Splitting a lot and developing

[Ted Hlaing]

Hi all, 

I am new to the forum. I have a home with 2.5 acre land in Sacramento county. It is zoned RD 5. I want to split the house out from rest of the land. 

I need suggestions on followings.

1. Should I just do a simple split ( splitting the house from the rest of the land. The house is at the corner)?

2. Or Should I divide into all available lots based on RD5 zoning?

3. I have some money to split but not for developing. Is there any local developer who will be willing to invest together?

Thank you.
