My plan is to take the money from the sale of my Oakland house and reinvest it into multiple properties to start off my investing career--I'm just not sure where and if I should go SFH or multifamily. 

I'm open to flips, buy & hold, Foreclosure/REO/Short sale pretty much anything outside of section 8 if the numbers are right. 

Also post Facebook marketplace, craigslist, Facebook yard sale, community websites, Nextdoor Write up a canned reply to zillow / email leads and save it on your phone and computer.

Initial CapEx Funding at property closing: At closing, as part of my 'cash needed to close' calculation, I take 3% of the sales price and set it aside in a separate CapEx savings account.  

The best is during a moving sale.

If I read between the lines on this it seems like you have a fourplex for sale where the "potential rents" are $2,400.

I'm in sales so they tend to tone it down to me personally but they absolutely at times blast my company and "threaten" to create a competitor.

Of course, we can also assume that over 30 years, we will face 0 inflation or even deflation, but then REI as a whole would become very challenging.Final point, I do not include "appreciation over inflation" in my calculation: the only reason why the sale of the property in the second example is higher than the purchase price is due to compounding inflation.

I've completed my Sales Agent courses and am set to test for my Texas License in the next 30-45 days.

If your potential sale price of $850k is correct, I would sell.
