thank u for this post

Y O U have to make you a success.  

Zoning is the main issue, it is zoned U-SU-C which looks like there are no additional detached dwelling structures allowed.

experience, no book is going to give u the magic formula, sorry,,,,, your best bet look at a few properties with a contractor get an idea what they are charging for certain things in your market. labor rates are different per trades per area, material costs vary so on

where u at in cali.

Do u have to?

And my four kids are my world so there u are.

so basicly u are saying that someone teaches ya how to screw the bank so to speak?

go to zillow.com they have good comps but dont depend on the zestimates they give u on properties.

So would u say the purpose of doing so is to make sure that no one area of the town gets overly populated??
