High LTV HELOC: borrowing to 90%, 95% or 100% of your home's value

What counts as a high LTV HELOC

A high LTV HELOC is a home equity line whose combined loan-to-value (the first mortgage, other liens and the line, divided by the home's value) reaches 90% or more. That is where federal bank supervisors draw the line: their home equity guidance treats an owner-occupied loan at a combined LTV of 90% or above as high-LTV, and a non-owner-occupied one-to-four-family loan above 85%.^[1] Banks that make those loans must track them as exceptions to the supervisory loan-to-value limits unless there is extra protection, in the form of mortgage insurance or readily marketable collateral.^[1]

Extra borrowing from a higher limit = value × (new limit − old limit)$400,000 × (95% − 85%) = $40,000 more line, with the same mortgage

Because the mortgage does not change, every 5 points of CLTV adds 5% of the value to the line. For this home:

Lenders count the whole line for this test, drawn or not; Fannie Mae's home-equity CLTV ratio, for example, includes the full amount of any HELOC.^[6] The HELOC LTV calculator shows the same math at ordinary limits.

The cushion: how far prices can fall

At 95% CLTV a 5% price drop wipes out your equity; at 80% the home can lose a fifth of its value first. The cushion is simply 100% minus the CLTV. A second, tighter threshold matters more for a line you have not finished drawing: Regulation Z lets the lender stop further draws or cut the limit if the home's value "declines significantly" below the appraisal.^[3]

The official commentary gives a test for "significantly": the gap between your available equity and the credit limit shrinks by half. Its example is a $100,000 home with a $50,000 first mortgage and a $30,000 line, which may be frozen if the value falls to $90,000.^[4] Applied to any CLTV, the drop that meets that test is half the cushion:

So a line opened at 95% CLTV can, under that test, be frozen after a 2.5% dip, while one opened at 80% can absorb 10%. The commentary also says the lender does not need a new appraisal before suspending the line.^[4] If you plan to draw the money over several years, a high-LTV line is the least dependable kind.

Why high-LTV lines cost more

Lenders price home equity credit partly on the combined LTV, so the same borrower usually pays more for a 95% line than an 85% one.^[2] Supervisors list higher loan-to-value and debt-to-income ratios, and interest-only features, among the things that raise risk in home equity lending, and expect lenders to check that you could repay the fully drawn line if rates rise.^[1] Expect stricter credit standards along with the higher rate.

Worked example

Using the calculator's defaults: a $400,000 home with a $300,000 mortgage and a $60,000 line.

1. CLTV = ($300,000 + $60,000) ÷ $400,000 = 90%. That is a high-LTV line by the supervisors' definition.
2. The lender's 95% limit would allow up to $80,000, so $60,000 fits with $20,000 to spare.
3. Cushion: 10%. A fall to $380,000 (−5%) halves the equity gap and meets the freeze test; a fall to $360,000 leaves no equity.
4. If you only need $40,000, an 85% line keeps a 15% cushion and, typically, better pricing.

Net cash: what reaches you after up-front costs

The line you are approved for is not the cash you can use: appraisal, application fees, points and closing costs come off the top, and points are charged on the credit limit, not on what you draw.^[5] Enter the lender's fee list and the estimate of third-party fees in the calculator's last field to see the net. Because a high-LTV line is often smaller in dollars than the costs of a cash-out refinance, a few thousand dollars of fees is a large share of it.

Questions to ask before you apply

Every question below has an answer in the disclosures federal rules require before you open a home equity plan, so you can compare high-LTV offers line by line:^[3]

• What does it cost to open and keep? The itemized list of the lender's fees and the estimate of third-party fees.
• How is the rate set, and how high can it go? The index, the margin, any periodic limits and the maximum rate, with the minimum payment on $10,000 at that maximum.
• When can the lender freeze, cut or end the line? The conditions are listed, or the lender must give them to you on request; at a high CLTV a small price drop can meet them.^[4]
• How long is the draw period, how is the minimum payment figured, and is there a balloon? The payment terms and the $10,000 example.
• Is there a minimum draw or minimum balance? Listed with the transaction requirements.

If the home is your principal dwelling, you also have three business days after opening to cancel the line.^[7]

Alternatives to a high LTV HELOC

• Borrow less. Draw only what the project needs; size it with the home improvement loan calculator.
• A fixed-rate loan. A home equity loan cannot be frozen once funded, because the money is paid out at closing.
• Wait for equity. Each principal payment raises the line you can get at a normal limit; the LTV calculator shows the pay-down needed.

If a lender does freeze or reduce your line, the CFPB's booklet suggests asking why and what would restore it, checking your credit reports, and shopping for another line.^[5]
