Real estate transactions involve one of the biggest financial investments most people experience in their lifetime. Transactions today usually exceed $100,000. If you had a $100,000 income tax problem, would you attempt to deal with it without the help of a CPA? If you had a $100,000 legal question, would you deal with it without the help of an attorney? Considering the small upside cost and the large downside risk, it would be foolish to consider a deal in real estate without the professional assistance of a REALTOR.
