As you begin to find what you can afford for a mortgage payment, remember that there is a lot of conflict on the best percentage of your monthly income. Some people say 45% of your monthly income, others say 25%. Best practice as illustrated by the Wall Street Journal is the 28/36 rule. Landmark goes into that more on this article.
Finding 28% of your income and looking for houses that you can afford in that budget can be a quick and easy way to calculate how much you should spend on a home, however, it's arbitrary. Perhaps you're comfortable with having more debt and a longer loan. Or maybe you would rather have a shorter time-span on a loan. Here is a more specific way to find what you should be paying for housing costs each month.
First, take your monthly income "“ the amount of money that is put into your bank account each month, with taxes taken out. If you have dual income from your partner, include that as well.
Take your monthly income and subtract your set debts. This will be different for everyone "“ some people will have car payments, others will have phone bills. Add up each of these bills, but exclude anything to do with your housing costs at your current location. You should write these down, but don't include them in your equation. You can look at your housing costs currently to get a good idea of what you can afford as far as a mortgage payment goes.
Next, subtract food-related costs. If you don't have a current budget for what you spend on food (groceries, eating out), you can look back through your past two to four months of bank statements and average the amount of money you spent those months on food-related costs.
Subtract how much money you transfer to savings each month.
After, subtract entertainment costs. Again, if you don't know how much you use on entertainment each month, you can look back through your bank statements and average your costs.
This final number will be how much money you can spend per month on housing-related costs.
