What Your CPA Needs From You Before You Sell a Rental
Most landlords hand their accountant a sale the same way they hand over everything else: after it happened. The settlement statement shows up in a folder in February, along with a 1099 and a note that says "sold the duplex." Then the CPA goes looking for the rest of the story.
The problem is that the rest of the story decides your tax bill. What you originally paid, what you've put into the building since, and what you've already depreciated are the numbers that turn a sale price into a taxable gain. If those records are thin, your accountant can only work with what's provable.
So the useful question isn't "what will my CPA do with this sale?" It's "what does my CPA need from me before the sale, so the number comes out right?"
The standing caveat: I'm a buyer, not a CPA or tax advisor. This is a general list of what accountants typically ask for, not advice on your return. Confirm every item with your own CPA — they may want more, or want it organized differently.
Why "before" matters
A lot of tax outcomes on a rental sale are set the moment you sign. The closing date picks the tax year. The structure — one lump sum, payments over time, or an exchange into another property — has to be decided going in. And some of those options have deadlines or third-party requirements that can't be added after the fact.
Your CPA can only help you weigh those choices if they can see roughly what the gain looks like. They can't see that without your records. That's the whole case for gathering early: the records are what let the advice happen while the decisions are still open.
1. Your original purchase records
Start with how you got the property. Your accountant will typically want:
The settlement statement from when you bought it. This shows the price and the closing costs, some of which may be added to your basis.
How you acquired it. Bought, inherited, received as a gift, or transferred from a partner or spouse — each can be treated very differently. An inherited property in particular often has a different starting basis than what the prior owner paid, and that difference can be large.
The split between land and building. Only the building portion gets depreciated. If that allocation was set years ago, your CPA will want to know how it was done.
2. Every capital improvement since
This is where long-held owners most often leave money on the table.
A new roof, a furnace replacement, new windows, a rewired unit, a kitchen redone between tenants — improvements like these generally get added to your basis rather than written off as ordinary repairs. A higher basis usually means a smaller taxable gain when you sell.
But only if you can show it. Your CPA will likely want:
Invoices or receipts for major work, with dates and amounts;
What the work was, in enough detail to tell an improvement from a repair;
Which unit or system it touched, if the building has more than one.
Your accountant decides which side of the repair-versus-improvement line each item falls on. An improvement you can't document is, for practical purposes, an improvement you didn't make.
3. Your depreciation history
If you've been filing returns on the rental, you've been taking depreciation — or you should have been. Either way, it matters at sale.
Depreciation lowers your basis each year you own the building. When you sell, the portion of your gain tied to that depreciation is typically handled differently from the rest, and on a property held a long time it can be a bigger number than owners expect. I've written about that separately in depreciation recapture — the tax surprise that catches sellers.
What your CPA needs here is simple to describe and sometimes hard to find:
Prior-year tax returns showing the rental schedule and the depreciation schedule;
Any changes in how depreciation was figured — a switch in accountants, a cost segregation study, an improvement placed in service mid-year;
Any year you didn't take it. This one is worth flagging early. Depreciation you were entitled to but didn't claim can still affect your basis, and your CPA will want to know about it before the sale rather than discover it during.
4. The current operating picture
Your CPA isn't only looking backward. To help you think about timing and structure, they'll want a sense of the year you're in:
Year-to-date rent collected and expenses paid, as actuals rather than estimates;
The current rent roll and security deposits held, since deposits get handled at closing;
Any other big income events this year — retirement, a spouse's job change, another property sale, a business sale.
That last item is the one that drives the closing-date question. The same sale can land very differently depending on what else is in the year. If your books aren't in shape to answer these quickly, getting your rent roll and books buyer-ready before you sell walks through how to clean them up — and the same work serves your buyer and your accountant at once.
5. The proposed deal terms
Before you sign, give your CPA what's actually on the table:
The offered price and proposed closing date;
The structure — all at closing, or some portion paid over time under a note;
Any seller credits, repair agreements, or prorations that will show up on the settlement statement;
Anything unusual — personal property included, a lease-back, a partial interest.
This is the step most sellers skip, and it's the one with the most leverage. If your accountant sees the terms while they're still terms, they can tell you whether a January close beats a December one, or whether spreading payments over several years changes your picture. For a closer look at that trade-off, see capital gains vs. installment sale: a side-by-side for a 2-4 unit.
6. After closing: the final settlement statement
Once the sale closes, your CPA will need the final settlement statement, any 1099-S issued, and mortgage payoff figures. If payments are coming to you over time, keep the signed note and a record of every payment received.
A simple way to start
Make one folder labeled with the property address. Put the purchase settlement statement and the last three years of returns in it first — those answer most early questions. List every major improvement you remember, with an approximate year, before you hunt for receipts. Then book an hour with your CPA this fall, folder in hand, and ask what's missing.
How I fit into this
I'm a local buyer here in York County. I buy 2-4 unit rentals directly from owners and hold them — I own and operate one myself, so the record-keeping side of this is something I live with too. Because I'm buying directly, the closing date and the structure are things we can actually talk about, which are exactly the levers your accountant is likely to ask about.
I'm not going to tell you what a sale does to your return; your CPA will. What I can do is give you a real number and real terms to bring to that meeting.
