Real estate math is often the most intimidating section for candidates preparing for the Kentucky Real Estate Commission (KREC) licensing exam. However, mastering core financial formulas is essential not just for passing your test, but for effectively guiding future buyers through the complex world of real estate financing. For a comprehensive overview of everything you need to know to pass your test, be sure to bookmark our Complete Kentucky Exam Guide.
Two of the most critical math concepts you will encounter are Loan-to-Value (LTV) ratios and down payment calculations. These figures dictate a buyer's purchasing power, their need for mortgage insurance, and their eligibility for local programs like those offered by the Kentucky Housing Corporation (KHC). This guide will break down the formulas, provide Kentucky-specific examples, and share the "trick" scenarios exam writers love to use.
Understanding the Loan-to-Value (LTV) Ratio
The Loan-to-Value (LTV) ratio is a metric used by lenders to assess the risk of a mortgage loan. It represents the relationship between the amount of money being borrowed and the appraised value (or purchase price) of the property. A lower LTV means less risk for the lender, which usually translates to better interest rates for the borrower.
The "Golden Rule" of LTV Calculations
If there is one rule you must memorize for the Kentucky real estate exam, it is this: Lenders base the LTV on the purchase price OR the appraised value—whichever is LESS.
Exam writers frequently try to trick candidates by providing a property that appraised for more than the purchase price, hoping you will calculate the loan based on the higher appraisal. Always choose the lower number.
The LTV Formula
The formula for calculating LTV is straightforward:
- LTV Ratio = (Loan Amount ÷ Lesser of Appraised Value or Purchase Price) × 100
Conversely, if you know the LTV percentage the lender is willing to offer and the value of the property, you can calculate the maximum loan amount:
- Maximum Loan Amount = (Lesser of Appraised Value or Purchase Price) × LTV Percentage
Down Payment Calculations
The down payment is the upfront portion of the purchase price that the buyer pays out of pocket. It is the inverse of the LTV ratio. For example, if a lender offers an 80% LTV loan, the remaining 20% of the purchase price is the required down payment.
The Down Payment Formula
- Down Payment = Purchase Price - Loan Amount
- OR
- Down Payment = Purchase Price × Down Payment Percentage
When helping a client transition from a rental agreement—which you can learn more about in our guide to Kentucky lease types and terms—to homeownership, understanding exactly how much cash they need to bring to the closing table is a vital fiduciary duty.
Typical Minimum Down Payments
Different loan programs have different minimum down payment requirements. The chart below illustrates the standard minimums you should know for the exam:

Kentucky-Specific Considerations: KHC Programs
While federal lending guidelines (like FHA and VA loans) apply nationwide, Kentucky real estate agents must also be familiar with the Kentucky Housing Corporation (KHC). KHC offers Down Payment Assistance (DPA) programs that help first-time and repeat homebuyers across the Commonwealth.
KHC programs often provide assistance in the form of a secondary loan (up to a certain amount, such as $10,000) to cover the down payment and closing costs. When calculating the primary loan's LTV for a KHC buyer, the primary mortgage might be 96.5% (FHA), while the secondary KHC loan covers the remaining 3.5%. Understanding how these layered financing options work is crucial for serving diverse communities in Kentucky.
Note: Financing regulations and state assistance programs evolve frequently. Keeping up with these changes is a major reason why financing topics are heavily featured in Kentucky continuing education requirements.
The Impact of LTV on Mortgage Insurance
On the licensing exam, LTV isn't just about math; it's about applying the math to real-world lending rules. If a buyer's LTV on a conventional loan is greater than 80% (meaning they put down less than 20%), the lender will require Private Mortgage Insurance (PMI).
For FHA loans, a Mortgage Insurance Premium (MIP) is required regardless of the LTV, though the LTV dictates how long the borrower must pay the premium (e.g., 11 years vs. the life of the loan).
Exam Tip: If an exam question asks how a buyer can avoid paying PMI on a conventional loan, the answer is always to achieve an LTV of 80% or lower, either through a 20% down payment or by utilizing a piggyback loan.
Exam Prep Scenarios for Kentucky Candidates
Let's walk through a multi-step math problem typical of the KREC licensing exam.
Scenario 1: The Low Appraisal
The Setup: A buyer enters into a purchase agreement for a home in Lexington for $250,000. The buyer is seeking a conventional loan with an 80% LTV. During the underwriting process, the property appraises for $240,000. How much cash must the buyer bring to closing for the down payment if the seller refuses to lower the purchase price?
The Solution:
- Determine the value the lender will use. The rule is the lesser of the purchase price ($250,000) or the appraisal ($240,000). The lender uses $240,000.
- Calculate the maximum loan amount: $240,000 × 0.80 (80%) = $192,000.
- Calculate the total cash needed to close the gap. The buyer must pay the difference between the agreed purchase price ($250,000) and the loan amount ($192,000).
- $250,000 - $192,000 = $58,000.
If the property had appraised for the purchase price, the down payment would have been only $50,000. The low appraisal forced the buyer to bring an extra $8,000 to the table.
Scenario 2: Commercial LTV and ADA Compliance
While residential transactions dominate the exam, you may see commercial math. Commercial lenders often require lower LTVs (e.g., 65% to 75%). Furthermore, commercial buyers might need to factor in renovation costs for accessibility, a topic covered extensively in our guide to Kentucky ADA compliance in real estate. If a commercial building costs $1,000,000 and the bank requires a 70% LTV, the maximum loan is $700,000, meaning the investor must have $300,000 in liquid capital for the down payment.
Frequently Asked Questions (FAQs)
Will I get a calculator on the Kentucky real estate exam?
Yes. You are permitted to bring a basic, non-programmable, silent calculator to the PSI testing center. Financial calculators or calculators on smartphones are strictly prohibited.
Does the earnest money deposit count toward the down payment?
Yes. The earnest money deposit is held in an escrow account (often by the broker) and is credited toward the buyer's down payment and closing costs at the time of settlement.
How does a low appraisal affect the down payment for a Kentucky buyer?
Because lenders calculate LTV based on the lesser of the purchase price or appraised value, a low appraisal reduces the maximum loan amount. If the seller will not lower the price, the buyer must increase their down payment to cover the "appraisal gap."
Are specific KHC down payment assistance rates tested on the state exam?
No. Because interest rates and specific program limits change frequently, the exam will not test you on current KHC rates. However, you are expected to understand the general concept of down payment assistance, secondary financing, and how it affects the primary loan's LTV.
What is the standard LTV required to avoid Private Mortgage Insurance (PMI)?
For conventional loans, an LTV of 80% or lower is required to avoid PMI. This means the buyer must make a down payment of at least 20% of the property's value.
