On one of my new home developments here in Oregon I paid a construction Risk manager a flat fee of 15k.. to over see the underground process..

After the cost segregation study was performed, this was the new asset allocation breakdown by useful life.Here are some examples of what types of assets are included in each of these asset classes.5 Year Useful LifeSpecialized equipmentCabinets and countersRefrigerators and microwavesSecurity alarm systems and telephone connectionsDecorative wall treatments, ceiling fans and flooring15 Year Useful LifeSidewalks, landscaping and asphalt pavingSignage and site lighting39 Year Useful LifeDoors, walls, roofing and windowsFlooring, drywall partitions and ceilingsEmergency lighting and restroom fixturesPlumbing, HVAC, and electrical distributionThe use of the accelerated depreciation strategy helps real estate investors to reduce the tax liability immediately which therefore increases their bottom line due to the offsetting of income.

Are there common roofs?  

They needed a new roof and the guy quoted my friend over 4x what it should cost. 

not needing a roof and an HVAC system and maybe some electrical and maybe other things.

Find a qualified agent willing to work only on a flat fee to write up the contract and other legal requirements.

I am building a vertical addition above the existing main level which would have vaulted ceilings OR alternatively the front half would be vaulted and rear where the bath/closet is situated would have flat ceilings with rooftop deck above.    

Thank you would it cost more then 200,000 to just do the basics like, insulation, electric, roof and plumbing?

For saving a couple of hundred dollars a year we gain the "privilege" pay $1K-3K in general  deductible and $4K-6K in hail/wind deductible (and likely 80% of the cost of a new roof here in TX).

Reno consisted of gutting and replacing the kitchen and bathrooms, replacing the floors, light fixtures, HVAC and roof.
