Flipping isn't too worrisome for me because I know in times like these I just need to make sure my quality is there and that my pricing is a little more aggressive to keep the project moving.

Would this be advantageous at all when compared to a traditional BRRRR and keep it as an investment property?

Working with a knowledgeable local agent and keeping your finances ready will help you seize good opportunities.

I'd expect cash buyers to be lower, not higher in most scenarios but I see what you mean.

I see Detroit as a possibility to keep investing.

Sell the empty lot OR JV with another investor who can take over the project and keep you as a silent partner or limited partner. 

Will also motivate him to want to keep working with you.

I personally wouldn't do that although I'm aware I would "cash flow" more on paper if I bought an apartment complex or multiple SFH/duplexes OOS vs keeping my Bay Area SFH rental.

If you mean that, you have 4 months to find financing or you lose your money.

I will be keeping in touch with all real estate investors to gain all perspectives.
