This post does one thing: it runs the arithmetic on a specific move. You sell a home worth about $285,000 somewhere in the county's mid price band, Henrietta or Rush or West Henrietta, and you buy in Brighton at $424,150. By the end you will know the monthly principal and interest at today's rate, how much cash the transaction eats, which lines I refuse to estimate for you, and how to swap in your own numbers in about ten minutes.

I am going to be plain about the limits of the data too. Some of what gets published about this market does not hold up. I will tell you which parts I trust.

Where the two headline numbers come from

The $285,000 side is Zillow's average home value for Monroe County: $285,439, up 4.1 percent year over year, updated 4/30/2026. That is a modeled valuation of all homes, not a median of sold homes, and it is several months old. Use it as a rough anchor for a mid band house, not as your listing price.

The $424,150 is Brighton's median sale price for the second quarter of 2026, from a local brokerage quarterly recap. Here is the full picture from that recap:

Two caveats I will not bury. That is a brokerage recap, not an MLS verified release, and it covers April through June. There is no published Brighton median for July or August 2026 as I write this. Also worth knowing: a quarterly median in a town Brighton's size moves on which houses happened to close, not just on what houses are worth. A quarter heavy on smaller postwar capes drags the median down without anyone's home losing value.

For context, the Monroe County median listing price was $319,900 in May 2026 per Realtor.com data on FRED. That is asking, not sold, and it covers the whole county. Brighton sits well above it.

The rate: 6.65 percent, and why it is not the story

Freddie Mac's weekly survey put the 30 year fixed at 6.65 percent for the week ending August 20, 2026. That followed 6.67 percent on August 13 and 6.69 percent on August 6. The same week a year earlier: 6.58 percent. The 15 year fixed averaged 5.96 percent on August 13, against 5.71 percent a year prior.

Seven basis points of movement over a year is noise. A 6.65 percent mortgage rate is not a reason to move and not a reason to wait. If you are a move up buyer in Monroe County, the decision hinges on your cash position and your monthly tolerance, not on rate timing.

The cash side: what the sale actually leaves you

Every number in this ledger is an assumption you should replace with your own. Commissions are negotiable and vary by agreement. I am showing the shape of the transaction.

Your loan in this scenario is $339,320. Notice what happened: a home you owned with $135,000 of equity turned into a home you own with $84,830 of equity. That gap is the transaction. It is the single most underestimated part of the cost of trading up in Rochester NY, and no monthly payment calculator shows it to you.

The monthly payment at 6.65 percent

Principal and interest only, 30 year fixed, 6.65 percent:

The rule to carry in your head: at 6.65 percent, every $10,000 you borrow costs about $64 a month. Bidding $15,000 over asking is roughly $96 a month for thirty years. That is how I want you thinking during a negotiation.

If you took the same $339,320 on a 15 year fixed at 5.96 percent, principal and interest runs about $2,856. Higher monthly, far less interest, much less flexibility.

The lines I will not make up

A Brighton NY monthly payment is not just principal and interest, and this is where most online estimates quietly fail you.

• Property taxes. I do not have a verified Brighton tax rate to quote you, so I am not going to invent one. What I can tell you is the arithmetic: every $1,000 of annual property tax adds about $83 to your monthly escrow. The combined county, town and school levy on a home in this price range is a substantial line. Before we write an offer I pull the actual tax bill for that address, not an estimate.
• Homeowner's insurance. Quote it on the specific house. Roof age, service panel and heating system all move the number.
• Mortgage insurance. If you put 10 percent down instead of 20, that $2,451 payment gains a monthly PMI line on top. Get the figure from your lender in writing before you commit to the lower down payment.

So the honest framing of this move: about $2,178 in principal and interest, plus a Brighton tax and insurance escrow you and I will look up together, minus whatever your current payment is. If your current principal and interest is $1,100, the payment side of the move is roughly $1,078 more per month before escrow changes, and the escrow change on a $424,150 house will not be small.

What Brighton's Q2 numbers do and do not tell you

A median down 8.2 percent year over year is worth knowing, and it is worth not overreading. It means there was room to negotiate in the spring. It does not mean sellers in Brighton are anxious. Zillow had Monroe County homes going pending in around 8 days as of 4/30/2026, which is stale but not a picture of a slow market.

One practical warning. If you search Brighton home prices online, you will get numbers from New Brighton and West Brighton on Staten Island and Brighton Beach in Brooklyn, running from roughly $545,000 to $772,000 in mid 2026. I have also seen a major listing aggregator file Downtown Rochester, Corn Hill and the South Wedge as Brighton neighborhoods, and one of them attached a Missouri school district to a Rochester page. Do not calibrate your offer off any of that.

Sell first or buy first

With $115,050 of your buying power locked inside your current house, sequence matters more than usual.

• Selling first gives you clean, non contingent offer terms and a known proceeds figure. It also means arranging somewhere to live if the closings do not line up.
• Buying first with a sale contingency is doable, but in a market moving at this speed the contingency costs you leverage on price.
• Bridge financing exists. It is expensive and it needs a lender conversation before you fall for a house, not after.

Run your own version

• Get a realistic sale number for your current home from recent closed comparables on your street, not from an automated valuation.
• Call your servicer for an exact payoff figure, not your remaining balance from the app.
• Subtract your selling costs. Ask for them itemized in writing.
• Take the remainder, split it between down payment and closing costs, and multiply the loan amount by 0.0064 for a quick monthly principal and interest at 6.65 percent.
• Add the actual annual tax bill divided by 12, plus insurance.
• Compare that total to what you pay now. Then decide.

If you want me to run those numbers on your specific house and on a specific Brighton listing, including the real tax bill rather than a guess, book a time with me. I will show you the whole ledger, including the parts that argue against moving. Schedule a meeting with Khem Kadariya.
