We still haven't heard back from @Rav Ram , so all we can do is speculate.  

I plan on making a move to Southern California in a few years, however, I am looking to invest with developers building high-end spec homes beforehand.I have been fascinated seeing beautiful speculative-built homes across the LA and OC areas and I plan on getting involved by the end of 2024.My plan is to invest passively in such developments while observing until I can develop such properties myself.Any advice, input, recommendations, or referrals would be much appreciated.I look forward to your responses.

As other people on here have said, that's speculation and more risky.  

If you are truly speculating then you may open yourself up to some criticism, and liability.

And, my speculation, is you will recoup all that over time and more. 

Currently many of the coins are very speculative so you may experience bigger swings than expected.

Durham is speculated to have an additional 70,000 home buyers over the next decade.

We don’t want to speculate on the purpose of the ‘retail activities’ that we have observed but we think the best solution would be for you to move out and accordingly we will release you from your lease agreement and waive the notification requirement and the early termination fee.Additionally, if you leave your apartment in good condition, broom clean and completely empty, and move out before March 10, we will return your $______ security deposit (less any outstanding water bills) on your move-out date rather than making you wait the 30 days permitted by Ohio law.

If you are new to RE, I'd suggest you stay away from vacant land as that is more speculation than investing, unless you have a buyer in the wing.

This article is definitely an eye opener for all newbies like myself and anybody who intends to speculate with flipping strategies.
