You don't pick the home loan insurance company and you can't work out the costs. To put it simply, when purchasing or re-financing a house with a traditional mortgage, if the loan-to-value (LTV) is more than 80% (or equivalently, the equity placement is less than 20%), the consumer will likely be required to bring exclusive mortgage insurance policy. It appears unAmerican, but that's what occurs when you get a home mortgage that exceeds 80 percent loan-to-value (LTV).
