I have about $300 on my credit cards (just finally paid them off for the most part, and have about $20,000 limit).My cash on hand is relatively light, but what my plan was was to find some single family homes in the north Detroit area (currently anywhere from $40-$60k and put about $15-20k tops into any repairs or fixes (not looking for total rehabs, mostly something I can do some small repairs here and there and paint, personally I am knowledgeable about renovating up until complex electric and plumbing).

And do it with a smile and energy unknown to most.
