Like not being able to say the house is a split-level or a bungalow or craftsman.By not being able to say a neighborhood is quiet or rough, it leaves the consumers (that the 'law' is meant to protect) more in the dark.

@Trenton MillerDepends on whether your target is regular consumers or investors.

All the time we hear from consumers that they think we misrepresented the size and we just put it back on the government.

Fair Credit Reporting ActA consumer protection law that regulates the disclosure of consumer credit reports by consumer/credit reporting agencies and establishes procedures for correcting mistakes on one's credit record.fair market valueThe highest price that a buyer, willing but not compelled to buy, would pay, and the lowest a seller, willing but not compelled to sell, would accept.Fannie Mae (FNMA)The Federal National Mortgage Association, which is a congressionally chartered, shareholder-owned company that is the nation's largest supplier of home mortgage funds.

May also consider a mechanical meter in case I am ever concerned who is using all the water.If you are looking for resources on how to charge it back look at the MN AG Landlord/tenant handbook.

Anyway, I've been going through the Hawaii landlord-tenant handbook, googling, searching BP, etc. and haven't been able to find the answer to this. 

This is a more time consuming process because time and work needs to be done to fix up the home and money needs to be invested into rehabbing. 

And that's probably to do with it being customary vs actually that time consuming...

There are more billionaires now than in 2016 so it would be time consuming for me to determine what percent of them had significant RE holdings.The top of the billionaire list is full of entrepreneurs as you indicated but in 2016 just over 10% of the billionaires had significant RE holdings. 

Profit has to be made in order for those products and services to continually be offered, improved and consumed.
