How Much Money Do You Need to Buy a House in New Jersey?
The short answer
You need cash for three things: the down payment, closing costs, and the out-of-pocket costs before closing, such as your deposit and inspections. Down payment minimums range from zero for eligible VA and USDA loans, to 3% for some conventional loans and 3.5% for FHA, to 20% if you want to avoid private mortgage insurance on a conventional loan. Your lender's Loan Estimate is where your real number comes from, and New Jersey's NJHMFA programs can help eligible buyers with the down payment and closing costs.
Most people ask "how much house can I afford?" The question that actually decides whether you can buy is a different one: how much cash do I need, and when? Here's how to put that number together for a home in New Jersey — without guessing.
What do I need cash for?
Three buckets:
| Bucket | What's in it | When you pay |
|---|---|---|
| Down payment | Your share of the purchase price | At closing (your deposit counts toward it) |
| Closing costs | Lender fees, title insurance, attorney, recording, prepaid taxes and insurance | At closing |
| Before-closing costs | Your contract deposit, home inspection, well and septic tests, radon, appraisal fee | Between signing and closing |
Many first-time buyers plan for the first bucket and get surprised by the other two. Plan for all three, plus a cushion for after you move in.
How much is the down payment?
It depends on the loan. Here are the common minimums, from each program's own materials:
| Loan type | Minimum down payment | Worth knowing |
|---|---|---|
| VA loan | Often none, if the price doesn't exceed the appraised value | For eligible veterans and service members. A one-time funding fee may apply. |
| USDA guaranteed loan | None — 100% financing | Primary residence in an eligible rural area; household income up to 115% of the area median. Much of Sussex and Warren County is rural, but eligibility is by address. |
| Conventional — Fannie Mae HomeReady | As little as 3% | One-unit primary residence, up to 97% loan-to-value; income limits apply |
| FHA loan | As low as 3.5% | Insured by the Federal Housing Administration; ask your lender about the mortgage insurance cost |
| Conventional, no mortgage insurance | Usually 20% | Below 20% down, a conventional loan usually requires private mortgage insurance |
So 20% isn't a requirement. It's the point where a conventional loan usually stops requiring private mortgage insurance (PMI). Whether it's worth waiting to save 20% depends on your situation — your lender can show you the monthly difference.
How much are closing costs?
They vary with the price, the loan and the property. In New Jersey, buyers typically pay lender fees, title insurance, a survey, their attorney, recording fees, and prepaid escrows for property taxes and homeowner's insurance. I've broken those down line by line in what closing costs buyers pay in New Jersey.
The good news: you don't have to guess. Your lender must give you a Loan Estimate within three business days of your application. It shows the projected payment and the estimated cash to close. Get one early, even before you're seriously shopping.
What will I pay before closing?
These come out of pocket during the contract period:
- Initial deposit when the contract is signed (it's credited toward your purchase at closing)
- Home inspection
- Private well water test, if the home has a well — the test is a condition of the sale in New Jersey; your contract will say who orders and pays for it (well guide)
- Septic inspection, for homes not on public sewer
- Radon test and oil tank sweep, where relevant
- Appraisal fee, often paid up front to the lender
The well, septic and oil tank items come up a lot in Sussex and Warren County, so budget for them separately. Get quotes from local inspectors rather than relying on national averages.
Is there help with the down payment in New Jersey?
Yes, for eligible buyers. The New Jersey Housing and Mortgage Finance Agency (NJHMFA) offers Down Payment Assistance alongside its first mortgage programs. According to NJHMFA's fact sheet updated June 17, 2026:
- DPA is a zero-interest, forgivable loan with no monthly payments — $10,000 in Sussex and Warren counties.
- It's forgiven if you live in the home as your principal residence for five years.
- It's paired with an NJHMFA first mortgage through a participating lender.
- First-time buyer means you haven't had an ownership interest in your primary residence in the past three years.
- Eligible homes include single-family homes, condos, townhomes, and two- to four-family homes where you live in one unit.
- You must move in within 60 days of closing.
- Income, purchase price, credit and debt-to-income requirements apply.
Program amounts and limits change, so check the current fact sheet with your lender. My first-time buyer guide for Sussex and Warren County covers the programs in more detail.
You can also negotiate a seller credit toward your closing costs in the contract. Loan programs limit how much, so ask your lender before you write the offer.
How much should I keep after closing?
Don't empty your accounts to close. Some lenders require reserves — a few months of mortgage payments left in the bank — and even when they don't, you'll want a cushion. In the first year in a North Jersey home, common surprises include:
- A heating-oil or propane fill-up right after you move in
- Septic pumping, water treatment service or a well pump repair
- Moving costs, utility deposits and basic tools
- Something the inspection didn't catch

Frequently asked questions
What is the minimum down payment to buy a house in NJ?
It depends on the loan. Eligible veterans can often buy with no down payment through a VA loan, USDA guaranteed loans offer 100% financing in eligible rural areas, Fannie Mae's HomeReady allows as little as 3% down, and FHA loans can go as low as 3.5% down.
Do I need 20% down to buy a house?
No. Twenty percent is the point at which a conventional loan usually no longer requires private mortgage insurance, not a minimum. Many buyers put down much less and pay mortgage insurance.
Is there down payment help in New Jersey?
Yes, for eligible buyers. NJHMFA's Down Payment Assistance is a zero-interest, forgivable second loan — up to $10,000 in Sussex and Warren counties as of its June 2026 fact sheet — that must be paired with an NJHMFA first mortgage. Income and purchase price limits apply.
How do I find out exactly how much cash I'll need?
Apply with a lender. They must give you a Loan Estimate within three business days of your application, showing the projected payment and the cash needed to close.
What do I pay before closing?
Usually your initial deposit when the contract is signed, plus inspections and sometimes an appraisal fee. Ask your lender and attorney which costs come out of pocket early and which are credited at closing.
