NYC HOMEOWNER CALCULATOR
Stay—or make the move?
A low mortgage rate can make a home difficult to leave. New York transaction costs can make the decision harder still. Put both on the same page before you decide what the next home is worth to you.

For a homeowner with a mortgage in the threes, today’s market can create a peculiar kind of wealth: a loan that is cheap to keep and expensive to replace. The home may no longer fit. The equity may be substantial. Yet selling means giving up financing that cannot simply be carried to the next apartment.
That has frozen many move-up decisions into a false choice between a good mortgage and a better home. The more useful comparison is wider. What would you clear after selling? How much cash would the next purchase require? What portion of the higher payment comes from borrowing at a different rate—and what portion comes from simply buying more home?
SELLING IN NEW YORK
If the move starts with a sale, start with the home you already own.
A useful move-up plan begins with a realistic sale range, the costs attached to that sale and the amount of equity that can actually follow you to the next purchase. ELIKA can prepare a private pricing and sale strategy for your property.

Send ELIKA the basics. We can review the current home, likely sale proceeds and the next purchase without turning this into a public valuation request.
THE RATE IS AN ASSET. IT IS NOT THE HOME.
A cheap mortgage can distort the comparison.
Homeowners tend to remember the rate because it is unusually visible: a number printed on every statement and easy to compare with the rate on a new loan. But the rate is attached to a balance, not to the whole value of the home. A buyer moving from a smaller mortgage into a more expensive property is changing two things at once—the cost of money and the amount of money being borrowed.
That distinction matters. The calculator isolates the financing-rate premium by applying both rates to the same new loan. It then separately shows the larger household question: the difference in monthly carrying costs and transaction costs.
NEW YORK FRICTION
The round trip is expensive before the first mortgage payment.
In New York City, a move can involve brokerage, city and state transfer taxes, legal fees, building charges and preparation costs on the sale. The purchase may add mansion tax, title and recording costs, mortgage recording tax, lender charges and another round of legal and building fees.
Those costs do not mean a move is a mistake. They mean the holding period matters. A move made for more space, a different neighborhood, accessibility, schools, family or quality of life can be entirely rational even when the spreadsheet shows a higher five-year cost. The useful number is the price of that choice, not a verdict on whether to make it.
WHAT STAYING COSTS
Doing nothing is not financially neutral.
A homeowner who stays keeps the favorable loan and avoids another round of transaction costs. But staying can also mean carrying a home that no longer fits, delaying a purchase while prices change, or keeping equity concentrated in a property that no longer serves the household.
This calculator therefore treats the decision as a comparison rather than an instruction. It shows the cash and carrying-cost consequences of each path. It does not attempt to price the personal value of an extra bedroom, a shorter commute, a different building or five more years in a home you have outgrown.
HOW THE ESTIMATE WORKS
What is—and is not—in the model.
Mortgage principal and interest, entered taxes and monthly charges, estimated NYC/NYS transfer taxes, buyer mansion tax, selected buyer/seller closing costs, principal paydown and optional appreciation assumptions.
Income-tax consequences, capital-gains exclusions, tax deductions, opportunity cost of cash, renovation overruns, financing points, CEMA savings, sponsor concessions, tax abatements, assessments or property-specific legal adjustments.
Cash housing outlay over 60 months minus modeled principal reduction. Down payment is treated as equity rather than an expense; appreciation is shown separately in projected equity.
WHEN THE NEXT HOME IS REAL
Move from the scenario to the property.
Sell or Stay answers the household question. Once a particular apartment or townhouse is in view, model that home’s financing, taxes, common charges or maintenance and ownership horizon with True Carry Cost—or add it to My Home Search and keep the comparison beside your shortlist.

The automatic transfer-tax assumptions reflect published New York City and New York State residential transfer-tax rules; mortgage recording tax is an estimate and should be confirmed through ACRIS, your lender and attorney.
