Foreclosure searching questions

[Adam Fleming]

I am new to bigger Pockets.  I am trying to navigate the page I hope I am posting this question in the right place.  Aim trying to get my first flip.  I recently just bought a house and two lots.  I am working on rehabbing it while I live in it.  But meanwhile I am trying to educate myself on private money lenders and hard money lenders.  Also trying to learn the calculators so I can use them and be fluent with them.  I know i need to run through at least 20 or 30 properties and check them out run the numbers and get good at evaluating theses houses.  But the problem is all ready owning a house, rehabbing it, membership fees to every site that involves real estate can get expensive quick...  I always hear about people being frugal,  will someone show me the fugal way to find foreclosures.
