A mortgage journal entry records the property you bought as an asset and the loan you took out as a liability at closing, then splits every monthly payment into three parts: principal that reduces the loan balance, interest that becomes an expense, and any escrow held for taxes and insurance. Get those three splits right and your balance sheet stays accurate for the life of the loan. Get them wrong, and you either overstate expenses (by treating principal as a cost) or understate them (by ignoring accrued interest at period end).
What follows is the full sequence, from the entry you make on closing day through the one you make when you pay the loan off.
The Entry at Closing
On the closing date, your books need to reflect both the property you now own and the debt you now owe. Two things happen in one compound entry: you debit a property asset account for the purchase price, and you credit Mortgage Payable for the loan amount. The gap between them is your down payment, credited to Cash.
Buy a building for $300,000 with a $240,000 mortgage and $60,000 down, and the entry reads:
- Debit Property/Building $300,000
- Credit Mortgage Payable $240,000
- Credit Cash $60,000
Work through your settlement statement line by line before posting. Every dollar on that statement has to land in an account somewhere, and prorations from the seller can shift the cash figure.
Closing Costs and Loan Origination Fees
Closing costs don’t all go to the same place. Costs tied to acquiring the property itself (title insurance, legal fees, recording fees, surveys, transfer taxes) get added to the Property account. They increase your cost basis and, for a rental or business property, the amount you’ll eventually depreciate.1Internal Revenue Service. Publication 551 – Basis of Assets
Loan origination fees (points and similar charges) follow different rules. Under current accounting standards, debt issuance costs are not booked as a separate asset. They reduce the carrying amount of the mortgage liability, shown as a direct deduction from the face amount of the note, and are then amortized over the loan’s term using the effective interest method.
Tax treatment diverges from that. Points paid on a mortgage to buy your principal residence are generally deductible in full the year you pay them, provided the points are computed as a percentage of the loan, are shown on your settlement statement, and you provided funds at least equal to the points. Points paid on a refinance must be deducted ratably over the life of the new loan.2Internal Revenue Service. Topic No. 504, Home Mortgage Points Your books and your tax return will often show these fees differently as a result.
The Monthly Payment Entry
Every monthly payment has at least two moving parts, and often three. The full amount comes out of Cash. On the debit side, Interest Expense picks up the borrowing cost for the month, Mortgage Payable is debited for the principal reduction, and any escrow amount goes to an Escrow Asset account.
Take a $2,000 payment early in the loan’s life:
- Debit Interest Expense $1,200
- Debit Mortgage Payable $400
- Debit Escrow Asset $400
- Credit Cash $2,000
The principal portion is not an expense. It’s a liability reduction, so it stays on the balance sheet and never touches net income. Interest does the opposite: it hits the income statement. Confusing the two is the single most common mortgage bookkeeping mistake, and it leaves both your reported expenses and your outstanding loan balance wrong.
The split changes every month. Early in the loan, interest dominates because it’s calculated on a large outstanding balance. As the balance falls, more of each fixed payment goes to principal. Your lender’s amortization schedule shows the exact split payment by payment, and you should be reading from it rather than estimating.
How the Interest Portion Is Calculated
Interest for the month equals the annual rate divided by twelve, multiplied by the current principal balance. On a $240,000 loan at 6.5%, month one’s interest is ($240,000 × 0.065) / 12 = $1,300. If that payment cuts the balance by $217, next month’s interest is calculated on $239,783, and so on. Because the base keeps shrinking, you can’t shortcut this by dividing total interest evenly across payments.
Amortizing the Loan Fees Each Month
If you recorded origination fees as a reduction to the mortgage’s carrying amount, a separate monthly entry amortizes them. Debit Amortization Expense (or Interest Expense, depending on how your chart of accounts is set up) and credit Mortgage Payable, moving the liability closer to its face value over the life of the loan. This is in addition to the payment entry above.
Accruing Interest at Period End
If your books close on a date that doesn’t line up with a payment date, you owe an adjusting entry for the interest that has accrued but hasn’t been paid.
Say your payment is due the first of each month and you close the year on December 31. Roughly a month of interest has built up and won’t be paid until January 1. Debit Interest Expense and credit Accrued Interest Payable for that amount. When the January payment posts, the accrued liability reverses and the rest of the payment splits normally.
Skip this and both your expenses and your liabilities come in low for the period. It’s easy to overlook because the mortgage feels like it runs on autopilot, but for quarterly or monthly reporting the distortion adds up.
Escrow: How It Moves Through Your Books
The Escrow Asset account is a holding tank. Money flows in each month through your payment entry and flows out when the servicer pays your property tax bill or insurance premium. On disbursement, recognize the actual expense:
- Debit Property Tax Expense (or Insurance Expense) for the amount paid out
- Credit Escrow Asset for the same amount
The expense hits the income statement when the servicer pays the bill, not when you fund escrow each month. Until disbursement, the escrow balance is just an asset representing your money held on deposit.
The Annual Escrow Analysis
Servicers are required to run an annual escrow analysis comparing what they paid out against what you contributed.3Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts The result is a shortage, a surplus, or a match.
A shortage means the servicer paid out more than you put in; your monthly escrow deposit typically rises for the next twelve months to close the gap. A surplus of $50 or more must be refunded within 30 days of the analysis; smaller surpluses can be refunded or applied to next year.3Consumer Financial Protection Bureau. 12 CFR 1024.17 – Escrow Accounts When a refund check arrives, debit Cash and credit Escrow Asset to bring the balance back into line.
Depreciation on Business or Rental Property
If the property is a rental or is used in a trade or business, depreciation is a recurring entry that runs for decades alongside the mortgage. Each period, debit Depreciation Expense and credit Accumulated Depreciation, a contra-asset that reduces the property’s book value. Land is never depreciated. Only the building and improvements are.
The IRS requires residential rental property to be depreciated over 27.5 years and nonresidential real property over 39 years, both straight-line under the general depreciation system.4Internal Revenue Service. Publication 946 – How To Depreciate Property Pay $300,000 for a rental and allocate $50,000 to land, and your depreciable basis is $250,000. Annual straight-line depreciation on residential rental is about $9,091 ($250,000 ÷ 27.5), or roughly $758 a month.
The closing costs you capitalized at the top of this process feed into that number. Title insurance, legal fees, recording fees, and similar charges added to the property’s basis increase the amount you depreciate each year.1Internal Revenue Service. Publication 551 – Basis of Assets
Paying Off or Refinancing the Loan
When the mortgage is paid off, the remaining Mortgage Payable balance gets zeroed out. Debit Mortgage Payable for the remaining principal, debit Interest Expense for any final accrued interest, and credit Cash for the total payoff amount.
Prepayment Penalties and Payoff Differences
If a prepayment penalty is included in the payoff, debit it to a separate expense account rather than folding it into interest; it’s a cost of terminating the debt. If the total cash paid differs from the loan’s carrying amount (which reflects any unamortized loan fees), the difference is recognized as a gain or loss on extinguishment of debt on the income statement in the period you settle.
Refinancing
A refinance is two transactions in sequence. First, extinguish the old loan: debit Mortgage Payable (Old) to zero and credit Cash for the payoff. Any unamortized debt issuance costs from the old loan get written off immediately as a loss on extinguishment; they don’t carry over.
Then record the new loan the same way you recorded the original: credit Mortgage Payable (New) for the proceeds, capitalize any new property-related closing costs into the property basis, and reduce the new liability’s carrying amount by any new loan fees. Pull a fresh amortization schedule from the new lender to drive the monthly payment split going forward.
Personal Residence vs. Business Property
The full entry sequence above assumes you’re keeping formal books, which most homeowners don’t do for a personal residence. If the property is your home, what actually matters is tracking your cost basis (purchase price plus capitalized closing costs) for when you sell, and keeping records of the mortgage interest you paid for a possible Schedule A deduction. Your lender reports annual interest on Form 1098 if you paid $600 or more.5Internal Revenue Service. Instructions for Form 1098 – Mortgage Interest Statement A personal home is not depreciated.
For a rental or business property, everything above applies. The property sits on the balance sheet of the owning entity (often an LLC), depreciation runs monthly, escrow disbursements produce deductible expenses, and loan fees amortize over the term. Commercial loans are also more likely to carry prepayment penalties that need their own expense line if you pay off early.
