It might relate to the purchase, NOI, and gross selling price (so-called unlevered IRR);  or it might use the cash invested, the after-debt-service cash flow, and cash proceeds from sale (so-called levered IRR).It is worth knowing the capitalized value of the NOI since that presumably is what the property is "worth" today, and it is the value on which a lender will probably base financing.

Irritating, self-absorbed jerks are not a protected class (yet)!

Chasing returns on someone elses word is sure way to catch the dreaded lotto winners flu.

I'd be irritated I were them.

There are 2 issues...1) you will irritate even the nicest inspector and 2) you will most likely cause him to miss a few things.

The Avian flu is not helping egg prices right now for example.For example, the past 3 months Core CPI minus Shelter is -1.0%.  

Los Angeles wants to extend it another 6 months because we're in flu season.

As for payday, your 4 day window would be fine by me, its when I get up to 10 or more days disparity that I start to get a little irritated. 

I'd be very irritated if my realtor EVER told me that an offer I wanted to submit would waste everyone's time.

(irritating the judge will never help your case.)
