I'm using the MLS to extract the data.

It's simple really.If going to a seminar and paying money will take MOST of your net worth then don't do it.People think these classes are the silver bullet to getting rich.Then they get mad when it doesn't happen and they are almost broke.I would say in that case KEEP YOUR MONEY and do mailers for leads and read FREE material in books and on the internet.Find local investors you can learn from where you want to do business.If you are making money at substantial rates and want to pay for a seminar then it won't be the end of the world for you if it doesn't pan out.It's no secret that many companies will get people at the seminars to "source deals" for them to partner on and use the fees from seminars to buy more properties and get richer.It is NOT for the benefit of those attending the seminar.I do not know this company and I am speaking in generalities.You can find these systems for 30 cents on the dollar usually selling for resale on Craigslist,Ebay,etc.When I bought a broker course on generating listings first getting into real estate the regular price was 997.00.I went in with another broker and bought a used one from the same year on Ebay for 300 so we paid 150 apiece.A year later I resold it once extracting all info for 250 to another broker.So if you are great at and enjoy sourcing information you can do it for cheap or almost free.If you want it in a nice little package you will pay heavily for it.A common tactic of seminars is to throw almost all the "meat" out there and then when you buy the course it just resays about 80 percent of what was already said with a lot of fluff thrown in.

You could try to extract equity in the form of a HELOC but that presents it's unique risks if you have a floating rate. 

-Extract your equity through a cash out refinance of your existing property-Get a home equity line of credit -Sell the equity in your home to a company like Hometap-Use the equity in your home as collateral on a loan from a private investor -Get a low interest credit card that is secured by your home equityAll of these options still require a healthy down payment and a good deal with returns that are above and beyond your cost of capital so that your debt is levering up your profit vs levering up your losses.

Also, it’s not just “70 bucks” because those unethical agents who manage SFR part time extract more than management fees on average.  

What do you think the cash flow would be on the average San Francisco property purchased in 2000 if it never had value extracted? 

Clayton is such a piece of crap lol.It's a fairly easy country to do an extraction though.  

As an appraiser, I extract adjustments for other factors such as location, parking, etc. to determine the market's reaction to these factors.

You can extract frequently asked questions from prior inquires, and compile them into a document that you can share with your VA.  

When those specific nuisances are cleared, that can remove the impediment to value creation and prices shoot up.As for value extraction from this process, you can do your piece to help it along by buying a rental with an eye toward long-term price increase.
