I am looking at building a new four or six plex  complex in the Phoenix area on raw land.  

It's a risk raw land owners take everywhere, we've owned land in several spots in CA and never had a problem.

It is raw, unfinished.

Would love someone with experience to post a few bullets and basic costs of typical order of buying raw land.

Realtor associations, MLS association, CoreLogic (backbone for most MLS and title systems) - between those sources of both raw data and their reporting/research you should have plenty to sort through.Let me know if I missed the mark on this answer!!

I have bought property in SC for a few thousand and then sold it in on Ebay with a Quit Claim deed and doubled my investment.I recently sold a lot to someone in my local real estate club who understood tax deeds.Maybe the land would be wanted by an adjacent property owner.I sold a lot to someone that just wanted to put a mailbox on it so their kids could go to that school distict.The land just needs to have value to someone else to make it a good investment.In general raw land is harder to sell than a property with a house on it.Also watch out for unbuildable properties due to things like flood zones or flood ways.I would factor in 4k to quiet title whether you need to or not to limit your risk.

If this is your first purchase or if you're just starting out, commercial lenders will typically look at the raw numbers.

We have a portfolio of mostly raw land that I’m developing into buildable lots.

I never go above that formula for flips or ground up development and raw land development.

I feel like I have to piece my analysis together with google searches one by one, and as an amateur in analyzing the multifamily market, I haven't identified the sources that publish some of these forecasts (however bad you think they might have been) or the ways to get basic raw data - like cap rates and information on typical debt financing structures.Also - I should have stated this in the original post - but yes, absolutely, I believe that this "crash" (if this happens) will have drastically different outcomes at the regional level.
