Hi @Elan Adivi Welcome to Bigger Pockets. Just interacting here is a good practice and will definitely help you to move your investing career forward. It actually sounds like you have 2 different challenges here. 1) transitioning from a non-sales, W-2 job, to a full time sales job 2) beginning to learn about and invest in real estate.
These are both related to RE, but entirely different issues. If you go sales full time count on 60-90 days with little to commissions. You'll burn through any money you've set aside. You'll need time to get yourself established and start building your client base. Even if you did just this alone, without real estate investing, it is still an enormous challenge. Having your dad as a resource will definitely help shorten that learning curve and potentially help you generate some leads. Overtime, you'll be able to build some capital to use on a down payment for a property.
It actually may make more sense to stay in your W-2, and be an agent part time. It will be a lot easier to get a loan on a property if your income is regular and predictable. You can learn real estate investing in your free time. Attend REIA meetings and network with other investors. You can pick up some clients there as well. You'll get some deals under your belt with some decent commissions. Put that money away for when you're ready to buy that first property. At some point I think you'll have enough money put away that you'll feel more comfortable to be a full time agent. Good luck!
