Advantages of Building Over Buying Used Home

Less Competition

Buying a house comes with serious competition especially during spring and early summer. The National Association of Realtors (NAR) reports that the average time a house stays on the market is 30 days.

Building a house saves you from all the rat race involved in buying a home. You do not have to bother about things such as:

  • Market price
  • House showing
  • Fear of losing the home to another family

With homes flying off the market, you may end up losing your desired potential home to the competition.


You can never get it all right when you buy a home. Building your own house give you the liberty to customize its details to your lifestyle and taste.

You get to decide on the color of the paint, flooring, window/door size, layout, cabinets, and even doorknobs. Buying a used house leaves you with limited options unless you are willing to spend heavily on remodeling.

Less Maintenance Cost

Building a house eliminates the need to worry about maintenance expenses.

For the first few years, you’re less likely to deal with serious repair issues like:

  • Leaky roof
  • Failing HVAC systems
  • Faulty wiring
  • Septic tank repairs

Most importantly, several San Antonio homebuilders offer limited home warranties in case of damage.
