Doing it in one step is far less irritating.

I was happy to help the new buyer so the transaction would go smoothly but it was herding cats trying to get her the guest's info, pricing, respond to irritated guests who had to go through extra steps of rebooking with new owner, etc. 

There are agents and investors in my area that fire off incredibly low offers sight unseen and all they do is irritate the seller who then won’t work with you no matter what.  

A consistent and routine collection effort is known to get results if not completely irritate the heck out of this thief who robbed you of 7+ months of rent/damages.And, document everything to include that she abandoned the property and photograph/document the damages. 

And irritatingly, the answer is ... it depends.You have to do good work, using quality materials, you have to improve things that will actually add value ... and the valuation of your property has to be well-aligned to the current value.If that's the case, you can increase the value of your investment.  

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)!

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.

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.
