Letâs look at a hypothetical spontaneous chemical reaction: The quantity of usable energy (chemical potential) in a reaction is called the Gibbs Free Energy (DG). DG is the difference between the energy contained in the products of a reaction and the reactants: DG = (energy of products) - (energy of reactants)
That's why some financial experts feel it's more realistic to think in terms of your net income, aka take-home pay, and that you shouldn't use any more than 25% of your take-home on your mortgage payment.
For a 30-year loan with a down payment of less than 5%, your premiums will be 0.85% (down from 1.35%) of the outstanding balance each year. That cost is typically divided into 12 monthly payments and added to your mortgage payment.Thatâs $850 per year, or about $70 per month, per $100,000 of loan balance.here are smaller and more lenient down payment requirements. Most FHA mortgages require a 3.5% down payment â thatâs $3,500 for every $100,000 you borrow â and the average down payment on an FHA home loan is about 5%, according to Ellie Mae.
