Main point: don’t trust the local government to do the right thing automatically. They are often backed up and have wrong information about your home. If you are already paying higher taxes for an approved expansion or remodel, make sure they have the right information on hand. By making one phone call I was able to increase my home’s value by ~$160,000.
Every so often I invite a realtor who has sold a home nearby to come over and give an assessment of my home. The realtor has perfect information about my neighborhood at the time because he sees all the offers. He knows the demographics of the buyers, how many people are interested versus the same time last year, and all sorts of other insights.
If you want to know the pulse of the market or get advice on what you could do differently to your home to increase its value for free, I recommend you do the same. Realtors are always happy to stop by to share their opinion and hopefully one day win your business. Even if they don’t win your business, at least they will be familiar with your house to pitch to their clients if you ever decide to sell.
