After one summer of STRs I came back in the winter took a first lean mortgage on the property to replace the roof (and build my RV which I plan on living in while renting in the summer).

You can offer to lend the seller money to stop the foreclosures. 7 or do a lease with an option to buy - making up the back payments that would be considered you advance lease payment.Always look at the property if you have intentions of bidding at the auction (this can be tricky because you need to do that with the owner's permission - do try to build a rapport with seller  - also look at the foreclosure suit to find out what the bank is looking for and if there is a second mortgage or other liens.At the court house steps when the auction take place you need to be well prepared with your certified funds but more importantly you need to know the fast sale value of the property - you don't want to pay retail.Get to know your competition - there will be professionals at the foreclosure auction looking to capture some serious equity.

For turnkey properties (given your $20k constraint) it may be difficult to break even on cash flow within 2-3 years.

The best way to get started here (or anywhere) is to start by purchasing your own primary home because it's easier to qualify for the loan and it gives you a chance to build equity and you can purchase more house with a lower down payment.

Check your local building codes regarding what is required for an exit vent for one of these things.
