Key takeaways
- Minimum down payment: as low as 3% of the purchase price
- Typical credit score needed: 620 or higher
- Private mortgage insurance (PMI) required if down payment is under 20%
- Debt‑to‑income (DTI) ratio should stay at or below 45%
- New Jersey transactions usually involve an attorney at closing
Conventional loans are the most common type of mortgage for buyers who have a solid credit profile and can put some cash down. Unlike government‑backed loans, they are not insured by the FHA, VA, or USDA, so the lender sets the qualification standards.
Key qualification factors
- Down payment: Conventional loans can be approved with as little as 3% down, but putting down less than 20% triggers private mortgage insurance (PMI), which adds to your monthly payment.
- Credit score: Most lenders look for a score of 620 or higher. Higher scores typically secure better interest rates and lower fees.
- Debt‑to‑income (DTI) ratio: Your total monthly debt payments—including the projected mortgage—should not exceed about 45% of your gross monthly income. Some lenders may allow a slightly higher DTI if other factors are strong.
- Loan limits: Conventional loan amounts in New Jersey follow the Federal Housing Finance Agency’s conforming‑loan limit, which is roughly $750,000 for most counties, with higher caps in a few high‑cost areas. The limit is adjusted each year.
New Jersey‑specific considerations
- Many home purchases are closed with a real‑estate attorney rather than a title‑company, which can affect closing costs and timing.
- The New Jersey Housing and Mortgage Finance Agency (NJHMFA) offers down‑payment assistance programs that can be paired with a conventional loan, provided the loan meets the agency’s eligibility criteria.
- Property taxes in New Jersey are among the highest in the nation, so budgeting for annual tax payments is essential when calculating your total housing cost.
When you apply, the lender will verify your income, employment, assets, and credit history. They’ll also order an appraisal to confirm the home’s value meets or exceeds the loan amount. If everything checks out, you’ll receive a loan estimate that outlines the interest rate, estimated monthly payment, and all closing costs.

FAQ
What is the main difference between a conventional loan and an FHA loan?
A conventional loan is not insured or guaranteed by the federal government, so lenders set their own credit, down‑payment, and DTI requirements. An FHA loan is backed by the Federal Housing Administration, allowing lower credit scores and as little as 3.5% down, but it requires mortgage insurance premiums for the life of the loan.
How does private mortgage insurance (PMI) work with a low down payment?
If you put down less than 20% on a conventional loan, the lender will require PMI to protect themselves against default. PMI is paid monthly and typically ends once you reach 20% equity, either through payments or home‑value appreciation, after which you can request cancellation.
Can I use New Jersey’s down‑payment assistance programs with a conventional loan?
Yes, many NJHMFA assistance programs allow you to combine a conventional loan with a grant or low‑interest loan for the down payment, as long as you meet the program’s income, purchase‑price, and first‑time‑buyer criteria.
Why does New Jersey usually require an attorney at closing?
New Jersey law mandates that a licensed attorney represent at least one party in a real‑estate transaction. The attorney reviews the deed, title report, and loan documents, ensuring the transfer complies with state regulations and protecting the buyer’s interests.
What steps can I take to improve my credit score before applying for a conventional loan?
Pay down revolving balances, avoid opening new credit lines, correct any errors on your credit report, and make all existing payments on time for at least six months. These actions can raise your score and improve the loan terms you qualify for.
