PITI stands for Principle, Interest, Taxes, and Insurance and is what makes up your monthly mortgage payment. Calculating your PITI number will help you determine how much house you can afford.\r\n\r\nAs the real estate market starts to open up along with the rest of the country, and with interest rates at an all-time low, many people are considering home purchases. As you browse listings and search for your perfect property, you're probably trying to settle on exactly how much house you can afford. This is perhaps the most important question to ask yourself when it comes to buying your home is: how does this purchase fit into your overall finances? Since buying a home is likely the largest purchase most of us will ever make, there are several things you need to consider when thinking about this question. \r\n\r\nThe cost of the initial down payment isn't the only expense you'll need to calculate upfront - you also need to factor in all the expenses associated with purchasing, maintaining, and keeping the home. Your monthly mortgage, fees, taxes, insurance, home owner dues (i.e., HOA fees), and other associated costs, are all line items on the home-buying bill. All of these items will factor into your overall budget for purchasing a home. For example, maybe you can afford a down-payment on an $800,000 home, but the monthly payments will be too much of a strain. So what's the first thing to consider when it comes to your monthly payments? PITI.\r\n\r\nWhat is PITI?\r\n\r\nOne of the most important financial considerations related to your home-buying journey is what's called PITI, which stands for the sum of monthly principal, interest, taxes and insurance. This is usually calculated on a monthly basis and your lender will compare it to your monthly gross income to see if you are a viable candidate for a mortgage loan (often called the debt-to-income ratio). In the event that you might lose your income or lack enough equity or other assets, your lender may require special considerations, such as two months of PITI.\r\n\r\nSo what exactly goes into PITI? A very high-level overview of its components include:\r\n\r\nPrincipal \u2013 This is the amount of your loan, so it is likely the cost of your home minus your down payment. \r\nInterest \u2013 Just like the majority of other loans, the interest is the amount the lender charges you for borrowing money. \r\nTaxes \u2013 Real Estate tax rates vary significantly from area to area, so you should figure out just how much of your PITI goes to taxes. \r\nInsurance \u2013 Your lender may require homeowner\u2019s insurance as part of your PITI. \r\n\r\n\r\nAnother requirement from your lender that can be included in your monthly PITI is Private Mortgage Insurance (PMI). If you put down less than 20% for a down payment \u2013 even with good credit - then your lender may find your smaller down payment as a higher chance of default, thus requiring PMI. Though PMI payments can be canceled once you gain 20% equity in your home, building up to 20% can mean years of pricey PMI payments \r\n\r\nKeep in mind that PITI may just account for just some of your monthly expenses when owning a home. Depending on where you live and how you are paying for your home, there may be additional costs built in. And the components that make up PITI are very broadly defined here; there is often more complexity that goes into each part of PITI.\r\n\r\nPITI & Escrow\r\nWhile many of us have heard of \u201cescrow\u201d when it comes to home buying (and other financial transactions), one thing that is less known is that PITI is also known by lenders as your \u201cescrow account.\u201d Your monthly PITI payments go into your escrow account and your funds are disbursed to the lender for the interest, principal, property insurance (and for some, PMI), to the county for property taxes when they come due, and your insurance carrier for your homeowner\u2019s insurance. \r\n\r\nFor many first-time home owners, an escrow account is mandatory, and in many ways can be very useful. For instance, when the time comes for making the payments for real estate taxes, many find it easier to pay them monthly rather than face a large bill due at one time (or twice depending on your taxing jurisdiction.)\r\n\r\nPITI & The 28% Rule\r\nWhen it comes to calculating what you can afford regarding your PITI, a good rule of thumbs is that 28% of your gross monthly income is the maximum monthly cash outflow for costs associated with your house payments.\r\n\r\nThe 28% amount is calculated by taking the principal and interest of your monthly mortgage payment and adding one-twelfth of your annual real estate taxes (i.e., one month of real estate taxes), as well as one-twelfth of your annual homeowner\u2019s insurance premium (i.e., one month of your annual homeowner\u2019s insurance) and one-twelfth of any annual association fees (i.e., one month of your annual HOA fees). Then divide this by your gross monthly income. \r\n\r\nOne variation of this is the 36% rule, which is calculated by taking your monthly PITI as calculated above, and then adding any homeowners-association dues or condo fees, credit cards, car loans, student loans and any other personal loans. Then divide this by your gross monthly income. \r\n\r\nSo why the magic number of 28\/36? It\u2019s a \u201crule of thumb\u201d for determining the amount of debt that is generally recommended to be taken on by an individual or household so that you can maintain enough cash to afford other living expenses (food, car payments, clothing, entertainment, etc.), while still saving for retirement. \r\n\r\nOur Take\r\nPITI is just one of the many financial considerations to think of when making such a large financial commitment.
