Buying a home, refinancing or taking out a loan backed by equity comes down to more than just monthly payments—it’s a game of percentages. One number that quietly affects nearly everything about your financing is loan-to-value ratio (LTV).
Lenders use LTV to assess how much of the property’s value they’re being asked to finance. A higher LTV means more risk for them and, often, higher costs for you. The good news is, this is one item you can control and plan around. Let’s look at the LTV process, the ways in which lenders use it, and how to make it work in your favor.
Loan-to-value compares the size of your loan to the appraised value (or purchase price) of the home:
LTV = Loan Amount ÷ Appraised (or Purchase) Value × 100
For example, if you’re buying a home for $250,000 and borrowing $200,000, your LTV is 80%.
The higher the LTV, the more you're borrowing relative to property worth, and the greater risk to the lender if values fall or you can't repay. Lower LTV, on the other hand, means higher equity and less risk.
If you have more than one mortgage on the property—a first mortgage and home equity line of credit (HELOC), for instance—lenders use combined loan-to-value (CLTV) to calculate total exposure.
CLTV = Total of All Loan Balances ÷ Value of Property × 100
For instance, let’s assume your property is worth $400,000 and you carry a mortgage balance of $280,000 and a HELOC balance of $40,000. Your CLTV is 80%.
CLTV can be critical when you’re applying for more funds or refinancing.
A few critical LTV percentages have a significant impact on how your application is handled, priced and approved. Some breakpoints—especially 80%, 90% and 95%—are “toll gates.” Getting above them can introduce new requirements or costs.
Lenders value equity because it helps control their risk. Here are some common ways it can affect your loan.
Lower LTV generally means better rates. At 80% or lower, you’ll most likely receive the most flexible terms from the lender. At 90%, you might have to pay an extra 0.25% to 0.5%. If your LTV is more than 95% your loan options can become somewhat restricted.
Over the life of a 30-year mortgage, even a difference of 0.25% in rate can translate into thousands of dollars in additional interest, showing how a modest LTV improvement can offer long-term savings.
Conventional loans with an LTV of more than 80% typically have private mortgage insurance (PMI) charges. This additional payment reimburses the lender if the loan is in default. PMI typically ranges between 0.3% and 1.5% of your loan annually, based on your credit score and LTV.
The higher the LTV and the lower your credit, the more you’ll pay. However, PMI isn’t forever. It can be removed once your LTV drops to 80%, either through regular payments or home appreciation confirmed by a new appraisal. By law, lenders must cancel PMI automatically when your LTV reaches 78%, provided your loan is current.
Of course, rules can differ for government-backed loans. FHA loans, for example, typically require mortgage insurance for the life of the loan unless you refinance to a conventional loan once you have built up enough equity.
When you refinance, your loan-to-value ratio recalculates based on your new loan amount and your home's current appraised value. If your home has appreciated, or if you've paid down quite a bit of your balance, you may find that your LTV is now below a critical threshold.
That shift can be an opener. A lower LTV can allow you to cancel PMI, qualify for lower rates or receive other credit products. For rate-and-term refinances, lenders will commonly request an LTV of 80% or below in order to extend their best rate and lowest fees to you.
Cash-out refinances are more limited. As you're tapping your equity, lenders typically cap the LTV at 80%, sometimes less, depending on the loan and property type. If your current LTV is too high, it might reduce the amount of cash you'll qualify for or even knock you out of a cash-out refi.
Knowing where your LTV stands before applying can help you determine whether it is time or whether it is wiser to wait and build more equity to achieve maximum results.
When your LTV is outside conventional levels for meeting, there are several loan programs that are designed to work with minimal equity or smaller down payments.
These loans can be good choices, especially for first-time homebuyers or low-equity homeowners. They might, however, have stricter qualifications, higher insurance costs or geographical property restrictions, so shop carefully before enrolling.
If you’re near a major LTV threshold, such as 90% or 80%, minor financial adjustments can pay large dividends. Here are a few steps to adjust your ratio and improve your situation prior to applying.
A healthy loan-to-value comes with concrete benefits: You’ll be paying less to borrow and have greater flexibility down the line if you ever must fund another purchase. By making clever moves—like offering more cash down, keeping your loan size small and making your move when you ought to—you can reduce your LTV and boost your financial freedom.
In real estate finance, numbers and percentages speak the loudest. Make sure your LTV is saying the right words.
