Let's face it, people love to save money. Better yet, when they can save money by the help or suggestion of someone else, they benefit and the suggestor benefits. With the housing market taking a decline in many areas of the country, this is our chance as agents to help our clients save some money if they bought their home when the market was higher than it is now.
One of the things that many people tend to forget about until it's due is our property taxes. They become even more forgetable if they are paid through an impound account. So, get in contact with your past clients whose homes may have lost value and suggest that they contact the county assessors office and request that a new assessment is done. If the new assessed value comes in lower than the current value, they can have their property taxes adjusted, and save some money in the long run.
Run some comps for each client before contacting them. Make sure that you can justify a lower assessed value, and have the comps ready to turn over to the client to justify the lower value. Your clients will love you for this, and think about you everytime taxes are due, keeping you in the forefront of their thoughts...which is where you want to be.
