Is it better to diversify your portfolio in one geography, tenant base, style of property (SFH, Multifamily, Apartment).

Some rents in what some define as an A may hold strong values but rents compared to purchase price may not be comparable to a B.

One of the biggest factors in successful flips is building a strong team: contractors, agents, lenders, and property managers. 

I am strongly considering investing into private notes with Aloha Capital.

If you’re open to exploring outside the Bay Area, markets like Milwaukee, Chicago, and parts of Indiana offer strong potential for flips and rentals.

It's going to offer Strong economic growth, Appreciation (especially in DFW), Tax advantages (no state income tax), and a Growing population, including infrastructure and amenities. 

A while back you ripped on my style of slow and steady long term investing in buy and hold real estate with low down payment conventional loans because it's not as fast as your style and the potential of cash on cash returns isn't as high.

That can make it easier to communicate the opportunity effectivelyTo expand efficiently, consider targeting local real estate meetups or investment groups San Diego has a strong investor community.

Miami has strong demand for short-term rentals, but make sure to check HOA rules and city regulations since some areas have restrictions.

I'm not sure why not - one of the great parts about real estate investing is that you can build a team around you for aspects you aren't as strong at or simply want to delegate to someone/expert and do the others yourself - look up "Core 4" for example - where you can have an agent, lender, manager, contractor all at once for your investments and can theoretically just let them do all the interactive work
