Co-ownership infrastructure for inherited real estate

The home they left you deserves more than a group chat.

When siblings inherit property together, things get complicated fast. Cottage is the shared platform that brings clarity, fairness, and order to a family asset, without losing the family in the process.

Before it happens. After it does.
Before the transfer

Mark and Leslie are 65.

They own several properties. They have a will. But they have no way to prepare their four children for what comes next. Who manages it. Who pays the bills. What happens when they can't agree. They've watched it tear apart other families. They don't want that to be their legacy.

After it does

Holly is 52.

Her mother passed eight months ago. She has two siblings in other states and a house no one knows what to do with. She's been handling everything, property taxes, insurance, a leaking gutter, with a group text and a spreadsheet no one updates. She's exhausted. Her relationships with her siblings are starting to fray.

Simple by design

Set up in 10 minutes.

1

Add your property

Enter the address. We pull the estimated value, tax history, and property details automatically.

2

Set ownership stakes

Enter each sibling's percentage, equal or unequal. Every expense splits from there without anyone doing math.

3

Invite your siblings

They get an invitation, create a free account, and see everything you've set up. Expenses, documents, open proposals. All of it, right away.

Everything you need

One place for the property.
One place for the family.

Short-Term Rental Income Splitting

Most families think they have two options: sell or keep. List on Airbnb or VRBO through Cottage and rental income goes straight to each sibling based on their ownership stake.

For Mark and Leslie

The greatest gift you can leave isn't the property. It's a plan.

Set up your properties on Cottage before the transfer. Document what you want to happen. Invite your kids to see it. Give them a running start instead of a standing argument.
