toward higher interest rates, signaling that it remains on track to raise
its benchmark interest in December for the first time this year but holding

After a two-day meeting of its policy-making committee, the Fed delivered

发帖数: 1098 | 4 市场上作mortgage的鱼目混杂，大致分两种人。（这样说mortgage的人会不会半夜敲我
家玻璃）
1.Bank 和local Bank
Bank的人自己有审批权,所以会快一些。住condo的要找这样的主儿。你的condo在
broker手里不动办不下来就是这个道理。夹了broker个二道贩子在中间，选的银行也有
限制，像owner占用率。买foreclosure的房子的同学就只能找local Bank了，因为他们
胆子大，限制少，敢把钱借给你。
2.Broker
像你回国买飞机票一样，明明不喜欢agent也离不开这些人，因为他们拿的利率你拿不
到。所以broker的人品很重要，如果他一定要赚到八千才收手说不定就给你错过了最低
rate。如果你找了两家，第一家锁了，第二家答应的rate再低（只能是自己赚得少）他
在同一家银行也锁不上了，同一家银行不能下调也是这个道理。所以一定想好了再动，
broker手上的loaner资源rate低的就那么几家，相差无几。
我的rate不是从Bank问来的。

An irregular heart rate, or arrhythmia, can be caused by many different

disease. Experiencing an irregular heart rate only during or after exercise
may be a sign of a very specific and life-threatening problem:

以减少一点overhead rate。每个公司都不一样，具体进去了就能感受压迫的程度。所
以，做出选择的时候光比工资+benefit是不够的，还要考虑工作强度和公司氛围。
大公司通常overhead要高些，养了一堆有用又不干活的人，例如从政府退下来的，客户
的亲戚，marketing，accounting等等。URS overhead rate据说比较低，估计不到150%
，不过对员工的billable hour %就比较高些。小公司按常理overhead要低些，可是如

有时你工作了那么多billable hour，但是firm不一定都向客户报，或者向客户报的时候
把rate打个折。你是喜欢给自己记打折前的还是打折后的呢？要是有的associate因为做
的项目打得折扣比别的人多了，那岂不是要多干好多时间才能赶上人家带给firm的reve

还有，随着你每年工资的增长，你的hourly rate也是要涨的，基本上工资与你的hourl
y rate的增长成等比关系，所以撇去这些直接看billable hour就能看出你在firm里的价
值了？
最后，有些所不公开billing rate，但是又要告诉想来的人你得做得多卖命，那就只能
