This can (and will) impact your mortgage payment from the very first month.<\/p>\n<p>Here\u2019s what you need to know about mortgage loan rate locks, what they can do for you, and when and how you can put one in place.<\/p>\n<p>\n\n\n\n\n<div class=\"geo-cta widget-cta widget-cta--content     widget-cta--dark widget-cta--dark-blue-gradient\">\n    <div class=\"widget-element--content\">\n        <div class=\"widget-element--content-header\">\n            <img decoding=\"async\" alt=\"homelight logo\" class=\"widget-element--logo\" src=\"https:\/\/www.homelight.com\/blog\/wp-content\/themes\/ccprototypev5\/images\/logo-small-cta.png\" width=\"106\" height=\"25\" \/>\n        <\/div>\n        \n                <h3 class=\"cta-headline widget--bold\">Find a Top Buyer\u2019s Agent to Guide You<\/h3>\n                        <p>HomeLight can connect you with a top real estate agent familiar with the mortgage application process and home listings in your area.

Locking in a rate is an essential step to getting a home loan.<\/p>\n<p>When you sign the papers to finalize the loan, <em>that<\/em> will definitely lock in the rate. However, a mortgage loan rate lock is also something you can do much earlier in the process. It\u2019s an important way to manage risk and control costs.<\/p>\n<p>As you already know (or will soon learn), the interest rate on your home loan is one of its most important features. A lower rate is better because it means you\u2019ll be paying less interest, and the loan won\u2019t cost you as much over time.<\/p>\n<p>The <a href=\"https:\/\/www.homelight.com\/mortgages\/rates\">interest rate<\/a> can noticeably affect your monthly payment \u2014 the higher the rate, the bigger your payment will be. And over the life of a typical mortgage, even small differences in the loan\u2019s interest rate can make a difference of thousands or even tens of thousands of dollars in the total amount you\u2019ll pay to own your house free and clear. (More on that in a minute.)<\/p>\n<p>With this in mind, when you\u2019re shopping for a loan, the interest rate that lenders offer will be a major consideration. However, interest rates change constantly according to the tides of the financial markets. The rate you are quoted today is only today\u2019s rate. Tomorrow\u2019s rate is often not the same.<\/p>\n<h2>Remember: The loan process takes time<\/h2>\n<p>It typically takes <a href=\"https:\/\/www.homelight.com\/blog\/buyer-how-long-does-it-take-to-close-a-home-loan\/\">4-6 weeks to close<\/a> on a mortgage loan. Your lender needs that time to evaluate your loan request and prepare the necessary documents.<\/p>\n<p>During that time, interest rates can \u2014 and often do \u2014 go up or down by significant amounts. So how can you be sure that the interest rate that attracted you to your lender and your loan will actually be the rate on the loan documents you eventually sign?<\/p>\n<p>The answer is the mortgage loan rate lock. Some lenders and brokers may also refer to it as a lock-in or rate commitment. By any name, this is an agreement your lender makes to guarantee that the interest rate you agree to pay today will be the rate on your loan documents when you sit down for closing.<\/p>\n<p>Without a rate lock, the interest rate you finally agree to may have floated above what you planned to pay. It may make the loan a lot less attractive. It may even be more than you can afford!<\/p>\n<p>Luckily, a rate lock is a common feature of most loans. Many experts not only recommend rate locks to others but also use rate locks themselves when they are taking out a mortgage.<\/p>\n<p>\u201cWe have a wide range of customers \u2014 like myself \u2014 who always immediately lock as soon as they can,\u201d says <a href=\"https:\/\/www.linkedin.com\/in\/john-b-37a8b14\/\">John Boyles<\/a>, a mortgage expert with more than 20 years of experience. \u201cI never float. If it\u2019s a rate I like, I take it.\u201d<\/p>\n<h3>Rate locks as a risk management tool<\/h3>\n<p>Boyles explains that he is a risk-averse borrower. More certainty around the cost of the money he\u2019s borrowing gives him peace of mind.<\/p>\n<p>It also lets him plan for the future with confidence because he can correctly anticipate his mortgage payment amount. That\u2019s also true of ordinary borrowers who are similarly wary of taking on too much risk.<\/p>\n<p>\u201cWhen they lock their loans, they\u2019re transferring the risk of the rate rising during the time it takes to process the loan,\u201d Boyles explains. \u201cThey\u2019re giving it to the lender, broker, or loan officer, so they are now responsible for handling that interest rate risk.\u201d<\/p>\n<p>This doesn\u2019t mean you have to agree to a rate lock. But it may suggest that a rate lock is something to look into. To begin, let\u2019s check out the major features of a mortgage loan rate lock.<\/p>\n<div id=\"section--2\" data-toc-header=\"Elements of a mortgage rate lock\" data-toc-type=\"head\"><\/div>\n<h2>The main elements of a mortgage loan rate lock agreement<\/h2>\n<p>Here\u2019s what is covered in a typical rate lock agreement:<\/p>\n<ul>\n<li aria-level=\"1\"><strong>The date the rate lock agreement<\/strong> goes into effect; usually, this is the day you agree to the lock<\/li>\n<li aria-level=\"1\"><strong>The date the rate lock expires<\/strong> \u2014 typically 30, 60, or 90 days from the date it starts<\/li>\n<li aria-level=\"1\"><strong>The actual rate you\u2019re locking<\/strong> in (expressed as a percentage)<\/li>\n<li aria-level=\"1\"><strong>The cost of the rate lock <\/strong>\u2014 shorter rate locks are often free, but lenders may ask you to pay 0.25% to 0.50% of the loan amount for a longer rate lock<\/li>\n<li aria-level=\"1\"><strong>The mortgage program you\u2019re using<\/strong>, including whether your <a href=\"https:\/\/www.homelight.com\/mortgages\/rates\">mortgage rate<\/a> is fixed (set for the life of the loan) or adjustable (will fluctuate, typically after an introductory fixed period), and the loan term, such as 15 or 30 years<\/li>\n<li aria-level=\"1\"><strong>Any discount points <\/strong>you may be <a href=\"https:\/\/www.homelight.com\/blog\/buyer-closing-costs-for-buyer\/\">paying to get<\/a> the offered rate<\/li>\n<\/ul>\n<p>A rate lock agreement often will include a <a href=\"https:\/\/www.chase.com\/personal\/mortgage\/education\/financing-a-home\/float-down-option\">float-down provision<\/a> that describes what happens if rates go down before your closing. It also covers what happens if you don\u2019t close the loan before the rate lock expires.<\/p>\n<div id=\"section--3\" data-toc-header=\"Why would you want a mortgage rate lock?\" data-toc-type=\"head\"><\/div>\n<h2>Why would you want a mortgage rate lock?<\/h2>\n<p>The short answer to why you might want a rate lock is simply because rates are moving constantly, and even small changes can add up to a lot of money over years and decades.<\/p>\n<p>Historical rate information from <a href=\"https:\/\/www.freddiemac.com\/pmms\/pmms_archives\">Freddie Mac<\/a> shows that rates are almost never the same from one month to the next. While most monthly differences are around one-tenth of one percentage point or thereabouts, it\u2019s not unusual for rates to vary by as much as a quarter of a percentage point or more during the course of a single month. That might sound like a small amount, but these fluctuations can make a significant difference in your monthly payment.<\/p>\n<p>Let\u2019s look at an example: You are buying a $300,000 home and putting $60,000 down (20% down). You\u2019ll borrow $240,000 with a 30-year mortgage, and you can lock in your interest rate today at 6.5% without spending money on points (which you buy upfront to decrease your mortgage interest rate).<\/p>\n<p>If you lock your rate in today, your estimated monthly payment will be $1,767, including estimated escrow payments for taxes and insurance. Over the 30-year life of the loan, you\u2019ll pay a total of $396,120 interest.<\/p>\n<p>Now consider if, in this hypothetical example, you decide not to lock in your rate. By the time you close, rates have climbed to 6.75%. This quarter of a percentage point difference means your monthly payment will now be $1,807, and the total interest you\u2019ll pay has climbed to $410,520. That\u2019s an increase of $14,400 over the life of the loan.<\/p>\n<p>The $40 increase in the monthly payment might not seem significant, but remember that any increase in the monthly payment increases your <a href=\"https:\/\/www.homelight.com\/blog\/buyer-debt-to-income-ratio-for-mortgage\/\">debt-to-income ratio<\/a>. This metric compares your total monthly debt payments to your total income. If this figure slips below the acceptable level \u2014 many lenders look for a ratio below 43% \u2014 you may have to come up with a bigger down payment to qualify for a loan.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Learn about a mortgage loan rate lock, rate lock extensions, and other considerations for your loan.<\/p>\n","protected":false},"author":226,"featured_media":39331,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"content-type":"","cybocfi_hide_featured_image":"","footnotes":""},"categories":[192,620,697],"tags":[],"class_list":["post-20402","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-for-buyers","category-buy-house","category-market-news"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.0 (Yoast SEO v27.0) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Mortgage Loan Rate Lock: A Guide for Buyers<\/title>\n<meta name=\"description\" content=\"How much can a mortgage loan rate lock save you over the duration of your mortgage?
