How much rehab does a house need to be listed as new construction

[Emily Hosage]

My husband and I bought a house at auction in complete need of everything. Great neighborhood, nice lot, just a total mess. We are in drywall and finishing phase and have a ton of money sank into the project. We've completely gutted the place, full replumb, new electrical wiring/box/service, all new fixtures, floors, trim, appliances, doors, fireplace rehab, everything inside is new, opened floor plan, etc. New roof, siding, trim, new wrap around porch, deck, everything exterior down to the landscaping. We are still and projected to be profitable, but obviously we could list for more if we could list as new construction. I ask because of the level of reno and a project in the same neighborhood, that was also a huge reno, just got listed as new construction. We live in PA, just outside of Philly. Does anyone know of any guidelines or have any advice for listing a serious reno to get the max money for it? Thanks so much!
