2021 Prefab duplex construction costs

[Samuel S.]

Hey BP folks,

So I am looking to get a large parcel (30 acres total) under contract for around 5k per acre, and thinking that it could make sense to try and build ranch style side by side, prefab duplexes.  2 bed, 1 bath, 850 square feet on each side, $900 monthly rent. 

I have read a lot of threads on here regarding this topic, but seems like there is not a general consensus on if the multi family prefab model  makes financial sense.  I presume it's because it all depends on land costs, development/ utility connect costs, and rent comps.

My question is, if you take the above 3 cost elements out of the equation entirely, is there a standard cost per square foot anyone in this space is currently seeing, for just the landed construction costs only? And is there a key manufacturer who seems to be the most cost competitive in this space?

I think this area is only going to grow in the future, but wondering if we are still a ways out in terms of manufacturing efficiencies.

Thanks in advance!!
