80% or lower is the practical benchmark — at that level, conventional lenders waive PMI and reserve their best pricing. Many first-time buyers start at 90%–97% LTV and work down through scheduled payments and appreciation. For refinance products, lenders generally want 80% or lower, especially for cash-out transactions.

On conventional loans, PMI is required whenever your LTV exceeds 80% at origination. FHA loans charge an upfront Mortgage Insurance Premium plus an annual MIP regardless of LTV, and on most FHA loans MIP runs for the life of the loan when the original LTV is above 90%. VA loans use a one-time funding fee instead, and USDA loans use a comparable guarantee fee.

You can lower the numerator or raise the denominator. Pay down principal faster through extra monthly payments, biweekly schedules, or lump sums from bonuses and tax refunds. On the value side, the home can appreciate organically with the market, or you can document a higher value with strategic, high-ROI renovations such as kitchen and bath updates.

LTV considers only the first mortgage. Combined LTV (CLTV) adds the balances of all liens against the property — the primary mortgage plus any second mortgages, home equity loans, or HELOC balances — divided by the property value. Most lenders cap CLTV at 80%–90% when underwriting a new junior lien, so CLTV is the relevant ratio if you plan to open a HELOC.

Yes, materially. Conventional pricing uses Loan-Level Price Adjustments (LLPAs) tied to LTV and credit score. A 60% LTV with a 760 FICO can get the lender's best advertised rate, while a 95% LTV with a 660 FICO can add 1.5%–2.5% in points to the same nominal rate. Lower LTV almost always means cheaper money.

A licensed appraiser visits the property and uses three approaches: the sales-comparison approach (recent sales of similar nearby homes), the cost approach (land value plus current cost to rebuild, minus depreciation), and, for income properties, the income approach. Lenders typically use the appraised value or the contract price, whichever is lower, as the LTV denominator on a purchase.

Under the Homeowners Protection Act, you can request cancellation in writing once the principal balance reaches 80% of the original value, provided you are current on payments and the loan has a good payment history. PMI auto-terminates at 78% LTV based on the original amortization schedule. If you are using appreciation to reach 80% LTV early, lenders typically require a new appraisal at your expense.

You are 'underwater' — the unpaid balance exceeds the home's value. Selling on the open market requires bringing cash to closing to settle the loan. Traditional rate-and-term and cash-out refinances are generally unavailable above 100% LTV. Options include holding the property while paying down principal, pursuing a streamline refinance with the same servicer if eligible, or, in severe cases, a short sale or modification.

No. FHA permits LTV up to 96.5% for borrowers with a 580+ FICO score, and up to 90% for scores between 500 and 579. FHA also requires Mortgage Insurance Premium (MIP) regardless of LTV — an upfront premium plus an annual premium that lasts the full loan term when the starting LTV is above 90%. To stop paying MIP, borrowers usually need to refinance into a conventional loan once they reach 80% LTV.

Cash-out refinance LTV caps are stricter than rate-and-term limits. Fannie Mae and Freddie Mac generally cap cash-out at 80% LTV on a primary residence and 75% on a second home or investment property. FHA permits cash-out to 80% LTV. Above those caps, you typically cannot pull equity out as cash, even if your underlying credit is strong.

On a purchase, lenders use the lower of the appraised value or the contract price as the denominator. If you negotiate a price below appraisal, the appraisal does not increase your loan amount. On a refinance or HELOC, only the new appraisal matters — the original purchase price is no longer part of the calculation.
