how much money do you have to put down to avoid pmi?
One way to avoid paying PMI is to make a down payment that is equal to at least one-fifth of the purchase price of the home; in mortgage-speak, the mortgage's loan-to-value (LTV) ratio is 80%. If your new home costs $180,000, for example, you would need to put down at least $36,000 to avoid paying PMI.
