Grafton 2-Family with In-Law Suite: Turning Extra Space into Opportunity

Case Studies
family with in law suite

When we first toured this Grafton property in 2022, what struck us wasn’t just its size — nearly 5,000 square feet — but its untapped potential. On paper, it was listed as a two-family home with an in-law suite. In reality, it was a blank canvas. The bones were strong, the location was solid, and the in-law suite gave us an opportunity to create something more than just another duplex.

We purchased the property for $700,000, knowing that the real value wasn’t in what it was, but in what it could become.

The Vision

The question we asked ourselves was simple: how do we take an already big property and make it work harder? The answer was to turn it from two units into three by giving the in-law suite its own identity.

This strategy had several advantages:

  • More rental income streams to spread out risk.
  • Stronger property value by increasing usable, rentable space.
  • A path to house hacking — where rental income could cover most (if not all) of our living expenses.

Renovation Plan

Every unit needed a different level of attention. Instead of doing a blanket renovation across the whole property, we tailored the upgrades to each unit’s needs:

Secondary Unit (Cosmetic Updates)

Not every unit needs a gut job. This one got a lighter touch — fresh paint, new flooring, and small improvements that made it brighter and more appealing. Cost-effective, but enough to justify a healthy rent.

Main Unit (Full Gut Renovation)

This was the biggest project. We stripped it down, rebuilt the interior, and gave it a complete facelift. New kitchens, bathrooms, flooring, and systems. The result was a modern, highly desirable space that allowed us to raise the rent while keeping the tenant happy enough to stay.

In-Law Suite (Modernized & Updated)

This was the game-changer. What had been an underutilized side space became a fully independent apartment with its own entrance, updated finishes, and functional layout. Suddenly, we had a brand-new income stream without expanding the property.

By splitting the home into three income-generating units, we effectively turned one purchase into a small multi-family portfolio.

Living for Free: The House Hack Advantage

What makes this project even more rewarding is the way it changed our monthly finances. With all three units occupied, the combined rental income covers 100% of the property’s carrying costs. That means the mortgage, taxes, insurance, and upkeep are all paid for by the tenants — leaving us with virtually no out-of-pocket housing expense.

This is house hacking in its purest form: using real estate not just as an investment, but as a way to live more affordably while still building wealth. It’s a strategy that gives you breathing room every month, and at the same time, positions you to scale into future opportunities.

Lessons from Grafton

Looking back, this project reinforced a few key lessons that any investor or first-time buyer can take away:

  • Don’t overlook hidden space. An in-law suite, basement, or oversized layout might be the key to an extra rental unit.
  • Renovate with intention. Go all-in on units where you’ll see the biggest jump in rent or value, and keep other upgrades simple.
  • House hacking reduces risk. When tenants cover your living expenses, you’re free to grow without the stress of high monthly bills.
  • Cash flow and equity go hand in hand. Beyond living for free, this property gained $350,000 in equity in just a few years.


The Grafton project is proof that creativity and strategy can transform an ordinary property into a long-term wealth builder. By reimagining the layout, tailoring the renovations, and leaning into the house hack model, a standard two-family became a three-unit income property that pays for itself and grows in value year after year.
