Buying a home in Zilker / Barton Hills: what to know before you finance
In Zilker and Barton Hills, two things shape the loan before price does: whether the lot sits in the Barton Springs Zone, which limits impervious cover, and whether your loan amount is above the conforming limit. Check both by address, then decide between a conforming loan, a jumbo loan or a non-QM option.
Zilker and Barton Hills sit just south of Lady Bird Lake and west of South Lamar, around Zilker Park and Barton Springs. This page covers the housing you’ll see, what each type means for a loan, price context, taxes and the programs that fit. For citywide context, start on our Austin mortgage broker page.

Zilker and Barton Hills at a glance
- Where it is. Wikipedia describes Zilker as roughly bounded by Lady Bird Lake on the north, the Union Pacific line (Lamar Boulevard south of Oltorf) to the southeast, Barton Skyway to the south and Rabb Road and Azie Morton Road to the west. Barton Hills sits directly northwest and connects to Zilker Park by the Barton Creek Greenbelt.
- The park. In 1918 Andrew Jackson Zilker deeded 35 acres around Barton Springs to the City of Austin. Zilker Park now covers about 350 acres, and the Zilker Park Historic District was added to the National Register of Historic Places in 1997.
- The houses. The first homes in the Zilker area went up in the late 1920s, so the housing ranges from older cottages to recent rebuilds.
Homes in Zilker / Barton Hills: housing types and what each means for your loan
Older single-family homes. Many streets still have older, smaller houses on modest lots. Appraisers and inspectors look hard at foundations, drainage, roofs and any additions that may not have been permitted. None of that blocks a loan, but it can add conditions. If you plan to fix what the inspection finds, a rehab loan can fold the work into the financing.
Rebuilds and new modern homes. Some buyers purchase an older house for the lot. If you’ll live in it first, a standard purchase loan works. If you’ll tear it down soon after closing, the value is mostly land, and a construction loan or bridge loan may fit better than a purchase loan.
Two or three units on one lot. Austin’s HOME amendments, adopted in December 2023 and in effect since February 5, 2024, allow up to three housing units on lots zoned SF-1, SF-2 or SF-3, subject to City site standards. How those units are owned, as one property or split into a condo regime, decides which loan fits. One owner with two or three units is financed as a 2–4 unit property. Units split into a condo regime are reviewed as condos, and a small regime that doesn’t meet agency rules may need a non-warrantable condo loan.
Condos and townhomes. Condo buildings get a project review: owner-occupancy, reserves, insurance and any litigation. We request the HOA questionnaire early so problems surface during your option period.
The Barton Springs Zone. Austin’s Save Our Springs (SOS) ordinance, approved by voters on August 8, 1992 and codified by Ordinance No. 920903-D, limits impervious cover for new development in the Barton Springs Zone: 15% in the recharge zone, 20% in the contributing zone within the Barton Creek watershed and 25% in the rest of the contributing zone, on a net site area basis. A 2023 City Environmental Officer memo shows how a single South Austin site can straddle the Barton Springs Zone and another watershed with different rules. If you plan to add on or rebuild, confirm with the City which rules apply to the lot before you count on a bigger house in your numbers.
Flood risk. Parts of the area sit near Barton Creek and other drainage. Check the address on the FEMA Flood Map Service Center before you write an offer. If the home is in a special flood hazard area, the lender will require flood insurance, and that premium goes into your payment.

The 2026 conforming limit and when you need a jumbo loan
FHFA set the 2026 baseline conforming loan limit for a one-unit home at $832,750. Travis County uses the baseline limits: $832,750 for one unit, $1,066,250 for two, $1,288,800 for three and $1,601,750 for four. A loan amount above the county limit is a jumbo loan, with its own down payment, reserve and documentation rules; see our jumbo loan page.
Property taxes and HOA dues in Zilker / Barton Hills
Homes in Zilker and Barton Hills inside the City of Austin are typically taxed by the City, Travis County, Austin ISD, Austin Community College and Central Health. Confirm the exact taxing units and appraised value on the Travis Central Appraisal District record for the address. For homes inside the City of Austin, the City’s adopted rate for fiscal 2026–27 is $0.579948 per $100 of taxable value. That’s one line of the bill; add the other entities from the TCAD record before you estimate a payment.
- Homestead exemption. If you live in the home, file your homestead exemption with the appraisal district after you close. Texas law exempts $140,000 of a homestead’s value from school district taxes, plus another $60,000 if you’re 65 or older or disabled (Tax Code §11.13). See the Texas Comptroller’s exemptions page.
- Homestead cap. Once your homestead exemption is in place, the taxable value of the home can’t rise more than 10% a year, plus the value of new improvements (Tax Code §23.23).
- Protest deadline. If you disagree with the appraisal, the protest deadline is generally May 15 or 30 days after the appraisal district mails your notice, whichever is later (Tax Code §41.44).
- After a rebuild, the new home is reappraised on its improvements, so the old house’s tax bill can understate what you’ll pay.
- Condo dues. Monthly HOA dues and any special assessments count in your debt-to-income ratio or DSCR. Get them in writing.
Loan options that fit Zilker / Barton Hills
Agency loans for owner-occupants
For buyers who’ll live in the home, conventional, FHA and VA loans are usually the starting point.
- Conventional loans for single-family homes, many condos and 2–4 unit properties.

Non-QM and DSCR loans for Zilker / Barton Hills
Many Zilker and Barton Hills buyers are business owners, investors or people with strong assets and uneven income. Non-QM loans qualify you on something other than tax-return income. CapFi works with lenders across the non-QM range, and terms vary by lender.
- Bank statement loans qualify self-employed buyers on business or personal bank deposits instead of tax returns. They are non-QM loans and come in a range of loan sizes.
- P&L loans qualify on a profit-and-loss statement for business owners.
- Asset depletion turns savings and investments into qualifying income for buyers with assets but uneven pay.
- Interest-only loans lower the early payment for buyers whose income comes in larger, less regular amounts.
- DSCR loans qualify a rental on the property’s rent rather than your income. Austin short-term rentals need a City license; see the STR section on that page.
- Non-warrantable condo loans for buildings and small condo regimes that don’t meet agency project rules.
- Foreign national loans for buyers who live outside the U.S.
How CapFi shops more than 50 wholesale lenders for Zilker / Barton Hills buyers
A bank gives you its own rules. A broker can match the property and your income to a lender whose rules fit them. In Zilker and Barton Hills that matters, because loan size, a rebuild plan or a small condo regime can each narrow the list of lenders that will say yes.
Here’s how we work a file:
- Property first. We look at how the home is owned (fee simple, condo regime, 2–4 unit), the flood map, any rebuild plan and whether the loan amount is above the conforming limit.
- Income second. W-2, self-employed, rental income or assets: we pick the documentation path that shows your income most completely.
- Shop. We compare programs across more than 50 wholesale lenders and show you the options side by side. Any rate we quote comes with its APR.
- Manage to close. We order HOA or condo documents early, keep your agent updated and work the appraisal and underwriting conditions.
Zilker / Barton Hills home loan FAQs
Does the SOS ordinance affect buying a home in Zilker or Barton Hills?
It can if you plan to build or add on. The SOS ordinance limits impervious cover for new development in the Barton Springs Zone, from 15% to 25% depending on the zone. It doesn’t stop a purchase loan, but confirm the lot’s rules with the City before you plan a bigger house.
Do I need a jumbo loan to buy in Zilker?
Only if your loan amount is above the conforming limit. In 2026 the Travis County limit for a one-unit home is $832,750. A loan above it is a jumbo loan, with stricter down payment and reserve rules. A larger down payment can keep some purchases conforming.
Can I finance a teardown or rebuild in Zilker or Barton Hills?
Yes, but not always with a standard purchase loan. If you’ll live in the existing house first, a regular mortgage works. If you’ll demolish soon after closing, most of the value is land, so a construction or bridge loan may fit better. Check the lot’s impervious cover rules first.
Do I need flood insurance in Zilker or Barton Hills?
Only if the home is in a FEMA special flood hazard area; then the lender requires it. Homes near Barton Creek and other drainage are the ones to check first. Look up the address on the FEMA Flood Map Service Center before you write an offer, and price a policy either way.
Can I buy a Zilker duplex and live in one side?
Yes. Living in one unit of a two- to four-unit property lets you use conventional, FHA or VA financing, and many lenders count part of the other unit’s rent toward your income. The appraiser’s rent estimate or existing leases usually support that figure. Requirements vary by lender.
Can self-employed buyers get a mortgage in Zilker or Barton Hills?
Yes. If your tax returns show enough income, a conventional loan may work. If write-offs lower your taxable income, a bank statement or P&L loan qualifies you on deposits or business statements instead. CapFi compares those non-QM options across more than 50 wholesale lenders.
Can I qualify using savings instead of income?
Often, yes. An asset depletion loan turns eligible savings and investment balances into monthly qualifying income, which helps retirees and buyers with large assets but uneven pay. It is a non-QM program, so terms, rates and the assets that count vary by lender.
How do I lower property taxes on a Zilker home I live in?
File a homestead exemption with the Travis Central Appraisal District after you close. It removes $140,000 of value from school taxes and caps the yearly increase in taxable value at 10%, plus new improvements. You can also protest the appraisal by May 15 or 30 days after your notice.
