Hello, Kkopelmn, I would agree with Patrick that the first order of business would be to find a buyer's agent that you are comfortable working with. Most of your questions have been answered by others below so I will offer this additional information as food for thought only.
Typically an attorney is not necessary on most residential sales unless the situation falls outside of the promulgated forms Texas Realtors are required to utilize in making these transactions. I have not encountered such a situation but it is always possible. Any Realtor would recomment an attorney should the situation warrant one as it is outside of the scope of our license to render legal advice. I would think this to be true even in Maryland. Most transactions are handled by a title company's loan officer through the title company and settelment is made. Choosing a reputable, long standing title company is as important as well.
