If you're an agent I would recommend starting small and buying some properties in your immediate area, so you can view these and sell them your self obviously.
Be prepared for expenses such as taxes etc.. on these and this should factor into your decision of how many to buy. Also the avg # of days homes sit on the MLS for your market should factor into this as well.
Some investors prefer to buy MFR buildings/units so that they can set up managing companies to run these from a far. So that is another strategy
Many investors buy these kind of deals only to have properties spread throughout the country and did not ask the question that you asked. And as a result dont profit as greatly as they should, or actually lose money as they cut losses
I have never bought a bulk tape before but have been aiding in selling these for a little bit now. So know your resources and have a plan as all investors should and you will be fine. Please let us know how your venture goes if you decide to move forward. Good Luck!
