Should you keep renting in New Haven or put down roots and buy? It is a big decision, and it can feel unclear when you add up mortgage payments, taxes, and repairs on one side and rising rent and flexibility on the other. You deserve a simple, transparent way to compare both paths. In this guide, you will see a clear 5-year model you can run with your own numbers, plus an example that shows how small shifts in rates, appreciation, or rent growth can flip the result. Let’s dive in.
How to compare rent vs buy in New Haven
A good model looks at your total cash out over time, not just the monthly payment. It also credits you for equity you build and the net proceeds you could receive if you sell.
What costs go into owning
Your 5-year ownership model should include:
- Mortgage principal and interest on a 30-year fixed loan
- Private mortgage insurance if you put less than 20 percent down
- Property taxes based on New Haven’s local tax structure
- Homeowners insurance, and flood insurance if required
- HOA dues if you are buying a condo
- Routine maintenance and potential larger repairs
- Closing costs you pay at purchase and selling costs when you move
- Opportunity cost of your down payment if it could be invested instead
To check current rate trends, use the national weekly average from the Freddie Mac Primary Mortgage Market Survey. For a sense of historical price movement, review the FHFA House Price Index for New Haven County.
For property taxes, confirm how New Haven’s assessor calculates bills and the current mill rate at the City of New Haven Assessor. As you estimate insurance, remember that coastal or low-lying areas may need flood coverage. Check your flood zone on the FEMA Flood Map Service Center.
What costs go into renting
A fair rent model includes:
- Starting monthly rent for a comparable unit
- Annual rent growth
- Renter’s insurance (often required by landlords)
- Security deposit and moving costs
- Investment returns if you choose to invest the savings from not buying (for example, your down payment fund)
If you want a benchmark on typical rent data collection, the American Community Survey provides a neutral view of local housing costs. See the U.S. Census Bureau’s ACS program for background.
A 5-year baseline example
Below is a simple, illustrative scenario that follows the framework above. It is not a quote and not tied to any single New Haven listing. Your numbers will differ by neighborhood, property type, and timing. Use it to see how the math flows, then plug in your data.
Inputs we model
- Purchase price: $350,000
- Down payment: 10 percent ($35,000)
- Loan: $315,000 at 6.25 percent, 30-year fixed
- PMI: 0.5 percent of the loan per year (until loan-to-value reaches 80 percent)
- Property tax: 1.8 percent of home value per year ($6,300)
- Homeowners insurance: $1,200 per year
- HOA: $0 (single-family example)
- Maintenance: 1 percent of price per year ($3,500)
- Closing costs at purchase: 3 percent ($10,500)
- Selling costs: 6 percent of sale price
- Home appreciation: 3 percent per year
- If renting instead: $1,800 per month starting rent, growing 3 percent per year
- Opportunity cost: down payment invested at 5 percent per year
- Holding period: 5 years
What the math shows in 5 years
Here is a high-level view of cumulative cash flows and proceeds with the inputs above:
- Monthly principal and interest is about $1,937. Over 5 years, that is roughly $116,200 in payments.
- Add recurring owner costs: property tax (about $31,500), insurance ($6,000), maintenance ($17,500), and PMI (about $7,600 over 5 years). Include purchase closing costs of $10,500.
- Total owner outflow before selling is approximately $189,300.
- After 5 years at 3 percent annual appreciation, estimated sale price is about $405,700. After 6 percent selling costs and the remaining loan payoff, estimated net sale proceeds are about $87,300.
- Owner net cost over 5 years is total outflows minus net proceeds, which is roughly $102,000. If you include the opportunity cost of your $35,000 down payment not being invested at 5 percent, add about $9,700. Estimated owner net cost including opportunity cost is about $111,700.
Renting with the example inputs:
- 5-year rent outflow with 3 percent annual increases is about $114,700.
- If you invest the $35,000 down payment instead, the investment grows by about $9,700 at 5 percent per year over 5 years.
- Net renting cost equals rent outflow minus the investment growth, or about $105,000.
Result in this example: renting comes out about $6,700 cheaper over 5 years. Small changes in appreciation or interest rates can swing that result. The next section shows how.
What could move the result
- Appreciation: If annual appreciation is modestly higher than 3 percent, your net proceeds rise at sale. An increase of roughly a third of a point per year can be enough to close a small gap like the one above.
- Mortgage rate: A 1 percentage point change in rate can add or subtract roughly $200 per month on a $315,000 loan, which is about $12,000 over 5 years.
- Rent growth: Faster rent growth increases the cost of renting. Slower growth reduces it.
- Down payment: A larger down payment can eliminate PMI and reduce monthly costs. It also increases your opportunity cost if those funds could have been invested.
Sensitivity snapshot
The examples below use the same inputs as the baseline and change one setting at a time. These are rounded, illustrative estimates to show direction and magnitude.
| Scenario |
Estimated 5-year advantage |
| Baseline (6.25 percent rate, 3 percent appreciation, 3 percent rent growth) |
Renting by about $6,700 |
| Rate down 1 percent (to 5.25 percent) |
Renting by about $0 to $2,000 |
| Rate up 1 percent (to 7.25 percent) |
Renting by about $18,000 |
| Appreciation 0 percent |
Renting by about $58,000 |
| Appreciation 5 percent |
Owning by about $30,000+ |
| Rent growth 1 percent |
Renting by about $12,000 |
| Rent growth 5 percent |
Near break-even to owning slight edge |
| Down payment 20 percent (no PMI) |
Moves baseline closer to break-even |
What this means for you: if you expect to stay longer, believe appreciation will track above inflation, or can lower your rate and PMI, buying can become cheaper within a 5-year window. If you value flexibility, expect flat prices, or prefer to invest your cash, renting may win in the near term.
What to plug in for New Haven today
Use local, public sources to keep your inputs current:
Tip: Pull a few recent condo listings if you are comparing a condo to a single-family home. HOA dues can be several hundred dollars per month and can change your result.
Local factors to weigh in New Haven
- Neighborhood mix: Downtown and university-adjacent areas often have more condos and smaller units. Suburban-style areas have more single-family homes. Prices, HOA dues, and maintenance expectations differ by property type.
- Flood exposure: Portions of New Haven near Long Island Sound, like East Shore and Long Wharf, may have higher flood risk. A flood policy changes the insurance line in your model.
- Holding period: If you think you will move in under 5 years, transaction costs carry more weight. If you plan to stay longer, equity building and price appreciation matter more.
- Taxes and deductions: Mortgage interest is front-loaded in the early years of a 30-year loan. Actual tax savings vary with your income and whether you itemize. Consider speaking with a tax professional if you want a personalized view.

- Compare and test
- Total owner outflows minus net sale proceeds equals owner net cost.
- Compare to renter net cost.
- Run sensitivity tests for rates (+ or − 1 percent), appreciation (−2, 0, +3, +5 percent), rent growth (1, 3, 5 percent), down payment (3, 10, 20 percent), and holding period (3, 5, 7, 10 years).
- Interpret results
- If ownership is close to break-even in 5 years, small improvements like a slightly lower rate, a modestly higher appreciation assumption, or lower HOA/insurance can tip it.
- If renting is much cheaper at 5 years, consider extending your horizon in the model to 7 or 10 years or saving for a larger down payment to remove PMI.
