The real estate industry is very sensitive to economic changes like interest rates and the cost of materials in building houses. Interest rates in particular can easily swing the number of sales that are completed during any quarter of the year. Rising interest rates will slow down the sales and falling rates will aid the sales of real estate. This is an important fact in the real estate business as this can absolutely cause rapid changes in income from the sales that can be made.
With this in mind, the time to buy an agency that comes up for sale may be when the real estate business is in the doldrums. A hot real estate market will make an existing firm worth more, as their income will be higher during this period of time. Of course if you follow this course of action, you will have to wait out the slow down in the markets. Another factor in the purchase or start-up a real estate company is the state licensing requirements.
