I would think you would be best demonstrating what you have done in the field as a more or less self employed real estate entrepreneur.

Instead of thinking about how many properties you want to own, think about what you want out of the properties that you own (most of us want cash flow but others have a more altruistic reason for investing in real estate).  

I originally was going to look for the office with the most training available, but literally all the offices i have been to offer roughly the same amount of training according to the calendars they gave, so that has kinda confused me in regards to what next to look into...Right now the top 2 based on how i felt after talking to the brokers are Berkshire Hathaway and Florida Luxury Realty...Berkshire Hathaway from the beginning seemed like a more cleaner operation, since both offices i stopped into had that new home feeling and presented very professional.

Having this in mind, I'm having a hard time deciding if I should purchase a more expensive (160k-190k), new property Triplex (built within 2 years or purchasing a property that is cheaper (120k-150k), already tenanted but it is only a duplex.

This year has been a more challenging year for us.  

Part of the reason she is having trouble selling it may be because it's not financeable.I think the idea of getting it under contract and flipping it to a more experienced investor is a good idea.
