DoorVault for House Hackers

Separate your personal living expenses from rental income without juggling multiple spreadsheets. DoorVault tracks each unit independently.

The Problem

Pain points house hackers know too well

Mixed Personal and Rental Expenses

When you live in one unit and rent the others, mortgage payments, insurance, and utilities are partially personal and partially business. Splitting these correctly for tax time is tedious and error prone.

Tax Reporting Confusion

Schedule E requires you to report only the rental portion of shared expenses. Most house hackers guess at the split or skip deductions they are entitled to because the math is too annoying.

No Tool Built for Your Situation

Property management software assumes you are a landlord with tenants in every unit. Personal finance apps do not understand rental income. Neither tool handles the hybrid scenario well.

The Solution

How DoorVault helps

Per Unit Tracking

DoorVault tracks each unit within a multi-unit property separately. Assign rental income and expenses to specific units while keeping shared costs at the property level.

AI Document Processing

Upload your mortgage statement, insurance declaration, or utility bill and DoorVault extracts the data automatically. No manual entry for recurring documents.

Transaction Categorization

Categorize each transaction as personal, rental, or shared. DoorVault keeps the separation clean so you are not guessing at tax time.

Cash Flow Dashboard

See your net position across all units. Track how much your tenants are covering of your total housing cost and monitor whether the house hack is working financially.

FAQ

Common questions

Can DoorVault handle a duplex where I live in one unit?

Yes. You create one property and track each unit separately. Rental income goes to the tenant occupied unit, shared expenses like the mortgage stay at the property level, and personal expenses can be excluded from rental reports.

Does DoorVault split shared expenses for Schedule E?

DoorVault tracks all expenses at the property and unit level. You categorize which are rental, personal, or shared. At tax time, your accountant can use the exported data to calculate the correct rental portion based on square footage or unit count.

What if I move out and rent all units later?

When you convert your unit to a rental, just start tracking it the same way you track the other units. DoorVault does not lock you into a house hacking setup. The property and all its history stays intact.

Can I track utilities separately for each unit?

Yes. You can add utility transactions and assign them to specific units or keep them at the property level if they are shared. DoorVault supports both configurations.
