So about 1,100-1200 monthly expenses after groceries and other miscellaneous things I’d say.This is what I own:Bank: 35kCash: 7kInventory (business): 230kRobinhood brokerage: 27kFidelity Roth: 5.5kRoth 401k: 32kPersonal money market account: 15kBusiness money market account: 42kTotal liquid cash: $393,500Debt: -16,000 college loanHow should I go about investing this?

Remember @Costin I. that for any liquidating distribution of a partnership, such as the LLC, the distributions should be done pro rata. 

What types of programs are typically available for borrowers with 800 scores, 1m liquid, looking for 350 to 400k loan to buy land and build a spec for resale.

Depends on how liquid you are for more real estate purchases 

Well we got him as executor on the account unfortunately I have hit a liquidity issue.

One cool thing about the 203k is, although the FHA loan only allows the property to be up to 4 units, you can actually buy a 5-unit or 6-unit and convert it back down to a 4-unit, and it will still qualify.  

A really cool report by Apartment List showed VB has one of the fastest growing rent changes in the country at 3.9%. 

I’ve heard from some lenders that I need more equity, others said there was a “cooling period” required after purchase to be able to use additional gained equity in land (from rezoning), and others needed prior experience.

Those that teach, can't do".BRRRR out of state is very risky business IMO.If you have a $150,000 liquid you could pick up a nice flip in Texas.Haven't been here long but have been long enough in the RE market to see how booming things are here and the deals to be had especially from flip standpoint.I'd stay local, buy, fix and flip and only buy, fix and hold when you cash surplus allows you to do so.Just my opinion and wishing you all the best

You never want to deplete your liquidity into a deal.
