Two tools for two chapters
One for the decision, one for the day-to-day. Subscribe to either on its own, or get both together with Household Pro — start wherever your family is right now.
Housing Financial Planner
Figure out whether combining households actually works on paper — before anyone signs anything.
- Model selling multiple homes and buying one together
- Compare properties side by side
- Project rental or STR income from an ADU or extra unit
- Layer in what each family member can contribute
- Export a clean summary PDF for lender meetings
Family Expense Manager
Once everyone’s under one roof, keep shared costs fair, clear, and drama-free.
- Track shared household expenses in one place
- Set custom contribution splits that fit your family
- See at a glance who’s contributed what
- Send gentle bill and contribution reminders
- Export your shared expenses to CSV any time
How it works
From “could this even work?” to a home that runs smoothly — in three steps.
Model the move
Enter your homes, the property you’re eyeing, and what each person can chip in. Patrimonio does the math.
Build the case
See the real monthly picture, debt-to-income, and rental income. Export a summary to share with your partner or lender.
Manage together
Once you’ve combined, switch on the expense manager to keep contributions fair and everyone in the loop.
Everything you need to decide — and to live it
Powerful enough for the numbers, gentle enough for the whole family to use.
Unlimited scenarios
Build one on the free trial. Subscribe to put “sell both and buy a duplex” beside “add an ADU” beside “rent instead” and compare them properly.
Rental & STR income
Add an accessory unit or short-term rental and see how the income changes what you can afford.
Fair contribution splits
Every family is different. Set the split that feels right or equal, by income, or fully custom.
Shareable summary PDF
A warm, readable document for the family conversation or a mortgage broker meeting.
Contribution dashboards
A clear view of who owes what this month, simple enough for every generation to read.
Bill & contribution reminders
Gentle email nudges before a shared bill is due or a monthly contribution is expected, so nothing slips.
Made for every generation at the table
The adult child running the numbers. The partner who just wants the bottom line. The parent who needs to see “here’s what I owe this month” in big, clear type. Patrimonio meets each of them where they are.
- Large touch targets and readable type — designed for older eyes
- Simple summaries for the family member who just wants the total
- Shareable plan links so everyone sees the same picture
- Works beautifully on a phone
