Advice on putting multiple modular homes on rural acreage.

[Anna Christie]

I am in escrow for 20 acres in rural northern california. The property has power, well, and passed perc test. I intend to put a modular on it for my primary residence and would like o add a couple tiny homes or another modular as a rental. Does anyone have experience with modulars? Any recommendations for companies to work with? Anything I should be weary of? Any information is appreciated.
