A co-owner of my rental wants out: what are my options?
There are four routes: you buy their share, they sell their share to someone else, you sell the property together, or, if nothing else works, a court divides or sells it. Start by reading your agreement, then settle the value, the loan, the tax records and how the books close before you agree on anything.
Start with what you already signed
Read the operating agreement or co-ownership agreement for a buy-sell clause, a right of first refusal, a valuation method and notice periods. If it says how an owner exits, that is the route. If it is silent or there is no agreement, you are negotiating, and the rest of this post is the list of things to settle.
The four routes
| Route | How it works | What to watch |
|---|---|---|
| You buy their share | You pay an agreed price and take their ownership | The price, and where the cash comes from. The loan may need the lender's approval to change owners. |
| They sell to a third party | The leaving owner finds a buyer for their share | Your agreement may give you a first chance to buy, and you may not want the new partner. |
| Sell the property | Everyone sells and splits the proceeds | Taxes, costs of sale, and tenants in place; see selling with tenants. |
| Court-ordered sale or division | One owner asks a court to partition the property | Slow, public and costly; usually a last resort. |
Settling the price
Agree how the value will be set before debating the number. Options include a licensed appraisal paid for by both, a broker opinion, or an average of two appraisals, one chosen by each side. Then compute the departing owner's share from the value, not from what they originally paid in.
Example a made-up fourplex valued at $800,000 with a $480,000 loan, owned 50-50. Equity is $800,000 - $480,000 = $320,000. A 50 percent owner's share of the equity is $160,000. If the partners agree a $10,000 discount for selling costs the buyer saves, the buy-out is $150,000, and the remaining owner then holds 100 percent and the whole loan.
The example ignores taxes, which is where the departing owner's outcome can differ widely. Both sides should talk to their own tax preparer before signing.
The loan, the tenants and the books
- Loan: ask the lender whether a change of owners needs consent or a refinance. If the departing owner is on the loan personally, ask for a release in writing.
- Tenants: leases stay in force with the property. Tell tenants in writing if the contact for rent or repairs changes.
- Deposits and reserves: confirm where each tenant's security deposit sits and that the remaining owner takes responsibility for it.
- Insurance: update the named insureds and the entity on every policy.
- Bank accounts: remove the departing owner from signing authority and online access the day the deal closes.
- Books: close the departing owner's capital account at the closing date, with a final statement showing contributions, distributions and the buy-out payment.
Keep the signed buy-out, the final statement and the closing records for the period in IRS Publication 583, and give your tax preparer the closing date and amounts so the return reflects the change in owners.
If talks fail
A partition action asks a court to divide the property or order it sold. California's Code of Civil Procedure 872.210 lists who may bring one (text, as of October 2026); other states have their own rules and procedures. Because it is slow and expensive, many owners agree to mediation first. Ask a lawyer licensed in your state about timing and costs.
Where DoorKeeping fits
DoorKeeping keeps a ledger per property and per owner entity, so the final statement for a departing owner and the last month's bank-matched rent are already in one place. Removing a partner's access is one change on the team screen. DoorKeeping gives no legal or tax advice, and the price is $2 per unit per month.

Questions
- How do you value a co-owner's share of a rental?
- Value the property by appraisal or broker opinion, subtract the loan, and take the owner's percent of the equity. Adjust only for terms both sides agree to.
- Does the lender have to approve a buy-out?
- Often the loan has a due-on-transfer clause, so ask the lender before signing. Read the loan documents.
- Can a co-owner force a sale?
- In many states a co-owner can ask a court for partition. It is slow and costly, so most owners try an agreement or mediation first.
