Hey @Minuit Spence, I hope things are going in the right direction for you.
As others have already stated, your primary focuses should be improving your financial literacy through self educating while at the SAME time, looking for ways to increase your income and decreasing your expenses. Improving your credit score will make things a heck of a lot easier for you moving forward. If you plan strategically, there are ways to do all of these things simultaneously.
With regards to investing in Real Estate, you will need a minimum 580 credit score for an FHA 3.5% downpayment loan or 620 credit score for a Conventional 5%-20% downpayment. If you can get your credit score up even higher, you open the doors for qualifying for downpayment assistance programs. Most programs will require minimum of 640 credit score to qualify, although some prefer you have a 680 minimum credit score. The programs usually require a minimum cash contribution from the buyer such as $1000 while also completing a First Time Home Buyer Educational course (the course only takes a few hours and can be completed within a week).
I strongly recommend trying to acquire multifamily family (2-4unit) properties as your first purchase. Qualifying for a loan for a multifamily is actually easier than a standard Single Family Residential property because the lender is allowed to include up to 75% of the gross total rental income as income that will offset the mortgage payment. For example, a buyer who currently qualifies for a $250K FHA loan for a Single Family could also qualify for a $500K Quadruplex if the rents are high enough to offset the mortgage of a $500k loan. In my area of Atlanta, FHA loan limits are $380K for a SFR, $485K for a duplex, 587K for a triplex, and $730K for Quadruplexes. What does this mean for you? It means you and everyone else is capable of owning extremely valuable real estate for 3.5% down while cash flowing exponentially, if done correctly.
Next, I recommend obtaining a real estate license. I got my real estate licensed 3 years ago when I found out that I would be getting paid the commission when I purchase my own investment properties. The standard commission rates paid on purchases is typically 3%, although there are purchases that I've received 2% on and even a purchase that I received 4% commission on. Imagine combining this with downpayment assistance. A real estate license for an investor is almost invaluable. It is 100% possible for you to obtain a cashflowing multi family and walk away from the closing table with several thousands in commission and have a place to live, rent free while you owner occupy 1 of the units (Most feasible when done with purchasing Quads and triplexes).
Just persevere and grind towards your goal. Plan accordingly, and you will make it out of your situation. I'll see you at the top.
Best wishes.
