House Hacking Case Study

When Gianna first heard about house hacking from @thekeyresource, she was excited about the possibilities. Gianna has the goal of building long-term generational wealth. She decided to use house hacking as a strategy to help her pursue this goal.

Additionally, she knew that house hacking could help her pursue a career transition from teaching into tech.

The House Hack

Once Gianna heard about house hacking, she started researching potential properties through the MLS. After searching for a while, she settled on a mixed-use property with both a commercial and residential unit. Throughout her search, she only considered already occupied cash-flowing properties as potential options.

The property she decided on had air rights, a 10-year tax abatement, and a commercial tenant on a triple net lease. Plus, it didn't need any additional work.

The Tenants

Once she closed on the property in March 2020, Gianna used Facebook to find a roommate for her unit within two days. The commercial unit within the building came with a tenant in place.

The Numbers of the Deal

It’s time to find out exactly how profitable this house hacking strategy was!


Gianna used an FHA loan to purchase the $350,000 property with a 2.89% interest rate. With that, she put down $11,000. 

In total, Gianna's monthly mortgage is $1,920 which includes principal, interest, taxes, and insurance.

Rental Income

When Gianna bought the property, she was able to rent the commercial space and part of her unit for a combined total of $2,400 per month. 

  • Gross Rent: $2,400
  • Mortgage payment: $1,920
  • Cashflow before maintenance and vacancies: $480
  • Housing costs before house hacking: $800
  • Total housing savings: $1,280

The cash flow of the property is positive. With that, Gianna can live for free and has extra cashflow in her pocket every month. Currently, she is using the new income to build towards her generational wealth goals. With the benefits of imputed rents, tax-deductible mortgage interest, and capital gains tax savings, she is thrilled with her choice.
