Paying For The Addition: A New Hampshire Homeowner’s Starting Point
Have you worked out roughly what you want built, and now you are staring at the question of how to actually pay for it?
Or are you trying to figure out how much to borrow when nobody has given you a number you trust yet?
In this post, you’ll learn how homeowners around here typically fund an addition, what additions actually cost in our range, how we get you to a figure solid enough to take to a lender, and where the number can still move once you have one.
How Do Homeowners Pay For A Home Addition In New Hampshire?
Most homeowners in New Hampshire pay for an addition with home equity, either a loan or a line of credit, by phasing the work over time or out of savings.
At Persson Construction, we are builders rather than lenders, so the borrowing itself is a conversation for your bank.
What we control is the number you end up financing, and that gets settled before construction starts.
Equity is the common route.
Tapping the equity in your current home tends to look better than moving when mortgage rates make buying somewhere else expensive, and it puts the money into a house you already want to be in.
That is often the real driver. People in Portsmouth and Rye are not trying to leave.
They like where they live, and they want the house to catch up to their life.
Talk to your lender before you talk to us about numbers, though.
Find out what you can actually borrow against, because that ceiling shapes the whole conversation, and it is not a question a builder should be answering for you.
What An Addition Actually Costs Here
Our additions have run from about $80,000 on the small end to $250,000, and the guide we hand clients puts the range at $150,000 to $500,000 and up.
Both numbers are real.
They describe different kinds of projects.
A garage addition runs $80,000 to $150,000.
A second-story addition runs $100,000 to $400,000, depending on how much structural work and system upgrading it takes.
A finished basement lands between $45,000 and $120,000.
Here is what we actually built. In 2024, we completed three additions, and they averaged $500,000 each.
That is the top of every published range, not the middle of it, and this year we are aiming for additions between $400,000 and $500,000.
So if you are budgeting from the low end of a range you found online, adjust.
Two things eat more of the budget than most people expect.
Labor takes close to half. Permits and inspections add both cost and calendar time on top of that.
Neither is negotiable, and neither shows up in the finished photos.
Getting To A Number You Can Take To A Lender
We start with a Comfort Zone Budget.
It is a 30,000-foot view of your project, a preliminary range built from similar projects we have finished, plotted on a gauge that runs from a budget version of your addition through the middle, where most projects land, up to the version with everything on it.
We show you photos of comparable projects next to it so the numbers attach to something real.
That is the figure to take to your lender first, because it is honest about being a range.
If it works, you sign a Project Development Agreement, and we build the real number.
That phase produces three conceptual plans for the key areas, a layout refined enough to price, a written scope, material allowances, and a working budget built from your actual selections rather than averages.
Then our subcontractors and vendors walk the site together on Trade Day and price off the real drawings.
What comes out of that is a construction agreement.
That is what you finance.
Why The Order Matters More Than The Rate
We have watched this go wrong the expensive way.
Homeowners hire a designer first, get plans they love, bring them over, and the price comes back at $700,000, against a budget that was never anywhere near that.
Now everything gets redesigned to come back down into range.
You pay for that redesign. You pay the designer again, and you wait.
Bringing us in early, alongside the architect or designer, is what keeps the drawings inside the budget while they are still being drawn, especially on an older home.
A better interest rate will never save you as much as not paying for the same set of plans twice.
Phasing An Addition Instead Of Borrowing It All At Once
Borrowing the whole amount up front is not the only option.
We run phased addition projects specifically so the scope, the schedule, and the budget can all be spread across more than one year.
It is a real answer for people who want the addition and do not want the debt all at once, and so is starting smaller.
It also is not free.
Every phase carries its own setup and mobilization costs, and it extends how long your daily life is disrupted, so you are trading financial breathing room for a longer construction period.
If you are choosing between phasing and borrowing more, that is the actual tradeoff to weigh.
One more thing worth knowing before you decide how much to borrow.
An addition does not return its full cost at resale, so if the plan depends on getting all of it back when you sell, the math will not work.
The reason to build is usually the problem you are solving, whether that is space, layout, or a neighborhood you are not willing to leave.
Where We Can Move The Number, And Where We Can’t
Once you have a number, there are levers, and we will tell you which ones we can pull.
Selections are the biggest ones. Are we using top-end windows on this project or middle-range ones? Same question on cabinets.
We present what we think fits the project, and when the budget will not carry it, we bring options and let you decide what gives you the best return.
Every allowance gets written down during planning, so choosing a finish later does not reopen the whole number.
We also work as your advocate with the trades, pushing subcontractors and vendors on pricing and on lead times, and on quality, when letting it slide would be easier for us.
Priorities are the other lever.
During planning, we run a Must, Should, Could, and Will Not Have exercise, and the Will Not Have column is the one that protects your budget.
Deciding what you are willing to give up early is how the budget stops being decided for you later.
There is one thing we would rather you not cut.
Build in a contingency of 10 to 20 percent, especially on an older house, because what is behind the walls is the part nobody can price in advance.
Finance the contingency along with the project. Borrowing it later, mid-construction, is the worst time to be asking.
From Range To Real Number With Persson Construction
The main thing to take away: get a number you can actually borrow against before you commit to drawings, because the sequence costs you more than the interest rate ever will.
Find out early whether your budget and your plans are in the same range, and phasing stays on the table if they are not.
