There are 3 main components of the deal: Purchase price, Interest rate and Time.  

You depreciate the building the commercial building over 39 years but there may be segregation for large components like HVAC.

Managing these 3 components is the key to moving real estate.I hope this helps.

Real estate development has so many components.

For newly constructed, purchased or renovated properties and also retroactive generally over the last 10 years, building components are properly classified into individual units of property and accurate recovery periods for computing depreciation deductions.

I might not use a property that sold last year because its way too old for a comp. One

But yes, unless you have an end buyer FIRST, every other component in the transaction is a waste of time. 

Below are the basic components and descriptions of each.Location - The locations where significant percentages of the target segment are renting today.Property type - What type of properties are they renting today?

The components are so easy to install and remove i put them up when its empty and back in my closet when occupied. 

I'll have to understand more what the state of existing components are for this house in order to estimate this.
