no matter how many times I emptied the gutters of moss, they kept getting blocked again months later due to the moss falling off the roof into the gutter. we had the insurance guys come over to check it out and they recommended we get a roof cleaning company in every year and also one to do the gutters. after a lot of research we found out about the roof scraper tool from roofscraper.co.uk we bought this tool and then scraped the moss off. saved us a lot in recurring cleaning costs. the only thing is you need to apply a chemical after to stop the moss from growing back. these chemicals can be quite toxic so you must wear the appropriate safety gear!

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.  

Hotels use white because they use a bleach that is SUPER strong (much more toxic than we can get on a residential level and have maids use). 

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. 

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.)
