a house?  Want to know how much your mortgage default insurance premium will cost you?  Use my calctulator below to calculate a standard mortgage insurance premium.  Mortgage default insurance is required on purchases where less than 20% is put down.  Contact me for any additional information. Please note where purchase price is above $500,000 the down payment required is 10% over and above everything over $500,000.  So if it is $600,000, then it becomes 5% of the first $500,000, which is $25,000 + 10% of the additional $100,000 which is $10,000, making the total down payment $35,000.
