Remodeling Houses

Hi, I seeking for advice. This is what happened to me: I used to have excellent credit 750 I bought a foreclosure house and made 35,000 profit in 1 year. Then I bought another foreclosure house that was fire damaged and I put a lot of money to fix it. Since I spent all of my money a used my credit cards to fix it. That's how I get into debt. The house was beautifully fix and upgradded. But, the market started to fall and the loan that I got for that house was not a good deal. I refinanced the house to pay my credit cards but my credit score got lowered and my new payment higher. I sold the house 2 moths ago and only made 11 grand profit, wich I used to buy a 3 unit apartment building (that was a bargain) but I'm using all of my money to remodel the apartments and nobody would lend me money for the repairs until I make 6 month payments on the mortgage. I want to get it done before the winter. I had almost max all of my credit cards and still need more money. I'm even considering one of those non for profit organizations to deal with my creditors. is that advisable? Plese, let me know what should I do. Thank you
