I have 1 paid off rental house, but the A/C went out during the summer months and I went ahead and replaced it along with the old furnace, and new roof... that cost me money so now I'm back to square one
I have an IRA and just started a company 401k. If I'm still working for this company 4 years from now they will match $0.50 on the dollar (unless they can that).
I occasionally buy broken down cars via craigslist and fix them up, drive them for a month or more, and re-sale them for profit. I can only legally limit this to 5 a year since I don't have a dealer license and do not wish to obtain one. More of a strange hobby than investment, but I did sell a Ford Contour for $2,900 a couple months ago that I purchased for $800 and put about $280 in parts into it (timing belt broke, and needed brake work).
