No Nathaniel, not all the houses listed on this site are scams. However, you should keep in mind that there are certainly some less than honest homes and rentals etc. which ARE scams.
My advice to you is to NEVER offer out your personal banking or financial information to anyone over the phone or internet. No licensed real estate agent is going to claim that he or she is currently out of town and therefore cannot meet with you but would still ask for your financials (at the home howners request). Be certain to physically meet with a realtor to preview a home or apartment in person. Only then, should you proceed to legally pursue a property. If you require any additional information or assistance, please feel free to contact me at your convenience. I look forward to assisting you with all of your real estate needs.
Best of luck!
