The question almost every new landlord asks is whether to hold the rental in an LLC. The pitch is clean: a lawsuit against the property stops at the LLC and never reaches your house, your savings, or your paycheck. That is the right idea, and for some portfolios it is worth every dollar. The mistake is treating the LLC as a default rather than a decision with a price tag, because the price tag runs for as long as you own the property.
This page does the math the incumbents skip. It puts the real 10-year cost of holding an LLC next to the actual equity you are protecting, and it tells you plainly where insurance does the same job for less. It also flags the one trap that bites people who already have a mortgage. None of this is legal advice. It is the framework I wish someone had handed me before I formed anything.
What an LLC actually does, and what it does not
An LLC is a legal wrapper. Held correctly, with the property deeded into the entity and its money kept separate from yours, it limits your liability to the assets inside the LLC. If a tenant or a visitor sues over something tied to that property and wins more than your insurance pays, the judgment reaches the LLC's assets, not your personal ones. That is the entire benefit, and it is a real one.
What an LLC does not do matters as much. It does not lower your taxes. It does not make you a better landlord. It does not protect you from your own negligence in every case, and it does nothing at all if you treat the account as a personal piggy bank, which is how courts pierce the veil. It also does not replace insurance. The lawsuit still gets defended by your policy first; the LLC only matters when a verdict exceeds your coverage.
The taxes: usually nothing changes
Here is the part that surprises people. A single-member LLC is, by default, a disregarded entity for federal tax purposes. The IRS looks straight through it. Your rents, your repairs, your depreciation, your mortgage interest: all of it still lands on Form 1040 Schedule E exactly as it would if you owned the property in your own name. You do not file a separate business return, and your 27.5-year depreciation schedule is unchanged.
A multi-member LLC is different. Two or more owners, and the entity files Form 1065 as a partnership and issues each member a Schedule K-1, which you then carry onto your personal return. That is more paperwork and usually a tax preparer's bill. If you are considering an LLC mainly for tax savings, stop: a single-member LLC gives you none, and the multi-member version adds cost. The reason to form one is liability, not taxes.
The figures here are general estimates to help you organize your thinking and your year for your CPA. They are not tax or legal advice. Single-member LLC guidance lives in the IRS guide to single-member LLCs; entity choice and any property transfer should be reviewed with a CPA and an attorney licensed in your state.
The 10-year cost almost nobody shows you
An LLC is not a one-time fee. It is a recurring carrying cost, and stacking 10 years of it is the only honest way to weigh it. State formation fees range widely, roughly $50 to $500 depending on where you file. The piece that adds up is the annual obligation: many states charge an annual report fee or a franchise tax, anywhere from nothing to several hundred dollars a year. Check your own state's figures; this is a national range, not a promise for your state.
Say you form an LLC for one property. A rough 10-year tally might look like this:
- Formation, one time: a midpoint of around $150 in state filing fees, plus an optional attorney or service fee if you do not file it yourself.
- Annual state fee, ten times: at, say, $100 a year, that is $1,000 over the decade. In a high-fee state it can be several times that.
- Registered agent, if you hire one: commonly around $100 to $150 a year, another $1,000 to $1,500 over ten years.
- Separate banking and bookkeeping: a dedicated bank account for the rental is required to keep the liability shield intact, and that adds a little friction every month.
Put the conservative pieces together and a single-property LLC can cost somewhere in the range of $2,000 to $4,000 over ten years before any unusual fees. Now hold that next to the question that actually decides it: how much equity are you protecting?
Cost versus the equity at stake
The LLC exists to shield your assets above what insurance pays. So the comparison is the 10-year cost against the exposed equity. Say you buy a duplex for $340,000 with $85,000 down, and after a few years you hold $120,000 of equity in it. A solid landlord policy with, say, $1,000,000 of liability coverage already defends and pays most claims. The LLC only earns its keep in the rare event a judgment blows past that policy limit and a creditor comes for the equity.
When the equity is small, early in the loan, the math often favors insurance: you are paying $2,000 to $4,000 over a decade to wall off an amount that good coverage would handle anyway. As the equity grows, and as you add properties, the LLC's value rises because there is more to lose and more lawsuits can touch you. Many self-managers carry strong insurance early and form entities once the equity and the door count justify the overhead. For the insurance side of this trade-off, the umbrella insurance versus LLC comparison runs the numbers on covering the gap with a policy instead.
The due-on-sale trap on a mortgaged property
This is the part that quietly costs people. If your property carries a mortgage and you deed it into an LLC, you are transferring title, and almost every mortgage contains a due-on-sale clause that lets the lender call the entire loan balance due on transfer. Lenders rarely act when payments keep coming, but rarely is not never, and you are relying on the lender's forbearance, not on a right.
People often cite the Garn-St Germain Act as protection. It does shield several kinds of transfers from due-on-sale enforcement, but it does not clearly cover a transfer into an LLC, and courts have not settled the question cleanly. Do not assume you are exempt. Before moving any mortgaged property, read the deeper walkthrough in putting a mortgaged rental into an LLC, then talk to your lender and an attorney. There is no reliable workaround to promise here, only a risk to weigh.
One LLC, several, or a series
If you do form entities and own more than one property, the next question is structure: one LLC holding everything, one LLC per property, or a series LLC. Each trades cost against how cleanly a lawsuit at one property is walled off from the others. That is its own decision with its own math, worked through in one LLC per property, a series LLC, or one LLC for everything. As you grow, fold this into how you build and protect a portfolio, because the right structure at three properties is not the right structure at ten.
Keep the records that prove it
An LLC only protects you if you respect it. That means the operating agreement on file, the deed in the entity's name, the EIN letter, and every annual report receipt kept where you can find them, plus banking and books that never mix with your personal money. The paperwork is what holds up when someone tries to argue the entity is a sham. Whether your duplex sits in an LLC or in your own name, the Schedule E tracking in rents.ai works the same, and a per-property documents area gives the operating agreement, deed, and EIN letter one home; it stores those files but does not draft the operating agreement or form the entity for you. The structure is a legal choice; the books are the proof that the choice was real.
