Don't give up if it's what you really want.
You can look for someone with the credit and money and you supply the work and hustle. Head to all the meetups you can get to, you're in Houston, gotta be tons there.
If this doesn't work then just take some time and work on your credit score and save everything you can from your paychecks. A defeatist attitude definitely won't help. Gotta stay positive, have a plan and work hard on that plan and I promise you can and will make it happen.
Also, surround yourself with positive successful people (this may mean you have to remove negative and cancerous people from your world, ouch) and start or maybe keep listening to productive podcasts (Bigger Pockets, Gary Vaynerchuk, Grant Cardone, etc...) and reading all you can to understand the process and educate yourself.
Keep your head straight and you'll make this happen just like you did when you got your CNA.
Sorry if this comes off as sappy or preachy but you CAN do this!!
