Seeking Duplex/Fourplex Builder Recommendations and Rough Cost Per Sqft

[Michael S.]

Seeking recommendations for a duplex or fourplex builder in the Phoenix area and the construction cost per square foot.

Four years ago rough estimates were at $100 sqft, now I'm seeing about $200 sqft with another $50K for site preparation.  Most of them are estimating a construction time of 12-18 months.

I have a few homes that are on large lots that should probably be further developed to maximize return.

Thank you

I listened to a BiggerPockets podcast at least 1.5 years ago with a lady from LA who knocked down houses and built large 3-4 bedroom 4plexes. The interesting thing was that she built them with modular/prefab construction. The walls came assembled with the plumbing in them from the factory, and then they craned them into place. The building time was much faster! You might look into something like that.
