Is it worth it to invest in new builds that were never finished?

[Sarah Parkin]

I'm new to investing and BiggerPockets, and am interested in rehabbing properties. I'm still in my research phase, and have done quite a few potential home walkthroughs.

Question for the ranks here... is it ever/can it be a good investment to purchase an unfinished new build, finish it up, then sell it? I've come across two SFH in the DC area that are very nice/brand new homes that, for whatever reason, were never finished being built. My first thought is permitting issues. But that aside, can this ever be worth it?

Both homes are finished entirely on the outside, have framing, plumbing, and electrical completed. They still need drywall, flooring, kitchen, bathrooms, etc. Would you have to hold the property too long to finish all this to actually turn a profit? I'm not sure how much time this would all take...(one home is 3,100 sq ft, the other is around 10,000 sq ft).

Thanks for the help/advice!
