The challenge for me will be to attempt to mirror this type of financing approach to Southern Calif. real estate. 

Personally, I've had success in Linden, Southern Orchards, South of Main, Driving Park, and Franklinton to name a few neighborhoods in Columbus. 

Quote from @Suganya Vinayakam: I'm currently constructing an ADU in Southern California.

Either way you chose to go I would definitely recommend the southern/middle part of the country places like Texas, Tennessee, Arkansas or Oklahoma.

Hi @John I'm based in Southern California, but I have started my out of state real estate journey in Indianapolis.

I currently live in Southern Maine and am looking to construct some kind of new project rather getting into rehabbing existing residentialProposed Land Budget 100-200kConstruction Budget: 400kAll in 500-600k.I have found that if I do the site work myself including clearing, septic and digging the foundation is that i can sub contract out either steel or a Lester style building (50x150) for around 300k installed with insulation and power , divided into three 2500 square foot units. 

They prefer the middle/southern part of the country because the laws are friendly and prices are more affordable.

This is in Wisconsin and I'm in Southern California.

They sold two appreciated duplexes in Dallas and we turned them into 8 units in Mesa, AZ with higher cash-flow, and much closer proximity to Southern California.I'll add to your Phoenix "pros" list:1) Landlord friendly rental rules2) Easy evictions in < 30 days3) Rents are rising faster (on a % basis) than many other metro areas4) Low property taxes (and the property taxes don't sky rocket after a purchase as they do in CA)5) Very low vacancy and extremely high tenant demand.

Im someone who is interested in investing in southern westchester area.
