The people who can make of break your deal. Clearly identify who is helping you get:
1) Real information in real time...not automated valuations of properties. If an entity is not licensed in the state they are providing information about, take their advice like a grain of salt.
2) People who comment on places and neighborhoods but live in a different part of town or country. These people can be toxic to your decision making process. Do not allow others perceptions of people and places if they do not intimately know the area, community or otherwise. Stay local...with advice.
3) Are they qualified to help you? Carefully engage with people who are seasoned professionals. Have your personal checklist of what you want in a real estate agent, mortgage broker and insurance agent. Then have a checklist of what these people ought to know and what information they should be giving you in a timely manner without prejudice....without prejudice in this case means commentary should be given without pushing their product...whether it is a house, loan or otherwise. You only want qualified professionals who give unbiased information to help you unique situation.
