I try to keep well maintained properties and am in the replace with high quality components rather than slap dab patches that need to be redone every few months. 

Personally I think this is less of a detriment than having your note called and foreclosure.  

exciting time, Jared....I could go on and on, and the inspection will be key, too, but just first impressions: look at all the major systems and components and their useful life;that is key...

While the goal of affordable housing is noble, my experience has been that a not insignificant number of folks are abusing the system to the detriment of folks who probably really need housing.

Sometimes you can go to the BOH and get approval to replace the failing components if it is something like just a bad D-Box or something.Are you just assuming it will fail?

I don't tell them where I went to school or how long my company has been in business or any of that crap.There's an educational component to help in a seller understand all their choices.

Through case studies you will discover the steps and concepts involved in the cost approach-how appraisers estimate the cost of constructing a reproduction of or replacement for an existing structure; the three major components of depreciation and methods for estimating and allocating depreciation; and land and site valuation.

@Rene Martinez @Deborah Hill @Vincent Orobor As @Patrick Britton said, wholesaling "virtually" can be done, but it takes work and a few key components. 

Also factor in CapEx (expenses of major components that are depreciated such as new roof, new driveway, new A/C).

@Rich Harris another component you can look at if you are working with a Realtor:Have them do a  comparative market analysis (CMA) this can show you how long properties on the MLS have been vacant on the market.
