Is this your first purchase? Even if it is not, I highly recommend that you hire a licensed real estate professional to assist you in your search. It does not cost you since it is the seller that pays the commission but, he or she will work for you and will be your advocate during the process.
Purchasing a property is one of the most significant investments that anyone will undertake. When you attempt to do it on your own, you are actually undermining yourself by not having a professional that will guide, protect and work on your behalf while the seller pays their services. If you have a toothache, you go to a dentist, if you have tax issues, you go to an accountant, a legal issue you hire an attorney....you get my drift.
Interview some agents and find the one that you have a rapport with. We all have access to the same listings. It is the way we approach the search and care for our customer that differentiates us.
