As agents, staying in touch with your clients is critically important. We should add value to their lives on a regular basis, not just at the time of a transaction. This way our costs seem so much more palatable. Why not suggest doing a home energy assessment to your clients? Maybe gift this to them upon closing? I know few people who wouldn't like to save a buck.....and help this planet consume more efficiently.
A professional assessor can identify numerous areas of energy cost-savings within a home - you'd be amazed! - that can save lots. These assessments cost around $400. Most opportunities exist around heating and cooling and insulation. Did you know that many people have too large air-conditioners that fill up a room too quickly with cold air that adds to moisture and condensation: a smaller unit may use less energy and achieves the same cooling. This may be especially valuable to renters.... doing right by renters may lead them to be loyal buyers in the future? Leaking ducts and crawl spaces are other opportunity areas. A caulking gun can perform wonders!
Timed thermostat controls for heating and cooling can substantially reduce costs and usage too. More energy-efficient new appliances can make a big difference. Newer water heating systems can improve energy efficiency anywhere up to 300%! Switching from incandescent lighting to LED's can save up to 85% in energy usage.
You get the idea. Herein lies an opportunity to inform your clients and reminds them that you are a real estate advisor who cares about much more than just a commission check!
