Real estate investor of 23 years here. Just like the total cost of attendance at university is not the same as tuition (fees, travel, books, room, board), total cost of ownership is key.
We're still at a great point in time for interest rates, and frankly I think that's driving ... not an irrational exuberance in real estate, but simple inflation across the board.
check taxes, check utilities, check maintenance, check HOA fees (all these are potentially big in Texas). (Price) Mortgage or cash financing is the easily definable piece of the equation.

PS and since this will be your primary residence, finances aren't the most important thing. If you are happy there, then go for it.
