Ways to Reduce Costs

If your estimated new home price is exceeding your intended budget, here are some areas where you may be able to scale back expenses:

  • Opt for a smaller home size and simpler layout
  • Choose standardized or stock plans rather than 100% custom designs
  • Limit extravagant finishes and opt for mid-range options
  • Build a single story rather than multi-level home
  • Look for smaller or narrower lot sizes to reduce land purchase price
  • Use a reputable but affordable contractor
  • Complete some DIY work like painting or landscaping
  • Stage furnishings over time or repurpose existing pieces
  • Get multiple quotes from subcontractors and suppliers

Compromising on size or certain luxuries can potentially save tens of thousands. But avoid compromising on structural elements that impact safety and livability.

Is Buying an Existing Home More Affordable?

With the high price tag of new construction in New Jersey, you may be wondering if purchasing an existing home is significantly more affordable.

The median sales price for an existing single-family home in New Jersey is around $350,000 compared to $376,000 for new construction. However, there are additional factors to weigh when choosing between new vs. existing:

Benefits of Buying Existing

  • Lower upfront purchase price in most cases
  • Faster to move in, no lengthy construction
  • Landscaping and yards are established

Benefits of Building New

  • Everything is brand new and warrantied
  • Customise to your layout, finishes, style
  • Latest in energy efficiency and technology
  • No immediate repairs or renovations needed

While buying an existing home tends to have lower upfront costs and faster turnaround time, building new allows you to get a home tailored exactly to your needs and preferences without the need for any renovations. And in some markets, existing home prices are on par with new construction.

Timeline for Completion

Another major factor to consider is the project timeline. Building a fully custom new home in New Jersey takes an average of 6 to 16 months from breaking ground to getting the certificate of occupancy.

Elements impacting the schedule include permitting timeframes, construction start date, house size, weather delays, contractor availability, and customization level. Make sure to account for construction financing if needed.

Here is an approximate timeline:

  • Planning and design: 2 to 6 months
  • Permit approval: 1 to 3 months
  • Site work: 1 to 2 months
  • Foundation: 1 to 2 months
  • Framing: 1 to 2 months
  • Systems rough-in: 1 to 3 months
  • Interior finish: 2 to 4 months
  • Landscaping: 1 to 2 months
  • Final inspections: 1 to 2 weeks

Payment Options for Building a New House

  • Construction Loans: These are short-term loans used to cover the cost of building a new home. They typically have higher interest rates than traditional mortgages and are converted into a permanent mortgage once construction is complete.
  • Mortgage Loans: A traditional mortgage can be used if you’re buying a newly constructed home from a builder who is financing the construction. In this case, the mortgage process is similar to buying an existing home.
  • Owner-Builder Loans: If you plan to act as your own general contractor, an owner-builder loan can be an option. These loans require detailed construction plans and a proven track record of construction experience.
  • Home Equity Line of Credit (HELOC): If you already own a property, a HELOC allows you to borrow against the equity in your current home to finance the construction of a new one.
  • Personal Savings: Using personal savings to fund construction is another option, though it may require a significant amount of capital upfront.
  • Government Loans: Some government programs, like FHA construction loans, offer options for financing home construction with lower down payments and less stringent credit requirements.
  • Land Loans: If you need to purchase land for your new home, a land loan can be used for this purpose. It’s often combined with a construction loan for the building process.
  • Bridge Loans: These are short-term loans that can help cover the gap between the costs of building your new home and your future income or financial situation.
  • Investor Financing: For larger projects or developments, some builders may seek financing from investment groups or private investors.
  • Crowdfunding: A less traditional method, crowdfunding can be an option for those with a strong social network willing to contribute to their home-building project.

Building vs. Buying Which is The Best

Building a home offers the advantage of customization, allowing you to design a space that perfectly suits your preferences and lifestyle. It also ensures modern construction with potentially higher energy efficiency. However, building is typically more expensive and time-consuming than buying, with costs and project duration often unpredictable due to factors like material prices and construction delays.

Buying an existing home, on the other hand, is generally quicker and more cost-effective. It allows for immediate occupancy and often comes with established amenities like landscaping and neighbourhood connections. However, it might involve compromises on design and potential renovation costs to update or personalise the space according to your tastes and needs.


Building a new home in New Jersey comes at a significant cost, with the typical price range spanning $300,000 to $460,000 and pricing averaging around $376,000 for a single family house as of 2024. Exact budgets can vary dramatically depending on the size and design of your home, finishes and features included, lot specifications, contractor rates, and geographic region where you want to build. Carefully estimating costs during the planning stages and trimming expenses where reasonable can help keep your custom build within your budget. While constructing a new home is a large investment, the long term benefits of getting a personalised home that matches your lifestyle makes it worthwhile for many New Jersey homeowners.
