Your Closing Disclosure has about forty line items on it. Roughly six of them are named in a way that tells you what they are. The rest sound like they were generated by a committee that was paid by the syllable.

And every one of them has to go somewhere on your tax return.

The good news: there are only three places they can go. Sort them right in year one and your depreciation schedule is correct for the next 27.5 years. Sort them wrong and you either inflate your basis — which the IRS will happily correct for you at sale, with interest — or you quietly leave real deductions sitting on the table.

I've now done this on every property I own. The first time took me a weekend and a phone call I was embarrassed to make. I don't sort these by hand anymore — but I had to learn it by hand first, and that's the part worth passing along. Here's the framework, plus the four places I've watched people (myself included) get it wrong.

1. Three buckets. That's the whole system.

Every dollar on that statement is one of three things:

A. You paid it to own the building → capitalized into basis, split between land and building, depreciated.

B. You paid it to borrow the money → amortized in equal slices over the life of the loan.

C. You paid it to operate the place this year → deducted now, on Schedule E.

That's it. There is no fourth bucket, no matter how badly a line item wants there to be one.

And here's the part that trips everyone: the name on the CD does not tell you which bucket it's in. "Title insurance" appears twice on your statement and the two copies go to different places. What matters is not what the line is called. It's what the money bought you.

2. Bucket A — costs of acquiring the building

If it exists because you were buying a building, it lives here:

• Owner's title insurance policy
• Title search and abstract fees
• Escrow / settlement / closing agent fee (the purchase side)
• Recording fee for the deed
• Transfer taxes and documentary stamps, your share
• Survey
• Attorney fees for the purchase
• Broker or finder's fees you paid
• Any seller obligation you agreed to cover — back taxes, unpaid assessments, a lien payoff

None of this gets deducted this year. It goes into the same pot as the purchase price and depreciates alongside the building, at the thrilling pace of 1/27.5th per year.

Where people go wrong: deducting the escrow fee and title insurance in year one because they feel like services you paid for. They aren't. You bought a building. These were the toll booths on the way there.

3. Bucket B — costs of getting the loan

If it exists because you were getting a mortgage rather than a building, it goes here:

• Loan origination fee
• Points / discount points
• Application, underwriting, and processing fees
• Credit report fee
• Mortgage broker fee
• Lender's title insurance policy (this is the second copy — different bucket than the owner's policy)
• Recording fee for the mortgage or deed of trust (also the second copy)
• Loan document preparation

Straight-line over the term of the loan. A $6,000 origination fee on a 30-year note is $200 a year for thirty years. It is not going to change your life. It is, however, yours, and $200 a year for thirty years is a nice dinner annually until 2056.

The most common error on this entire forum: deducting points in full in year one. That treatment is real — for the mortgage on your primary residence. It does not follow you to a rental. Every spring someone posts a version of "my software let me deduct the points, so it must be fine," and every spring someone with credentials has to explain that tax software is a very confident intern.

The one honest judgment call: the lender-required appraisal. The acquisition rules list appraisals as costs that facilitate buying property, which says Bucket A. But it only exists because a lender demanded it, which says Bucket B. Practitioners genuinely split on this one. Pick a position, apply it to every property you own, and let your CPA tell you which side they'd rather defend. The dollars are small. The inconsistency across a portfolio is what turns a twenty-minute question into a weekend.

4. Bucket C — deducted this year

The short and pleasant list:

• Prorated property taxes for your period of ownership
• Per diem interest charged at closing
• Prepaid insurance, deducted over the period it covers
• Prorated HOA dues

And two impostors that look like Bucket C and are not:

Escrow funding is not a deduction. The two months of taxes and insurance your lender made you deposit is still your money — it's just sitting in someone else's account, being useful to someone else. You deduct it when the escrow agent actually pays the county and the insurer, which may well be a different tax year. Writing off the whole impound deposit at closing is the single most enthusiastic mistake in this category.

A transferred security deposit is not income. It arrived in your account, so it feels like income. It is a liability you inherited. It sits on your balance sheet doing nothing until you either hand it back or apply it to damage. Booking it as rental income in year one means you paid tax on money that was never yours — and then you'll get to feel great about it again when you return it.

5. The land allocation nobody does

Here's the step that gets skipped, and it's the expensive one.

Everything in Bucket A gets stacked onto your purchase price. Then the entire pile gets split between land and building on the same ratio.

Land doesn't depreciate. Ever. It just sits there, appreciating silently and giving you nothing at tax time. So if your property is 25% land, then 25% of your title insurance, your transfer tax, and your survey is parked in a bucket that will never produce a single dollar of deduction.

Three defensible ways to set the ratio:

1. The county assessor's land/improvement split for your purchase year, applied as a percentage to what you actually paid. Most common, easiest to document.
2. The site value line on a full appraisal.
3. A cost segregation study, which does this and considerably more.

The IRS doesn't mandate a method. It asks that yours be reasonable and consistent. Which sounds easy, and is — right up until year five, when someone asks how you arrived at 75/25 and you discover the assessor's website only displays current-year values and your original numbers are gone.

Which brings me to the actually important section.

6. What happens when you refinance

You've still got unamortized loan costs on the books from the original mortgage. When that loan gets paid off, the remaining balance generally becomes deductible in the year of payoff. Same at sale.

One wrinkle worth raising with your CPA before you assume the deduction: refinancing with the same lender. There's authority treating that as a modification of existing debt rather than a true payoff — which would mean you keep amortizing on the old schedule instead of taking the deduction. A different lender is the cleaner fact pattern. Not a reason to choose a lender, but a reason to ask the question before you count the money.

7. The two documents that save you a weekend

This part has nothing to do with tax law and it's the section that actually costs people money.

One: save the Closing Disclosure as an actual file, named with the property address. Not "somewhere in the closing packet." Not "in that email from the title company." A file. In a folder. With a name.

Two: screenshot the county assessor's land and improvement values the week you close. That page gets overwritten every year. The month you buy is the only easy moment to capture it, and it is the entire evidentiary foundation of your depreciation schedule.

I learned this the way most people learn things, which is expensively. Four years into owning a property, my CPA asked how I'd arrived at the land split. I did not know. I had not written it down. I spent a Saturday on the phone with a county office and a Sunday reconstructing an answer I'm still not fully in love with.

Two minutes at closing, or a weekend in year four. Those are genuinely the only two options on the menu.

The short version

Bucket A is what you paid to own it. Bucket B is what you paid to borrow. Bucket C is what you paid to run it this year. Split Bucket A against land. Save the two documents. Go do something else.

If anyone wants to post a sanitized CD with the ambiguous lines, I'm happy to walk through them here — the same four or five items confuse everybody, and it's more useful in public than in DMs.

Usual disclaimer: I'm an investor, not a CPA. This is how I think about my own books, not advice for your situation. The people on this forum with letters after their names are the ones to check with before you file — and several of them are better at this than I am.
