Financial planners don’t just help people balance their budgets or plan for retirement; they also help their clients buy homes. After all, a house is very often the biggest financial investment you’ll ever make—so, it makes sense that these professionals would have some strong opinions on just how to go about it.

Curious what they want you to know? Read on for their top, no-nonsense tips.

1. Buy only if you plan to stick around

When you purchase a house, you have to shell out a significant amount of cash for closing costs—fees paid to third parties that helped facilitate the sale. Closing costs can vary widely by location, but they typically total 2% to 7% of the home’s purchase price. So on a $250,000 home, your closing costs would amount to anywhere from $5,000 to $17,500. That’s a serious chunk of change!

Consequently, Craig Jaffe, a certified financial planner at United Capital in Boca Raton, FL, says it’s important to calculate your break-even point—i.e., how long it will take for you to recoup those costs.
