Buying and selling your home? There’s an app for that. Well not exactly, but there’s plenty of high-tech help available to guide you through the process.

The iZillow app gives you access to data on more than 80 million homes, including square footage and an estimate of fair market value. Take a drive around your possible new neighborhood and see home values pop up on your phone with real-time real estate info.

Get real-time mortgage rates from hundreds of lenders nationwide with the Mortgage Marvel app. Use it to compare rates and fees – prices reflect transaction-related pricing adjustments, such as loan amount, loan-to-value ratio and property type – and view disclosure information for all rates. When you’re ready, you can select a lender, fill out an application and be approved.

The RulerPhone app lets you use your iPhone as a tape measure to see if your couch will fit in your prospective new home. Place any credit-card-sized card next to an object, take a picture with the phone and align your image with the card placeholder displayed on-screen. A ruler will be displayed, allowing you to adjust the measurements with the drag of a finger.

The ExpertVideo: Home Repair app brings valuable home repair how-to videos to the palm of your hand. More than 20 videos are available, covering how to repair concrete steps, paint kitchen cabinets or patch a drywall hole. Still have questions after watching? A moderated discussion panel gives you answers.

Keep home improvements and routine maintenance tasks organized with the Homeowner Calendar app, featuring a calendar of monthly tasks, such as checking smoke alarms, cleaning air filters or cleaning your gutters. Alerts let you know when tasks are coming up, and the application allows for custom additions.
