Security Deposits: How Much, and How to Hold Them

The deposit is the least interesting part of renting a room and one of the most common sources of a bad ending. Almost all of that is preventable with decisions you make before anyone moves in.

Not legal advice. Deposit handling is governed by state and sometimes local law, and the requirements vary. Verify the specifics for where your property is — this is general practice, not a rulebook.

What a deposit is actually for

It covers damage beyond normal wear and tear, unpaid rent, and unpaid charges the lease provides for.

It is not a cleaning fee, not last month's rent, and not a general cushion for you. Treating it as any of those is how disputes start.

The wear-and-tear line matters. Carpet showing normal use, minor scuffs, faded paint — that's the cost of owning a rental, not a deduction. A hole in the wall, a broken door, damage from something that shouldn't have happened — that's different.

How much to collect

Most places set a maximum, and many operators simply collect a standard amount tied to the rent.

Things worth weighing:

Higher deposits reduce your applicant pool. Especially for room rentals, where people are often moving with limited cash. A deposit that's too large will slow your fill time.

Lower deposits leave you exposed on furnished spaces, where there's more of your property in the room.

Furnished spaces reasonably carry more. You're putting real assets in there.

Be consistent. Same standard for everyone. Varying deposits by applicant, based on a feeling, is the kind of inconsistency you don't want to have to explain.

Check what your state permits before setting your number, and write the amount into the lease.

Where the money goes

This is the part people handle casually and shouldn't.

Don't spend it. A deposit isn't income. It's someone else's money that you're holding, and you'll likely owe most or all of it back.

Keep it separate from operating funds. At minimum a separate account, so you're never in a position where you've spent a deposit you now have to return. Some jurisdictions have specific requirements about how deposits must be held — check yours.

Some places require notice to the resident about where the deposit is held. Find out whether yours does.

Track it per resident — amount, date received, and which lease it's attached to. Obvious with one resident, easy to lose track of with four.

What to document at move-in

This is the single highest-value twenty minutes in the whole process.

Photograph everything. Every wall, floor, fixture, appliance, and surface in their space and in shared areas. Timestamped. From angles you can replicate at move-out — this is the whole point.

Walk through it together and write it down. A simple condition checklist you both sign. Note existing scuffs, marks, and anything already damaged.

Have them acknowledge the condition in writing. A signed move-in inspection is worth more than any argument you could make later.

For furnished spaces, inventory it. What's in the room, condition of each item.

Store all of it somewhere you'll find it in two years. Not just on your phone.

The reason this matters: at move-out, a deduction is only as strong as your ability to show the condition changed. Without move-in documentation, you have your word against theirs, and that's a position you'll usually lose.

What to put in the lease

• The deposit amount and when it's due
• What it covers
• Where it's held, if required
• The condition the space must be returned in
• How and when it will be returned
• That a signed move-in inspection is part of the agreement

Clear terms up front prevent most disagreements later, because you're both working from the same document rather than from memory.

The house hack wrinkle

Two things are different when you live there.

Shared spaces are harder to attribute. Damage in a kitchen used by four people isn't obviously one person's. Document shared areas at every move-in and move-out, and be realistic about what you can fairly attribute.

The relationship makes it awkward. You'll be handling this with someone you've been living with. That's exactly why the documentation matters — it turns a judgment call into a comparison of two photographs.

The one-line version

Collect a consistent, lawful amount. Keep it separate and don't spend it. Photograph everything at move-in and get it signed.

Do those three and the return conversation — which is the next post — is almost always easy.
