There's lots of other ways to acquire real estate besides the un-creative, boring way of using all cash.
If you're trying to buy equity at a discount (that's really what a super-bargain is) then rethink the way you try to buy:
Using $100,000 ARV for simplicity sake - Buy subject to existing mortgage (example)
$50,000 - existing loan (take over)
$3,000 - cost to cure back payments (cash)
$2,000 - back taxes (cash)
$10,000 - Fix up
Now, seller wants something for their equity. You want something for your effort.
There's a $35,000 gap here. How are you going to fill it? What can you give seller that gets them what they need and you gain something for your bargaining effort, capital, skill and expertise?
You could give seller a purchase money note. You could give them cash plus a note, all totaling $10,000 for the equity. Or a car, boat, free rent, a vacant lot that you don't want; most anything can be used in the trade.
If you become skilled at this, you'll haunt garage sales for things to buy, trade and use as equity stretchers.
You don't need more cash. You need a willingness to learn how to make deals.
