Mortgage payment affordability – The ballpark maximum amount that a bank will lend based on gross income and current outstanding debt. There are exceptions and we’ll get to them later.

PITI – Acronym for Principle Interest Taxes and Insurance.

28/36 Ratio – The standard formula for mortgage affordability. Simply stated, it means that the total of PITI should be no higher than 28% of gross monthly income and the total of PITI combined with all outstanding debt should be no higher than 36% of gross monthly income.

PMI – Acronym for Private Mortgage Insurance. Required when your down payment is less than 20% of the sale price.

Mortgage payment affordability tutorial

First, establish your yearly gross income. Be prepared to furnish prior year tax returns and current W-2’s to support the basis of your income. For educational purposes, let’s say your annual gross income is $60,000.

Divide your yearly gross income by 12 to arrive at your gross monthly income. Using our $60,000 example, the calculation looks like this $60,000 ÷ 12 = $5000.

The $5000 figure becomes the basis for the 28/36 ratio. Simply multiply your $5000 monthly gross income by 28% or .28. The calculation looks like this. $5000 X .28 = $1400. The $1400 represents the front end of the 28/36 ratio. Which means based on income of $60,000, you can afford in the ballpark of $1400 a month for principle, interest, taxes and insurance (PITI).

Next, go back to your $5,000 gross monthly income and multiply it by 8% or .08. The calculation looks like this: $5,000 X .08 = $400. That $400 figure represents the back end of the 28/36 ratio and it means that all of your current outstanding debt cannot exceed $400 a month. Current debt would include credit cards, car and student loans etc.

In a nutshell, a bank will allow you to spend approximately $1800 total for your mortgage and outstanding debt, based on a $60,000 annual income. $1400 per month or 28% of monthly gross income for PITI and an additional $400 a month or 8% of monthly gross income for all your other debt, total: $1800. $1400 is your mortgage payment affordability.

Exceptions that influences lenders when making mortgage loans

Other income – If you receive income from sources like bonuses and part time jobs. You’ll usually have to show these income sources have contributed to your income for at least two years prior to your mortgage application for it to be considered.

Credit history – Everybody knows that your credit report can influence your application and even the interest rate that you’ll pay. Get a copy of your credit report and clean it up if there are problems or discrepancies.

Potential debt – Potential debt is the debt that you could incur if you were to max out your current credit lines. Basically, it’s the difference between your current outstanding balances and your total credit lines. An example would be a credit card with a $10,000 credit limit and a $500 outstanding balance. Get rid of unused credit lines or lower them to reasonable levels.

Association fees – These fees are common in condos and townhouses. They will be figured as part of your monthly mortgage payment because they are not voluntary expenditures and a necessary monthly expense associated with these types of real estate.

PMI – Another monthly expense that would be added to your monthly mortgage payment. PMI is required when putting less than a 20% down payment.
