Over the past few weeks I have put together an excel spreadsheet containing data relevant to todays unpredictable market.

I also find city-data forum to be helpful.

Did some of my own math and research about the vacant land and wrote an offer requiring the seller to cover the cost of a perc test as well as a survey.

I would be ready to have supporting data as to the necessity of them and be sure to include exterior cameras as well, not only in the common drive/entry area, but along the rear permeameter as well- otherwise it seems as if spying on the interior might be miscommunicated as the goal, and if truly for security, you would be covering all points of entry without exterior cameras along all exterior walls. 

You will have to hire someone to come to perk tests for your soil.

The classes are very straightforward and I didn't think the school or state tests were difficult, although A LOT of people have to take them more than once before passing. 

fwiw, I am quite proficient in Excel (have some experience with data analytics, pivot tables, formulas, macros, etc.) so I could likely easily manage a small database of leads by myself just with Excel…and create my own dashboards etc. but anyone using something in particular that they enjoy?

I’m new as well with some exoerience in residential valuations and property data and I’m in LA!

For 3-4 units FHA requires the property to pass its self sufficiency test.

HUD publishes data monthly that tells you how many 203K loans get closed and which lenders do them.
