You need to step up your income ASAP. Are you a manager at Starbucks yet? That will at least get your income up until you can get something that pays more.
If you are going to go the agent route, try to find a brokerage that will refund your licensing classes upon close of your first transaction. A car that's not reliable is going to be tricky no matter what you do. Uber is a great idea but check with other Uber drivers in the area to find out how much they make on average. (You could be an Uber driver AND something else... actually, if you are looking to move forward working a standard 40 hrs is not going to cut it - you got to be hungry!!)
Go to the REIAs in your town, get to know people and let them know you are hungry. You want to learn and need someone to take you under their wing. Look for jobs with wholesalers. What if you switched from your Starbucks job to being a personal assistant to an investor.
Maybe look for people who are trying to grow their business but are working full time. (Just thinking of my own personal experience. I would not have been able to grow the way I have in the past year if it wasn't for my personal assistant and systems. She's thrilled because she's learning a lot - and I get my stuff done. Plus she makes a mean tomato sauce, so there is that...)
The thing is, although you don't need that much money to get started, no money is really hard. (I know, duh right?) Being an agent, you are going to need to take people around in your car and you may not get a sale for a while. But if you work hard, you can do it. ... especially if you serve a niche market like investors... or out of state investors. You could be the "boots on the ground" for them if they invest out of state... Think sale, construction mgt, then property mgt, etc.
If you're going the wholesale route, you are going to need to get aggressive. Drive or bike neighborhoods. Find the crappy vacant houses, look them up on assessor's website for owners. Contact them and see what they are looking to sell their house for. (don't use Zillow it's pretty far off for comps). With no money, you need to get creative. Maybe even partner with an investor - tell them you will do the contacting of the leads and close them and then hand them over. You get maybe every 4th lead to sell yourself or you get a flat fee or % per house that you are able to close and get under contract.
Again... it's just being creative, resourceful and jumping out of your comfort zone.
Good luck and enjoy the journey!
