We are in the middle of the remodel, and have had some opportunities to make sure of this. 

My parents are looking to remodel their old triplex and rebuild it into a four-plex.

Thanks for all the replies....I think my mistake in the logic and looking at all those sites is just how you kind folks have pointed out..... being  that I won't be a typical homeowner looking to redo a kitchen or bath....so using those remodeling guidelines would be a mistake ......I appreciate the helpBruce

I have experience working on a wide range of residential projects, from small kitchen remodels to custom homes, everything from $50 per sq ft to over $1000 per sq ft.

@Brandon Pelfrey - I have purchased a duplex that was completely remodeled with almost everything being brand new.

Business Start Up Expenses are intended for things like market research, consulting with lawyers and accountants, researching business locations, etc before actually going into business.Remodeling expenses are remodeling expenses.Also, no ad in the world is going to save you from the "Asset in Service" rules if the property is not actually habitable.
