It's a well known fact that the #1 mistake that buyers could make when deciding to buy a home is miscalculating soft cost.
If you are searching in Cedar Park, North Austin and Round Rock areas to buy a home, be sure to calculate into your monthly budget the cost of toll roads. The 183A and 45 Toll Roads can be deceiving when you are driving on them. Many of my out-of-town visiting clients don't even realize they are on the Toll road and end up getting a bill in the mail.
Having a Texas Toll Tag does reduce the cost of the tolls (and the tag will work for you statewide), but I would suggest estimating $40-$85 into your monthly budget (double the amount for two cars) if you plan to use to toll roads daily. Both Toll roads to have roads available to avoid the toll, but you will be dealing with some traffic lights -- so plan some extra time in your daily commute.
Add the Toll Tag estimated costs to your other soft costs (which could include HOA fees, Utilities, Landscaping upkeep, pool costs, pest control, HVAC maintenance costs, etc.)
I hope this helps you make a smart and knowledgeable decision when you decide to buy a home. Thank you for reading!
