It is actually a feature in top property management software.

When updating bathroom plumbing and it doesn't need a full gut I don't try to salvage the tiles I make it a feature always looking to add character to my spaces. 

That is a nice feature.

I seen zillow has a new 'zestimate' feature that predicts what an REO is 'Probably going to sell for' before it even gets listed!

Let's start with a good ARV, estimate repairs/updated features, and then work the numbers.

So only those pads with existing cement will be able to offer this expensive feature.

Unfortunately these projects often features the homes jammed up on the property lines with a complete obliteration of existing trees/landscaping features to make rooms for a monster house so it doesn't necessarily serve to 'upgrade' the neighborhood in many cases other than increased comps.In other areas I've seen a builder slowly accrue multiple lots of and develop them in a more tasteful manner with new construction that is architecturally consistent with the other new homes they've built adjacent and allowing for proper landscaping.I try to do everything I can to avoid complete teardown and rebuild, if I can utilize the existing foundation and utilities it is a huge cost savings both in construction and in paperwork and permiting.

@Emily Powell - use the Connect feature and send me a Colleague Request with a brief message, and I will send you info that I sent to @Alex M. 

Have there been any additional features, have existing features been upgraded?  

Is is this gas option a feature you advertise?
