ELI5: Explain Like I'm 5

1% rule

The 1% rule means that if you want to buy a house or property, you should spend no more than 1% of the total price of the house on monthly mortgage payments. For example, if you buy a $100,000 house, your monthly mortgage payments should be no more than $1,000. This means you should be able to afford the cost of the house without getting into too much debt.
