The short answer
- Budget for first month’s rent plus a security deposit at signing, before furniture. On a $1,400 apartment in a state that caps deposits at one month, that’s $2,800.
- Deposit caps are set by each US state. California and New York both cap most deposits at one month’s rent. In England, the cap is 5 weeks’ rent when annual rent is under £50,000, and a holding deposit is capped at 1 week.
- Many landlords want your gross income to be 40 times the monthly rent. That’s a screening habit, not a law, and it’s the same as HUD’s 30% of income affordability line.
- Renters insurance averaged $171 a year in the US (NAIC, 2022 data). Your landlord’s policy doesn’t cover your belongings.
- Buy the essentials in week one and everything else later. Save the move-in money before you sign, not after.
What you pay before you get the keys
First month’s rent is almost always due at signing or move-in. On top of that:
The security deposit. In the US, each state sets its own rules. Two examples:
| State | Deposit cap | Deadline to return it after move-out |
|---|---|---|
| California | 1 month’s rent (2 months for some small landlords) | 21 days, with an itemized statement |
| New York | 1 month’s rent | 14 days, with an itemized statement (units not rent stabilized or controlled) |

New York
Deposit cap1 month’s rent
Deadline to return it after move-out14 days, with an itemized statement (units not rent stabilized or controlled)
California’s one-month cap has applied to deposits collected since 1 July 2024. The exception: a landlord who is an individual (or an LLC owned by individuals) with no more than two rental properties and four units can still ask for two months. In New York, the one-month limit means a landlord can’t ask for a deposit and “last month’s rent” on top.
Check your own state’s rules with its attorney general or court self-help site before you pay anything.
Application fees and utility setup vary by city and provider. Ask each one for the exact amount in writing.
England. Since 1 May 2026, under the Renters’ Rights Act, most private tenancies are assured periodic tenancies. The rules at the start:
- Holding deposit: up to 1 week’s rent, to reserve the property while checks are done.
- Tenancy deposit: up to 5 weeks’ rent if the annual rent is under £50,000, 6 weeks if it’s £50,000 or more. It must be protected in a government-approved scheme within 30 days.
- Rent in advance: nothing before you sign the tenancy agreement, and at most one month’s rent between signing and the start date.
- Most other fees, such as viewing or setup fees, are banned under the Tenant Fees Act.
A UK example. Tom rents a flat at £1,100 a month. His weekly rent is £1,100 × 12 ÷ 52 = £253.85. The most he can be asked for as a holding deposit is £253.85, and the tenancy deposit cap is 5 × £253.85 = £1,269.23. With a month’s rent, he needs £2,369.23 at the start. Ask in writing how the holding deposit will be applied.
The 40x rule and the 30% rule
Many US landlords and property managers ask for a gross annual income of 40 times the monthly rent. It’s common practice, not law, and some accept a guarantor or co-signer instead.
The maths behind it is simple. Twelve months divided by 40 is 0.30, so the 40x rule means rent takes 30% of your gross income. That matches the line HUD uses: households paying more than 30% of income for housing, utilities included, are “cost burdened”; above 50%, “severely cost burdened”.
For Priya, who is looking at a $1,400 apartment: $1,400 × 40 = $56,000 a year. Check it the other way: $56,000 × 30% ÷ 12 = $1,400. If she earns $48,000, the rule points her to rent of about $1,200 ($48,000 ÷ 40).
The 30% line includes utilities, so add them before you decide what you can afford. It’s a rule of thumb, not a guarantee: in an expensive city many people pay more, and it squeezes everything else.
Renters insurance and utilities
Renters insurance. The CFPB puts it plainly: your landlord isn’t responsible for damage to your personal property. A renters policy pays to replace things that are stolen or damaged, and some policies cover the cost of living elsewhere if you can’t stay in the home. According to the NAIC, as reported by the Insurance Information Institute, the average US renters premium was $171 a year in 2022. Some leases require it, so check yours. In the UK, the equivalent is contents insurance.
Utilities, in order:
- Electricity and gas. Find out who supplies the building. Book the start date for the day you get the keys, and ask whether a deposit is required. In the UK, read the meters on move-in day and give the readings to the supplier, as Citizens Advice recommends.
- Internet. Order as soon as you sign: installation dates can be weeks away in some areas.
- Water. Often included in rent in apartment buildings; otherwise open an account. In England and Wales, households can’t choose their water company, but you do need to tell it you’ve moved in.
- UK only: register for council tax with your local council, and get a TV Licence if you watch live TV.

The essentials checklist
The classic mistake is buying everything in the first week. Buy what you use every day, live there for a month, then fill the gaps you actually notice.
- Renters or contents insurance active from move-in day
- Power on, meters photographed
- Mattress, duvet or comforter, pillow, two sets of sheets
- One frying pan, one saucepan, a cutting board, a good knife
- Plates, glasses and cutlery for two
- Toilet paper, soap, bath towels
- Dish soap, sponges, trash bags, all-purpose cleaner
- Light bulbs, power strip, flashlight
- Basic toolkit and first-aid kit

A first-month budget, worked out
Back to Priya: $1,400 rent, and a take-home pay of $3,700 a month. The amounts below are example assumptions; swap in your own bills and quotes.
| Line | First month |
|---|---|
| Rent | $1,400 |
| Electricity and gas (estimate) | $110 |
| Internet | $60 |
| Renters insurance | $15 |
| Phone | $45 |
| Groceries | $400 |
| Transport | $150 |
| Starter essentials | $500 |
| Buffer for surprises | $150 |
| Total | $2,830 |

That leaves $3,700 − $2,830 = $870. Put it aside from month one: it’s the start of your emergency fund, which you’ll want the day the laptop dies.
- Rent38 %$1,400
- Starter essentials13 %$500one-off, drops in month two
- Groceries11 %$400
- Utilities and internet5 %$170$110 + $60
- Transport4 %$150
- Buffer4 %$150
- Phone and insurance2 %$60$45 + $15
- Left to save23 %$870
The key point: the $2,800 for the deposit and first month doesn’t come out of this monthly budget. It has to be saved before you sign. At $870 a month, that’s a little over three months: 3 × $870 = $2,610, so month four finishes it.
From month two, the essentials line shrinks and that money can go to savings. For a budget that holds all year, the step-by-step method is in How to make a monthly budget.
Create a goal “First apartment” for $2,800 by March 31, and log $500 for starter essentials
Ready: a “First apartment” goal of $2,800 by March 31, and a $500 expense under “Housing”. Save them?
Each month, say “I put $870 in First apartment” and the progress bar moves. A monthly reminder to do it takes one sentence too.

How much money should I save before moving into my first apartment?
At least first month’s rent plus the security deposit, plus enough to buy essentials and cover one month of bills. On a $1,400 apartment with a one-month deposit, that’s $2,800 before anything else. In England, on £1,100 a month, it’s £2,369.23 with a full 5-week deposit.
Is the 40x rent rule a law?
No. It’s a screening habit many US landlords use: gross annual income of at least 40 times the monthly rent. It works out to rent at 30% of gross income, the same line HUD uses to define housing cost burden. Some landlords accept a co-signer or guarantor if you fall short.
Can a landlord ask for first and last month’s rent plus a deposit?
It depends where you live. In New York, the one-month limit means a landlord can’t take a deposit and last month’s rent on top. In England, the landlord can’t take rent before you sign and can take at most one month’s rent between signing and the start date. Elsewhere, check your state’s rules.
Do I really need renters insurance?
Your landlord’s insurance covers the building, not your belongings, and some leases require renters insurance. The US average was $171 a year in 2022, according to NAIC data. Compare coverage limits, not only the price.
In short
A first apartment starts with money saved before signing (first month’s rent and a deposit capped by state or national law), an honest affordability check (40x rent, or 30% of income with utilities), insurance and utilities booked for key day, and essentials bought in two waves.
First action: tonight, multiply the rent you’re aiming for by 40 and by 2. The first number is the income most landlords expect; the second is your savings goal.
