plus for infrastucture and that is flat NO DIRT being moved just underground and paving . sidewalks go in by each lot owner.  

By default depreciation is straight line taking a flat amount per year based on the expected life of what you are depreciating.

We're also flat fee. 

@Gisell Garcia I've used apartments.com, which is currently free and ERentpayment.com, which charges $3/house or $10 flat fee.

That is why value creation and upward increase of rents is important.This is why I do not like Dollar Generals. 15 year flat rent and an inferior building in junk locations.

I've found you can negotiate a flat fee service at a slightly higher cost if you prefer consistency of cost over the risk.Fees - not typically large but transaction and back fees can add up in to the hundreds, if not thousands depending on volume and plan type.Income - additionals.

For instance where my project was  Lennar was only paying a flat fee of 5k..

So, as a matter of practice, I would always include those utilities in the rent if they are a flat fee utility such as garbage.

Typically flooring guys charge a flat install per square foot and then more for stairs.
