My First House Hack: What I Wish I Knew Before Buying

When I decided to try house hacking for the first time, I thought the strategy was pretty simple: buy a property, live in one part of it, rent out the other space, and let the rental income help cover the mortgage.

On paper, it made perfect sense.

In reality, there was a lot more to think about than I expected.

The biggest lesson was that the property isn't just a home — it's also a business.

Here are a few things I wish I had understood before buying:

1. Don't focus only on the mortgage payment

I initially looked at whether the rent could cover most of the mortgage. But there are plenty of other expenses: property taxes, insurance, utilities, maintenance, vacancies, repairs, and unexpected problems.

A deal that looks great based only on mortgage vs. rent can look very different once you include everything.

2. Tenant quality matters more than maximizing rent

It's tempting to choose the tenant willing to pay the highest rent. But when you live in the same property, having a reliable and respectful tenant can be much more valuable.

You have to consider how well someone fits with your living situation, not just their income and credit score.

3. Privacy is a bigger consideration than I expected

Living next to or above your tenants sounds easy until you realize you're sharing the same property every day.

Separate entrances, bathrooms, parking, laundry, and outdoor spaces can make a huge difference.

4. Have cash reserves

I didn't want to spend all my available cash on the down payment and closing costs.

Things break. Tenants move out. Repairs happen at inconvenient times.

Having several months of expenses available makes house hacking much less stressful.

5. Think about the exit strategy

Before buying, I think it's important to ask:

• Would I want to keep this property as a rental if I moved out?

• Would it appeal to future tenants?

• Does the neighborhood have strong rental demand?

• Will the numbers still work if I stop living there?

A house hack shouldn't only work while you're living in it.

Overall, house hacking can be a great way to reduce your housing costs while getting started in real estate investing. But the best deal isn't necessarily the property with the highest potential rent.

It's the property that works financially and fits your lifestyle.

For those who have already house hacked, what's one thing you wish you knew before buying your first property?
