Advantage/disadvantage of getting sales person license

[Harish V.]

I am a do it yourself investor. Mostly single family home, buy and hold as passive activity. I was considering getting a SalesPerson license, mostly to allow me flexibility to

1. Write my own offers

2. Flexibility of not calling another agent if i want to see homes.

3. Use depreciation losses to offset the income - overcome limits of passive activity.

Any thoughts on disadvantages?
