Herein, is it bad to switch Realtors?
Communication is key. Going behind the agent's back and using another Realtor to purchase a home is simply rude – especially if that buyer's agent has put considerable time into finding you a home. Instead, make sure you are open, honest and upfront with the agent about your decision to cut ties.
Additionally, how do you tell a realtor you're going with another agent? During your scheduled call, tell your real estate agent you've chosen to work with someone else and thank them for their time. They may ask if you've signed an exclusivity agreement with someone else. You don't need to disclose any other information if you don't want to.
Consequently, can you work for 2 real estate companies?
Yes, you need to obtain written consent from both brokerages. Even if the regulatory board in your state allow you to work with two firms, it doesn't necessarily mean your brokers would agree with the arrangement.
Can you change realtors after making an offer?
If you sign a contract with a Realtor, you can be bound by it for the length of time in the contract. If the realtor is willing to sign a release then you are free to 'change your mind,' but only with a signed release.
