I would suggest getting pre-approved for a mortgage to start, so that you know what price range you can afford. That way you can also get a handle in understanding what the costs are for buying a house in Maryland.
Also, since you are a first time buyer in Maryland, you may qualify for a number of different down payment assitance grant/loan programs which can give you a little more flexibility in the purchase price. I discuss these type of programs at length in my blog: http://www.ThoughtsAboutRealEstate.com
If you would like to get pre-approved for a mortgage and find out what types of programs you qualify for, please feel free to contact me. But whatever you decide to do, Welcome to Maryland!
