You need to identify the components (I.e. roof, A/C, stove, etc.), estimate the remaining useful life of each component, estimate the cost to replace each component and then determine the amount you need to set aside each month for each component over each component's remaining useful life expectancy.

The cost of remediation is only one component.

Without the last component, the opportunity could actually hurt more than help.

We're putting in mid-to-high grade components and are appealing to a younger buyer (newlyweds with child coming in the next year or so) and quartz seemed more targeted to a younger demographic. 

To answer your specific question though about who to call - there are companies that specialize in duct cleaning - they may be stand alone operations that focus on that, or a smaller component of a larger mechanical company.  

It seems like most successful operators have mgmt as a component of their operations.  

They can't seem to be bothered to put the building SF in the listing, they all try and control the conversation to the detriment of their client--the seller--in an attempt to build their lead list of buyers--i.e. they won't give me additional info on the listing without more info from me--that can not be helping the seller's position!

Originally posted by @Derek LeBlanc:im just trying to find an easier way to estimate repair costs. i am no contractor and have no idea how prices run. i went to home depot to look at prices of things but that comes nowhere close to what it would cost for installation and everything..so how do i figure out repair costs if i have never been in constructionYou're looking for shortcuts and there are no shortcuts when it comes to estimating (at least not at first)...In my opinion, the best way is to break the rehab down into all the major components and then break the components down into specific tasks. 

@Ming Lim We aim to establish and maintain a reserve of between $300 & $600 per unit depending on the building and the age of its major systems and components.
