Very interesting question, thought I may take a stab at trying to answer it using some data science.
I assume by your companies area you mean Hyattsville MD. The following is based on data for the entirety of Prince George's County.
I started by exporting data from Redfin using their download feature to build a dataset of 4054 new construction properties sold in the county since 2014.
Just by looking at this data, it's already clear that two huge demand drivers are property type and location (by zip code)
If we look at the median DOM (days on market) as our demand indicator and group the data by property type, we see that condos sell almost 100 days faster than SFR.
Likewise, by aggregating by zip code, it's clear that location has a major influence on demand.
However, your question was what features inside the home drive demand. So I decided to take the analysis a step further.
On each Redfin listing, there is a section titled "interior Features". This section contains metadata regarding what features each specific property possess.
To retrieve this data, I re-purposed a simple crawler I had written in the past and was able to pull into my original data-set all the interior features that Redfin tracks and whether or not each sold listing had each feature.
I then did the same analysis and came up with this:
High Res Chart Link
This chart shows the median DOM tabulated by properties that do and don't have an interior feature. I limited the analysis to features that had a sample size of 25 or greater to reduce error.
Of all the features, the ones with the most DOM difference were homes that had carpet, separate dining room, pantry, walk-in closet, ceiling fan, and sprinkler system listed as features included.
Some features correlated negatively with DOM, such as wood floors and upgraded kitchens. This may be because of the added costs that these kinds of features add to the final price, which also correlated negatively with DOM.
Hope this helps answer your questions!
