Here is a list of the 20 best ways to find motivated sellers - this should cover it :). It was posted on my personal blog.
1. Classified Ads in Newspapers - local paper, Pennysavers and local real estate publications ("For Sale by Owner".)
2. Classified Ads online - Craigslist and Backpage.
3. Search Classified Ads online and offline - look for houses for sale with "Motivated Seller" or "Must Sell" in their ads.
3. Vacant Homes - drive for dollars. Look for abandoned or vacant homes and locate the owners via Recorder of Deeds office.
4. MLS Search - expired listings, short sales possible, fixer uppers - these are all terms to search for.
5. BirdDog - these are individuals that will look for houses for a flat finder's fee.
6. For Rent Signs - especially if there are vacancies or are out of town owners, they will be motivated sellers.
7. Wholesalers - partner with them to locate properties and sell them to investors. They know where to look.
8. Preforeclosures - "Notice of Foreclosure" is published on the legal paper.
9. Divorce Filings - look in legal paper for divorce filings.
10. Probate Filings - look in legal paper and probate court.
11. Tax Sales - contact the City and County for tax auction dates.
12. Private Auctions - check online and local auctioneers for listings.
13. Foreclosure Auctions - check City and County for times and dates.
14. REO (Real Estate Owned by banks) - contact banks and MLS for listings.
15. HUD (Government Owned Properties) - check the site HUD.GOV for listings.
16. Networking - network with professionals (CPAs, Attorneys) and rehabbers/landscapers for referrals.
17. Bandit Signs - post bandit signs in strategic locations: intersections, Home Depot, vacant properties.
18. Business Cards, Flyers, Magnetic Car Signs - let everyone know what you are doing and looking for.
19. Website - a website targeting distressed/motivated sellers. Offer a Free Report like on techniques to avoid foreclosure and have the site optimized for your local market.
20. You the Investor - always have a positive and outgoing attitude, ready to meet people and network.
