Part of what you are describing is what they call an installment land contract.

It’s 50% of the land providing 100% of the construction . welcomes first time investors Can you go into what this entails?  

Interested in STR, LTR, Fix and Flip, commercial RE, and land development. 

(Land and construction cost, expected sale price, etc.)My last development in Chicago looked like this:Land = $300kConstruction Cost $650kHolding Cost/Closing Cost/etc. $50kProfit roughly $100kThat project was in Bucktown on the nw side of Chicago.

Sacramento seems to have a lot of inventory and buildable land which will increase supply keeping rent growth slow. 

That where your agents boots on the ground expertise comes in to land you actual deals.

If so, what would make u buy a piece of land vs a house?

I believe your land is still a little too far out for the current cycle. 

Andre, Land Title, Stewart Title or Superior Title would be able to help you with that.
