What is Loan-to-Value (LTV) Ratio?
Loan-to-Value (LTV) ratio is one of the most important factors lenders use to determine how much money they are willing to lend for a home build. The LTV ratio compares the loan amount to the appraised value of the home and is expressed as a percentage.
Here is the LTV Formula:
For example, if your home is appraised at $500,000, and you need a $400,000 loan: This means the lender is covering 80% of the home’s value, while you provide the remaining 20% as a down payment. $400,000/$500,000 = 80%
Why is LTV Important in Home Build Financing?
Lenders use the LTV ratio to assess risk. A higher LTV means more risk for the lender, which could lead to higher interest rates, private mortgage insurance (PMI), or stricter approval requirements.
How LTV Affects Construction Loans:
Lower LTV (Below 80%): Easier approval, lower interest rates, and potentially no PMI.
Higher LTV (Above 80%): Stricter underwriting, possible PMI requirements, and higher interest rates.
Maximum LTV for Construction Loans: Most lenders require an LTV of 80% or lower, though some may allow up to 85-90% with additional requirements.

How to Lower Your LTV Ratio for a Home Build
A lower LTV makes your loan less risky and can lead to better financing terms. Here’s how to reduce your LTV ratio:
Increase Your Down Payment: A larger upfront payment reduces the loan amount, lowering your LTV.
Buy Land with Cash: If you already own the land, lenders count it as equity, reducing the LTV.
Choose a More Affordable Build: Lowering your total construction costs keeps the LTV manageable.
Boost Your Credit Score: While not directly affecting LTV, a higher credit score can lead to better loan terms, even with a higher LTV.
Loan-to-Value Requirements for Owner-Builders
If you’re acting as your own general contractor, the lender may require a lower LTV, typically around 70-75%, to offset additional risk. This means you’ll need a higher down payment compared to a traditional home loan.
Key Considerations for Owner-Builders:
A strong financial profile (high credit score, steady income) improves loan approval chances.
Some lenders allow land equity as part of the down payment.
Documenting builder experience can help secure higher LTV limits.
Final Thoughts: Plan Ahead for LTV Success
Understanding Loan-to-Value (LTV) ratio is essential when financing your custom home build. By strategically managing your down payment, construction costs, and land equity, you can position yourself for a better loan approval process and lower borrowing costs.
