Last 3 deals have gone south - What is wrong with todays buyers?

[Account Closed]

IMO, When it comes down to money, todays buyers are either, unaware, ill prepared or indifferent to the requirements needed to close on a house.  While on topic, I throw many agents and loan officers into that bucket as well.  It seems many professionals just throw folks into the mix and hope all will work out.

I believe I am going to have to buy/fix/finance most of my homes because the holding time seems to be rising all the time, maybe from dumb anti flip laws, second appraisals or folks not doing their jobs. 

What have you folks done to keep enough cash on hand to buy, while waiting to cash in on currently listed inventory.  I guess I am thinking that today's need strategy is to make less on more deals than the opposite .
