Try this, maybe this sounds crazy but I know it works:
Step 1) Buy a map of your city or town
Step 2) map out where all the "Big Box" stores are, or shopping malls.
Step 3) Make up some weatherproof cardboard signs saying "I buy houses" and include your phone number and or website.
Step 4) Post them anywhere you can get away with it near the main entry points and exits to the big box centers. Here in my city those get about 100,000 cars going through per day.
Step 5) When you start getting calls have a questionaire ready to qualify the house. Especially the reason for selling, and to find out if they're willing to sell below market value or with exceptionally favorable terms. EI they'll lend you the mortgage because they own the house free and clear. Or theirs a death, divorce, bankruptcy, or other urgent need to sell below market value.
Step 6) Go to the bank and tell them you just bought a home and that you need a line of credit to do the rehab. If that doesn't work then maybe you don't need to spend a ton of money on the rehab anyway. Just buy some paint from walmart for cheap paint the inside and outside. Go to an "end of the roll" discount carpet center and sign up for one of their "store credit cards" so that payment is deferred for 6 months. Buy the carpet on the CC which you'll pay for later from the proceeds after you sell it.
Step 7) New paint inside and out, perhaps new fixtures and new carpet and lino. That will make about 90% of the house look brand new and your out of pocket expense was $100 worth of walmart paint.
Step 8) Now list it with a "flat fee realestate company" on the mls. Be sure that they are one "flat fee" for listing it. Also post signs directing people from the major arteries to your home for sale. Have a website for the house with photos so that people can do a virtual tour. Put that on a nicely made brochure which you can make with your computer printer.
Step 8) Sell the home, use part of the proceeds to payback the bank and the instore credit card for your materials for the rehab. And then do it all over again. Do that just 4 times a year and if you only made a sliver of a profit of say $25k you'd be making $100,000k per year. But infact you can usually do much better than that. I just made $140k net net on my last flip.
Step 9) Get started!
