Twenty years ago, a gallon of gas was about a dollar, and it took 5.5 years to save for a down payment on a home. Since the good ol’ days of ’98, home values have skyrocketed — nearly twice as much as incomes — and the average time to save for a down payment has gone up to seven years.

But don’t fret too much. Some Texas cities come in below the U.S. average, and that includes Dallas, which clocks in at 6.8 years.

To reach this conclusion, Zillow compared the change in median home values from 1998 to 2018 to the change in median income over the same 20-year period. The real estate site assumed that a person earning the local median income was saving 10 percent each month.

Houston buyers are treated with the least amount of time needed to save for a 20 percent down payment in the state: 6.2 years.

If you’re extremely eager to buy a house in the shortest amount of time possible, Houston might be the place to do it.

Houston and Dallas residents have it easier than Austinites when it comes to buying a home.

Those in San Antonio wanting to achieve their dream of being a homeowner have it a bit better, as they will need to save for 6.3 years.

Although Texans, especially millennials, are going to have to be patient with the saving process, things look much better in the Lone Star State than in California. In San Jose, it takes two decades (21.8 years) to save for a down payment. San Francisco and Los Angeles are barely better at about 18 years each.
