You can work with whomever you want.
Building trust is an important part of the home buying process.
You might want to read the Realtors Code of Ethics. If you deal with a Realtor, it is more than just a licensed person.
Good luck. If you would like a referral to a great REaltor in your area, let me know.
If you are that unhappy, you should seek advice elsewhere, but you cannot sign another contract unless/until you have severed ties with the first agent.
Please let me know if you wish to have further communication about representation. Good luck!
Sorry to hear about you bad experience it is very unfortunate, not all realtors and loan officers are like this and I would recommend that you talk to your friends, relatives, or co workers and see if they have anyone they would refer, or check to see if there are any complaints on file at the MN Commissioner of Commerce Office for the next agent you hire. You certainly have the right to fire your agent, you should re-read the contract between you and your agent to see what the cancelation language say's.
Regret to hear of your challenges and issues with your Realtor. Clearly, there is lack of trust, doubts about capabilities. Clearly there is a lot going on for your Realtor in managing the detailed loan paper work now required as well as managing the real estate buying transaction.
If your transaction is still in process you need to continue with your Realtor, if your buy offer did not pan out
Then it maybe prudent to move on.
Trust you have not signed any agreement with her.
Best of Luck
Most MN contracts for representation contain a cancellation clause - you will need to review your documents and find out what is required to cancel your contract. In most situation (on MAR Approved Forms) contracts can be cancelled by mutual written consent. If your agent won't let you out of the contract you can certainly ask the broker to be reassigned to another agent.
As far as switching loan officers. As long as you haven't signed a contract to have her represent you on the loan (very rare but possible) you should be able to switch loan officers at will.
Good luck with your purchase.
