現金管理结构：分四份買4-weekT-bill，每隔一星期到期，自動Roll。一份放在bank。內看例子。

example:

$10000 in bank

$10000 4-week t-bill due one week, auto re-invest

$10000 4-week t-bill due two week, auto re-invest

$10000 4-week t-bill due three week, auto re-invest

$10000 4-week t-bill due four week, auto re-invest.

Link Bank account with Treasury direct.

Feel free to replace $10000 with $200000 for a total of $1 million cash.

In that case, one can make cash offer for a $1 million property that closes escrow in one month. 

Or cash offer for a $600K property that closes escrow in 2 weeks.
