House hacking — living in a property while renting part of it — is one of the most accessible ways into both homeownership and investing in high-cost California, because you can use FHA or VA owner-occupant financing instead of pricier investor loans. Here is how it works in the Simi Valley and Ventura County market.
What is house hacking?
House hacking means buying a property you live in while renting out part of it — so tenants help cover your mortgage. In high-cost California, it is one of the most accessible ways to get into both homeownership and real estate investing at the same time, because you can use owner-occupant financing instead of investor loans.
The two common forms are buying a small multifamily property (a duplex, triplex, or fourplex) and living in one unit, or buying a single-family home and renting out an ADU or spare rooms.
Why owner-occupant financing is the key advantage
The financing is what makes house hacking work. As an owner-occupant, you can access loan programs with far lower down payments and better terms than a pure investor would get.
- FHA loans: allow low down payments and can be used on 1–4 unit properties as long as you occupy one unit as your primary residence. See our FHA buyer guide for California for the details.
- VA loans: eligible veterans and service members can buy a 1–4 unit owner-occupied property, often with no down payment, subject to entitlement and occupancy rules.
- Occupancy requirement: these programs require you to live in the property (typically for at least the first year). They are not for buying a building you never intend to occupy.
- Counting rental income: lenders may let you count a portion of projected rent from the other units toward qualifying, which can help with the high purchase prices here.
Two ways to house hack in this market
1. Live in one unit of a small multifamily
Buy a duplex through fourplex with owner-occupant financing, live in one unit, and rent the rest. Small multifamily is genuinely scarce in Simi Valley and much of the Conejo Valley, so be patient and ready to move when the right property appears. See our Simi Valley investment property guide for how local supply shapes the search.
2. Rent an ADU or rooms in a single-family home
If small multifamily is hard to find, buy a single-family home and add or use an ADU, or rent spare bedrooms. California's statewide ADU laws make this a realistic path, and a permitted unit can offset a meaningful share of your housing payment. Our Simi Valley ADU guide walks through the local rules and costs.
How the math works here
In a high-cost market, house hacking rarely means living for free on day one — but it can dramatically lower your effective housing cost while you build equity and learn to be a landlord on a small scale.
- Your tenants' rent offsets part of your mortgage, taxes, and insurance, lowering your out-of-pocket housing cost.
- You build equity through appreciation and loan paydown on a property you would be paying for anyway.
- After you satisfy the occupancy period, you can potentially move on and keep the property as a full rental, then repeat.
- Model it conservatively: account for vacancy, maintenance, and the reality that AB 1482 may cap rent increases on your tenants.
Confirm loan eligibility with a lender and tax treatment with a CPA — owner-occupied investment property has its own rules.
Is house hacking right for you?
House hacking fits buyers who are comfortable sharing a property or living next to tenants, want to enter the market with less cash, and are willing to take on light landlord duties. It is a stepping stone many Ventura County investors use to build a portfolio over time. If that sounds like you, the next step is matching the strategy to what is actually available locally.
Frequently Asked Questions
Can I use an FHA loan to house hack a multifamily property?
Yes. FHA loans can be used on 1–4 unit properties as long as you occupy one of the units as your primary residence, typically for at least the first year. Lenders may also let you count a portion of projected rent from the other units toward qualifying. See our FHA buyer guide for California for the specifics and confirm current terms with a lender.
Is house hacking allowed with a VA loan?
Eligible veterans and active service members can use a VA loan to buy an owner-occupied 1–4 unit property, often with no down payment, subject to entitlement and occupancy requirements. As with FHA, you must live in one of the units. Confirm your eligibility and the current rules with a VA-savvy lender.
Can I house hack a single-family home in California?
Yes. If small multifamily is scarce, you can buy a single-family home and rent out an ADU or spare bedrooms. California's statewide ADU laws make adding or using an accessory unit a realistic path, and the rental income can offset a meaningful share of your housing payment. Confirm current local ADU rules for your city and lot.
Will I live for free if I house hack in Simi Valley?
Usually not on day one. In a high-cost market, tenant rent typically offsets part — not all — of your mortgage, taxes, and insurance. The real benefit is a much lower effective housing cost while you build equity through appreciation and loan paydown, with the option to keep the property as a full rental later.
