Hi @Michael Vasquez,
I'm late to the conversation here, but, I think it's good you are NOT using your credit card and doing more research, especially if you just repaired your credit, and may have low limits and high APRs. Yes, there is an opportunity cost involved in waiting, but (pardon me if I'm wrong) it sounds like you are doing the right thing by educating yourself more.
You mentioned you found " a really nice property in a good neighborhood" for $12,000 AT FORCLOSURE, which MAY mean - that is the opening bid or judgement amount. It may actually be a good deal more. Plus, you need to know the After Repair Value (ARV) and the cost of the scope of work inside, to repair it.
Definitely attend that homebuyers seminar you mentioned, and also, do more reading on BP under the "education" tab. Especially, in your case, I'd recommend you listen to BiggerPockets Podcast #009, "Using Hard Money Lenders to Grow Your Business with Ann Bellamy."
I'm from Buffalo, lived here my entire life - send me a private message if you want to chat about your situation, foreclosures, or private money lending.
