Thanks to ultra-low mortgage rates, it's an excellent time to buy or sell a home across the U.S. But housing prices are rising — up an average 5.9% over the last year for an existing single-family home, the National Association of Realtors reported Tuesday.

What about in Texas? Is the state's housing market too pricey for buyers? Not-so-great if you've got a home you want to sell? Or just right — for everybody?

Home values provide some answers. They indicate that the market in Texas is heating up, according to Zillow, though you might find vast differences from one city or one corner of the state to the next.

Current home values in Texas

Home values have been rising throughout Texas and are up 5.32% from a year ago.

Statewide, the median value for a single-family home — meaning half are worth more, half are worth less — is currently $198,100 , Zillow says.

Could you afford that? Let's say you want to buy that mid-priced home using a 30-year fixed-rate mortgage at this week's average interest rate, which is a low 3.69%, says mortgage company Freddie Mac.

With the 30-year mortgage rate at 3.69% and the median home price for Texas at $198,100 , a representative monthly mortgage payment would be $910.70.

How the Texas housing market stacks up

Property values in Texas are high by historical standards and are lower than what the typical house is worth nationwide.

The median home value throughout the U.S. is $229,600, which is up 4.88% from a year ago.

Zillow predicts U.S. home values will rise 2.2% over the next year, while in Texas, they're expected to rise 3.38%.

Homes are going on the market in Texas at a median price of $110 per square foot, versus $155 per square foot nationwide.
