When you’re shopping for a home in Northwest Austin, the listing price is only one number in the equation — and it’s often not the one that catches buyers off guard. Property taxes and homeowners insurance both get rolled into your monthly payment through escrow, and both have climbed here over the past several years. If you don’t factor them in early, they can quietly push a home outside your real budget.
I’m Robbie English, Broker and REALTOR at Uncommon Realty, and walking clients through the full monthly number — not just the mortgage — is part of every home search I run.
TLDR: Estimating the True Monthly Cost of a Home
- Property taxes in the Austin area run close to 2% of assessed value in most jurisdictions.
- Homeowners insurance has risen significantly here in recent years — get a real quote before you’re under contract, not after.
- Taxes and insurance are collected through escrow, so they directly change your monthly payment, not just your annual costs.
- Two homes at the same price can have very different real monthly costs depending on age, roof, and location.
- Get quotes early enough to still walk away if the numbers don’t work.
The Number That Isn’t on the Listing
An online mortgage calculator will estimate your loan payment based on price, down payment, and rate — but it usually leaves out taxes and insurance, or uses a generic placeholder that doesn’t reflect your specific property. In the Austin area, the combined property tax rate typically runs close to 2% of assessed value, depending on which taxing entities apply to a given address. On top of that, insurance premiums here have risen substantially over the last several years, driven by hail risk, construction costs, and rebuilding expenses — the rate of increase has slowed recently, but premiums remain well above what they were a few years ago.
Why Buyers Get Caught Off Guard
Most buyers don’t get a real insurance quote until they’re already under contract, which means the number shows up right when they’re least able to walk away without losing momentum on the deal. By then, some buyers just accept whatever quote comes in to keep things moving rather than shopping around.
The fix is simple: get a homeowners insurance quote for a specific property early in your option period, not after you’re emotionally committed. It costs you nothing to ask, and it gives you real leverage to renegotiate or walk away if the number changes your budget significantly.
A Real Example
Say a home is listed at $600,000 with 20% down. Your mortgage payment covers principal and interest, but your lender will also collect roughly 1/12th of your annual property taxes and insurance premium every month and hold it in escrow. At a roughly 2% tax rate, that’s about $1,000 a month in taxes alone before insurance is even added. Insurance on a home that size in this area often runs in the $3,000-$4,000 per year range, adding another few hundred dollars a month. None of that shows up in a generic mortgage calculator — it only shows up once you’re looking at a specific property.
Planning Before You Fall in Love With a House
When I work with buyers, we look at what the full monthly payment will actually be before we tour, not after an offer is accepted. That means pulling a realistic tax estimate for the specific address and getting an actual insurance quote, not a rough guess, so the number you’re comparing against your budget is close to what you’ll actually pay.

Why Two Similar Homes Can Cost Very Different Amounts
Insurance costs vary a lot based on the age of the home, the roof material and age, proximity to flood-prone areas, and even the materials used in construction. Two homes listed at the same price can end up with monthly payments that differ by a couple hundred dollars once insurance is factored in. If you’re deciding between two similar-looking listings, that difference is worth knowing before you make an offer, not after.
Don’t Skip This Step
Taxes and insurance aren’t afterthoughts — they’re core parts of what a home actually costs you every month. Skipping this step is how buyers end up qualified for a loan on paper but stretched thin in reality once the full payment lands.
