To answer your question I've never counted, but over the many years this seems to be something that pops up, along with missing furnaces, and missing hot water heaters. 

@David C.About once a year, I post about finding some absurd amount of money inside the wall of a foreclosed house or behind a water heater in a dark basement.

Your agent should be able to show you numbers of recent properties that were a "good deal" based on market standards. 

Water bills are up 50% to 100%, electric bills are up 33% and gas bills are up 30%, and of course tax bills are up and new bills for new items are created. 

My current favorite is to use the standard contract realtors use in my state of Arizona.

I can break everything down from NOI, standard operating expenses, and cap rate to assisting with an exit strategy. 

But if you sit vacant for one month before finding a tenant, you've lost a month of rent and utilities and earn only $16,350.On the other hand, if you drop the price $100 and find a renter quickly, you will earn almost $500 more in that first year.Always remember: lower your price, but never lower your standards!

The bottom 1/3 of our population has to pay with a lower standard of living until????  

Then if 50% of bookings actually use the "included add-on" with a standard $100 coupon, that's $2000 in services I have to fulfill (for now I'm assuming they all use the full $100 but I'd set it up where it's a discount code and I charge for any extra amount).
