How Montgomery County Recordation Charges Apply to a Rental HELOC

The Quick Read: On a rental HELOC, Montgomery County, Maryland, taxes the debt that the recorded deed of trust secures, not the value of the property. The rate is a per-$500 schedule, and the tax is generally paid before the lien is recorded. Owner-occupant breaks rarely help a rental, so plan for the full charge.

• The taxable amount is the maximum principal stated on the deed of trust, unless the borrower elects to pay only as money is drawn.
• Up to $500,000 of secured debt, the county’s published rate is $8.90 per $1,000, rounded up to the next $500.
• Bands above $500,000 add a premium layer, and the combined rate roughly doubles by $600,001.
• The $100,000 owner-occupied exemption is for a buyer’s principal residence, so a rental investor should not count on it.
• Recording fees paid to the court clerk are a separate, flat charge from the tax.

This article covers Montgomery County, Maryland only. Other states have a Montgomery County, and their rules differ. Maryland uses a state framework with county-set rates, which makes it a clean example of how a local tax on a recorded lien changes what an equity line costs.

What Is Taxed When a Rental HELOC Is Recorded?

A HELOC secures a stated maximum principal with a deed of trust, so it is a recordable document that carries recordation tax. The tax is measured on the debt secured, not on what the property is worth. Maryland’s tax-property statute applies the rate to each $500, or fraction of $500, of the principal amount of the debt secured, per Maryland General Assembly §12-103. The same statute lets each county’s governing body set its own rate.

A second-lien HELOC is its own new instrument. It is taxed on its own secured debt. Nothing in the sources suggests the tax already paid on a first mortgage covers it.

Two other charges get confused with this one. Transfer tax applies to a sale of the property, not to a security instrument like a deed of trust. The clerk’s recording fee is a flat charge for filing the document and is separate from the tax.

How Do Montgomery County Recordation Charges Add Up by Tier?

The county tax has three layers: a base, a school increment, and a premium that applies only to values above $500,000. The county’s own MC311 rate page lists $8.90 per $1,000, rounded up to the next $500 increment, up to $500,000. That equals $4.45 per $500.

Above $500,000, the premium layer steps up in bands. The combined totals below are those published in Seyfarth Shaw’s summary of the rate change, which followed Bill 17-23.

The county’s Council packet for Bill 17-23 supports the premium figures and identifies the state statute that creates the tax.

Whether the higher bands apply to the whole instrument or only to the slice above $500,000 is not settled in the published county materials. Ask the title agent how the clerk’s office computes it before you rely on either reading.

Pay on the Limit or Pay as You Draw?

Maryland lets the borrower choose how a credit line is taxed. Tax-Property §12-105 sets out two paths.

Pay on the limit. Tax is computed and paid once on the maximum principal stated to be secured. It does not matter what is actually advanced or readvanced. This path is simple, and no later filings are needed. The downside is that you pay on capacity you may never use.

Pay as you draw. Tax applies only to the principal incurred when the instrument is recorded. After each new advance, the borrower files a sworn statement of the added debt and pays tax on it. The statute allows seven days after the debt is incurred. If an advance repays earlier debt, no tax applies to that additional debt.

The statute also says a lender must tell a consumer borrower that either method is available, and that the borrower owes any later tax under the pay-as-you-draw path. Whether a rental-property line is treated as a consumer loan depends on how it is structured, so ask your lender which disclosure applies to your file.

Many lenders prefer the limit-based method because it avoids tracking later advances. Confirm what your lender permits before assuming you can choose.

On a rental line, the deferral is also small. On the investment equity lines we arrange, at least 75% of the line is drawn at closing. Paying as you draw can therefore postpone tax on at most the remaining quarter of the limit. A sworn filing and misdemeanor exposure for misstating the debt buy you a modest saving.

What Does the Arithmetic Look Like?

Run the numbers on a $250,000 line on a rental in the county. At $500 per increment, that is 500 increments. Multiply by the $4.45 base-plus-school rate and the tax on the full limit comes to $2,225. That figure is arithmetic from the county’s published rate, not a quote, and the clerk’s office controls the final number.

Rounding works against you at the edges. A line stated at $250,250 counts as 501 increments, because any fraction of $500 counts as a full one. Stating the limit at a round number can avoid paying on a sliver.

Pay on the limit and the draw does not matter. Elect to pay as you draw and the starting bill is lower, but each later advance adds tax and paperwork.

Do Exemptions Help a Rental Investor?

Rarely. Maryland’s exemptions mostly serve owner-occupants.

• The $100,000 owner-occupied exemption is for an individual buyer who intends to use the property as a principal residence. It does not apply to refinancing, second-home, or commercial transactions.
• The refinance exemption covers a refinance only up to the unpaid principal on the existing mortgage. The current statute text does not make clear whether it carries a principal-residence condition, so have a title professional check that point before you lean on it.
• A rental HELOC is new principal, not a replacement of an existing balance. Little or none of it fits refinance relief, and it brings no purchase-money exemption.

So the practical rule is to treat the full per-$500 charge as a cost of the line.

Where the General Rule Breaks

Increasing the line later. A supplemental instrument is not taxed except to the extent that consideration is payable or the unpaid principal debt is increased, per the state’s fiscal note on HB 1310. The principle is that you pay on the added debt, not twice on the old. Confirm it is still current with the clerk.

Lines that cross $500,000. An investment-property equity line on our network caps at $500,000 total, so a rental line never reaches the premium bands by itself. Larger lines are limited to primary residences. The premium tiers matter mainly for larger instruments, such as a bigger refinance.

Lender-paid or no-closing-cost lines. In our experience, offers to cover closing costs often carve out government recording charges. Ask whether the recordation tax is included.

Vesting. The sources do not say that LLC ownership changes the tax, so no tax effect should be assumed. As a program matter, investment equity lines require title held by the individual borrower or a revocable living trust. A property already deeded to an LLC would need a vesting change first, subject to program terms.

Property in more than one place. For real property located partly in Maryland, the statute applies the tax in the ratio of in-state value to total value.

Why Do Online Numbers Disagree?

Rates changed when Bill 17-23 took effect in October, and older figures still circulate. The county’s own MC311 page is a good example. Its under-$500,000 figure is current, but its description of the over-$500,000 tier predates the bill. Use the premium bands in the table above, and check the county code (Sec. 52-16B) or the clerk for the live schedule.

Rates also differ by jurisdiction. Baltimore City publishes a typical rate of $5 per $500, which is not Montgomery County’s rate. A figure from another county tells you nothing about this one.

What Does the Investor Decision Look Like?

Start with the facts about the equity line itself. On an investment property, the network’s ceiling is 70% CLTV, which is combined loan-to-value counting the first mortgage and the line together. Lines run up to $500,000 and need a credit profile of at least 700. Draws run on a 5-year interest-only period followed by a 25-year repayment period. Pricing and approval vary by file and lender, and every figure is subject to lender guidelines.

One availability point matters here. Lendmire arranges equity lines in 16 states, and Maryland is not one of them. So for a Montgomery County rental, the tax mechanics above apply to any lender’s line, but a DSCR cash-out refinance is the structure we can arrange there. Lendmire’s piece How Much Recordation Charges Add to a Rental HELOC by County compares how the charge changes from one county to the next. Lendmire’s piece Maryland Recordation Charges on a Rental HELOC for Out-of-State Owners covers the same charge for owners who live elsewhere.

A DSCR cash-out refinance works differently. DSCR means debt service coverage ratio, a test of whether the property’s rent covers its monthly payment of principal, interest, taxes, insurance, and any association dues. Across most of our network, cash-out tops out around 75% LTV on a standard rental, with about six months of seasoning as the common expectation. The coverage floor starts at 1.00 for select programs. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Credit floors begin at 620 in parts of the network, most programs want around 660, and 700 or better unlocks the strongest leverage tiers. Loans generally start around $100,000. The complete DSCR loans guide walks through the full picture.

Recordation tax on a refinance can fall only on debt above the old principal where the refinance exemption applies, per the Council packet. A HELOC is taxed on the new principal it secures. Whether a rental refinance fits that exemption is a question for the title agent.

DSCR also treats a HELOC differently. The coverage test compares rent to the housing payment on the DSCR loan only. Clearing 1.00 also does not mean positive cash flow, because repairs, vacancy, management, and utilities sit outside the calculation. An equity line payment generally sits outside the DSCR test but still comes out of your pocket each month.

Before closing on any Maryland line, ask these questions:

1. What maximum principal will the deed of trust state?

2. Does the lender permit the pay-as-you-draw election, or does it require paying on the limit?

3. Is the recordation tax included in any fee waiver, or billed separately?

4. How does the clerk apply the premium bands: to the whole amount or only the excess?

5. What is the clerk’s flat recording fee for this document?

Tax treatment of how you use the funds can depend on how the property is held; keep clear records and speak with a qualified tax professional before relying on any deduction.
