It's part of the game, it's exhausting, draining, and sucks the life out of you..  

Sometimes you just get one that is EXHAUSTING!  

Once that's exhausted, go to the next lowest down payment option and the next etc... until that's exhausted and then do the next.All of this means you'll be moving quite a bit, but if you're gaining rental properties (I would certainly buy units at this stage of the game), and the properties are close to one another, why not?

Major players with low cost of capital can play the low-interest game as well as perform more exhaustive research on additional unpaid taxes.

Exhaustive research.  

Shawn Ward best part about cash (why a lot of big flippers use it) is two fold:Helps you get propertiesAllows you to withstand setbacks on a project (which usually happens) without getting killed by those additional interest payments.

I was exhausted by the time it was done. 

Everything said in this forum not withstanding, it is all opinion.
