Tamja, unless the house is selling for $40K, $20K in " equity" is no big deal. Buying a $200K house that needs work for $180K is a guaranteed money loser.
So, I have to reemphasize the point other posters are making. You need to get educated. If you're looking for someone who will teach you all the ins and outs of this business, then you need to go to some guru's $5000 boot camp. There are plenty of those out there, and for that money you will get a good education. At least in whatever area of this business that guru targets.
If you want someone to explain it all to you in detail for free, then its just not going to happen. Its a complex business, and requires a lot of time.
If you are willing to put in the effort, then you can learn this business without spending much money. You can do some reading here, for one thing. There are lots of knowledgeable investors who have been doing this for a while and have great insights. The best part is they share those insights freely. If you do some reading you'll learn about the 70% rule for purchasing. The 50% rule for expenses. Wholesaling, rehabbing, subject to, hard money and all sorts of other topics. Read the deal analysis forum and you'll find deals, good and bad, that people have put up for examination and that have been analyzed in detail.
There are also numerous, numerous books available. You should be able to find some in your local library, if money is an issue. Or browse through them at a book store, and just buy one at a time.
If you're never bought a property, buy a " first time homebuyer" book. That will explain a lot of the basics of the buying process. Those are largely the same for investments as for your own home.
As you read and study, you'll start getting a grasp of the basic ideas. Some areas will appeal to you and some won't. Some will be feasible and some one. So, you'll be able to narrow your focus on the feasible and appealing areas, and dig into more detail on those.
As you say in your first post, this is a business. Running a business requires money. If you don't have any money, you better have good credit and income to support debt. If you don't have either, then frankly you need to get a job. I can't really tell what your situation is. There are some RE investing approaches, such as wholesaling, that require minimal cash. In wholesaling, you don't buy the property yourself, but buy it and immediately resell it for a small profit. But even that requires money for advertising to get your buyers and sellers. And a lot of time to close the deals.
So, bottom line, do some learning on your own. Be able to offer something to whoever you're partnering with. Be able to ask very specific questions. Then you will find people who are willing to work with you.
