Mortgage Extras: Points, Rent vs. Buy, and Extra Payments
Mortgage discount points break-even, rent vs. buy comparison, extra payment payoff timing, and currency conversion for cross-border buyers.
Beyond the basic mortgage payment calculation, these four decisions come up constantly for homebuyers and existing homeowners.
Mortgage points: do they pay for themselves in time?
Paying $3,000 upfront to drop a rate from 6.5% to 6.25% on a $300,000, 30-year loan saves a specific amount per month — dividing the point cost by that monthly savings gives a break-even period. If you'll own the home well beyond that break-even point, paying points is worth it; if you might sell or refinance sooner, it usually isn't.
Rent vs. buy: comparing true monthly costs
Renting at $1,800/month looks straightforward, but buying involves more than the mortgage payment alone — adding property tax, insurance, and estimated maintenance to a $1,896 mortgage payment might bring the true monthly ownership cost to around $2,446, a meaningfully different comparison than mortgage payment alone would suggest.
Extra payment payoff: shortening a 30-year loan
Adding a fixed extra amount to every monthly payment reduces both the payoff timeline and total interest paid, since extra payments go entirely toward principal. Even a modest extra $200/month on a $300,000 loan can shave years off a 30-year term.
Currency conversion: for cross-border buyers
Converting $500 at a rate of 0.92 gives approximately 460 in the target currency — a straightforward multiplication, but essential for budgeting a cross-border purchase or down payment when the sale price is quoted in a different currency than your savings.

Points, rent-vs-buy, extra payments, and currency all involve a specific trade-off worth calculating rather than guessing at. Try the mortgage points calculator, rent vs. buy calculator, extra payment payoff calculator, and currency conversion calculator.
