What it means
Loan-to-value — usually shortened to LTV — is the ratio of the loan amount to the appraised value of the property, expressed as a percentage. A buyer financing $400,000 of a home that appraises for $500,000 has a loan-to-value of 80%.
LTV sits next to debt-to-income ratio as one of the few numbers that influence almost every part of a mortgage decision: the down payment required, whether mortgage insurance applies, the rate, the loan program eligibility, and what’s possible on a future refinance.
How it’s calculated
The math is simple. The complications are in the details.
LTV = loan amount ÷ appraised value (or purchase price, whichever is lower)
A few practical notes:
- For a purchase, the lender typically uses the lower of the appraised value and the purchase price — so a property that appraises above the purchase price doesn’t reduce the LTV. The buyer’s negotiated price is what counts.
- For a refinance, the lender uses the appraised value. This is where rising property values can help an owner: equity earned through appreciation can lower the LTV and unlock options.
- For a cash-out refinance, the LTV uses the new, larger loan amount including the cash being taken out.
Why it matters
LTV influences four things at once:
- Down payment. Down payment and LTV are two sides of the same equation. A 5% down payment produces a 95% LTV; a 20% down payment produces an 80% LTV.
- Mortgage insurance. On a conventional loan, private mortgage insurance generally applies above 80% LTV and can be removed once the LTV drops below a qualifying threshold. FHA loans treat mortgage insurance differently — for most current FHA loans, removal requires a refinance.
- Pricing. Lenders price loans in tiers, and LTV is one of the tier inputs. A small change in LTV can sometimes move a loan to better pricing.
- Program eligibility. Different loan programs have different maximum LTV limits — investment property loans cap lower than primary residences, jumbo loans often cap lower than conforming, and certain specialty programs have their own thresholds.
How LTV changes over time
LTV is not static. It moves in two ways:
- Paydown. As the borrower pays principal, the loan balance drops and LTV decreases.
- Appreciation. As the property’s value rises, the same loan balance produces a lower LTV.
This matters most for the mortgage insurance question on a conventional loan. A borrower who started at 95% LTV with PMI may, after a few years of paydown and a Reno-side appreciation cycle, be in a position to remove PMI without refinancing — sometimes through an automatic threshold the lender applies, sometimes by requesting a new appraisal.
Common misconceptions
- “My LTV is based on what I think the house is worth.” The lender uses the appraisal, not the buyer’s estimate.
- “Once I’m under 80% LTV, my PMI goes away automatically.” Sometimes — depending on the program and the lender’s procedures. Many borrowers have to request PMI removal, occasionally with a new appraisal. Worth asking about specifically.
- “All loan programs care about LTV the same way.” They do not. Conventional, FHA, VA, jumbo, and investment programs each handle LTV differently, with different thresholds and different mortgage insurance treatments.
