Most affordability advice stops at the sale price. In this part of New York, the sale price is maybe two thirds of the story. The tax line and the insurance line ride in the same monthly payment, and in some south Monroe County towns the tax escrow is a serious number.

This post walks through all four parts of a monthly payment, shows the principal and interest math at the current rate, explains why I will not quote you a tax rate I pulled off a national website, and gives you a way to work backward from a payment you can live with to a price you should be shopping.

The four parts of the payment

When a lender says your payment is $2,300, that number usually contains:

• Principal and interest. The loan itself. Fixed for the life of a fixed rate mortgage.
• Property taxes. In Monroe County that means a county and town bill plus a school bill. Most buyers escrow both, so the annual total gets divided by twelve and added to the payment.
• Homeowners insurance. Also usually escrowed.
• Mortgage insurance. Applies on most conventional loans with less than 20 percent down, and on FHA loans regardless of down payment.

Add a homeowners association fee if the property has one. Townhouse and condo communities around Henrietta, Brighton and Pittsford often do.

What principal and interest costs right now

Freddie Mac's Primary Mortgage Market Survey put the 30 year fixed rate at 6.65 percent for the week of August 20, 2026, against 6.58 percent a year earlier. The 15 year fixed was 5.95 percent. Rates have been close to flat year over year.

One caveat worth knowing: that survey reflects conventional, conforming, fully amortizing purchase loans with 20 percent down and excellent credit. Your quote may differ. Freddie Mac's own chief economist made the point on that release that borrowers should shop more than one lender.

Here is the principal and interest math at 6.65 percent over 30 years. The first two price points are reported medians. The third is an illustration, because a lot of what sells in the southeast towns prices above the metro median.

Those are the smallest numbers on your statement. Everything below adds to them.

The property tax line, and why I will not guess it

I do not have a verified current tax rate table in front of me for Henrietta, West Henrietta, Pittsford, Brighton, Mendon, Rush or Honeoye Falls, so I am not going to print one. Rates differ by town, by school district and by parcel, and a stale rate copied from an aggregator is worse than no rate at all.

What I do instead, for every property a client is serious about:

• Pull the actual current tax bills for that parcel from the Monroe County property records, town and county plus school, not an estimate.
• Check the assessed value against the price you are offering. If the assessment is well below your offer, understand how that town handles reassessment before you assume the current bill is your forever bill.
• Check whether the seller's bill reflects a STAR exemption or any other exemption that may not carry over to you.
• Ask the lender to escrow off the real figure, not a rule of thumb, so your payment does not jump at the first escrow analysis.

Two homes at the same price in two different towns can carry meaningfully different monthly payments. That is the single most common surprise for buyers relocating into this market.

Insurance, and getting the quote early

Get a homeowners quote while you are still in your inspection window, not the week before closing. What tends to move the premium on the housing stock here: roof age, the age and type of electrical service, the heating system, whether there is a wood burning appliance, and whether the basement needs a water backup endorsement. Older homes with original systems can quote higher than a buyer expects. If a carrier balks at a roof or a panel, that is information about the house, and it is better to have it before your contingencies expire.

Mortgage insurance and the down payment question

The gap between 5 percent down and 20 percent down is not only mortgage insurance. Look at the table again. On a $252,800 purchase, 20 percent down cuts principal and interest by roughly $244 a month, before you count the mortgage insurance you also avoid. It also costs you about $37,900 more in cash at the table.

Most first time buyers I work with in this market are not putting 20 percent down, and that is fine. Just plan the Rochester NY down payment decision on both sides: cash out of pocket now, versus payment for as long as you hold the loan. And keep reserves. Closing costs, the first tax escrow deposit and moving expenses all land in the same month.

What salary do you actually need

Lenders qualify you on debt to income, not on price. A conservative way to work backward: take the full payment, including taxes, insurance and mortgage insurance, add your car payments, student loans, minimum credit card payments and any child support obligations, then divide by 0.36. That gives a monthly gross income figure. Multiply by twelve.

Worked example. Say your lender quotes a full payment of $2,400 on a house you like, and you have $400 a month in other debt. That is $2,800 in total obligations. Divided by 0.36, you need about $7,780 a month gross, roughly $93,000 a year. With no other debt, the same payment pencils at about $80,000. Some loan programs stretch past a 36 percent ratio with strong credit and reserves, so treat this as a floor for comfort rather than a hard cutoff. The pre-approval is the real answer.

Worth keeping in view: Census data cited by the Rochester Beacon in July 2026 showed 24.7 percent of homeowners in the city of Rochester were cost burdened in 2024, meaning housing ate more than 30 percent of income, alongside 50.9 percent of renters. Both figures were down from 2015. Qualifying for a payment and living well with it are two different tests.

Budget for a competitive offer, not just a list price

Supply here has been tight. A regional figure cited from RPR put December 2025 at 0.52 months of inventory. Houzeo reported 0.33 months for the city of Rochester in July 2026, down from 0.79 a year earlier. A balanced market is generally described as five to six months. Metro prices rose 7.2 percent year over year in the first quarter of 2026 according to NAR data reported by the Rochester Business Journal, the tenth largest first quarter increase among the nation's 235 largest markets.

What that means for your budget: if you go above list, the difference between contract price and appraised value comes out of your cash, not your loan. Decide before you write an offer how much appraisal gap money you have, and treat it as separate from your down payment.

Be careful with town level numbers online

One example. Redfin's December 2025 median sale price for Pittsford showed a 38.6 percent year over year drop, built on three sales. Three. That is noise, not a trend. On the other side, a single Houzeo page for the city of Rochester in July 2026 reported 51 median days on market next to a claim that 88.83 percent of homes sold above asking, two readings that cannot comfortably describe the same market. Also check the state on any page you land on: searches for "Rochester housing market" regularly surface Rochester, Minnesota.

For an actual price picture in a specific town, ask a licensed agent to pull recent closed comps in that school district and that price band. That is a five minute job with MLS access.

The order I would do this in

1. Decide the monthly payment you want to live with, all in.
2. Get pre-approved so you know the rate, program and mortgage insurance cost you personally qualify for.
3. Pick two or three towns and pull real tax bills on comparable homes to see how much of your payment the tax line consumes in each.
4. Subtract taxes, insurance and mortgage insurance from your target payment. What is left is your principal and interest budget.
5. Convert that back to a loan amount, add your down payment, and shop that price.
6. Hold cash aside for closing costs, escrow setup and a possible appraisal gap.

If you want help running these numbers on a specific street or a specific house, send me the address. I will pull the tax bills, the closed comps and an honest read on what the payment looks like. Schedule a time with Khem Kadariya and bring your questions.

About this data

The figures in this post were compiled from publicly available sources including Houzeo, Zillow, FRED (Federal Reserve Bank of St. Louis), Redfin and the Rochester Business Journal, along with other public market data. Real estate numbers change quickly, and these were accurate as of August 2026. For current figures on a specific home, street, or town, ask me directly rather than relying on a published average.
