I want to build a multi-billion $ enterprise through real estate and then shift into tech, (possibly real estate in space if the tech is there in a couple decades) so everything I read I think about in terms of systems and growth and sustainability.

Servicing is a costly enterprise now-a-days and I think the minimal UPB to actually make it make sense is probably at or slightly above the $1B mark.  

Also, are you using ARGUS DCF or Enterprise? 

This program would not work for wholly passive enterprises such as rentals and lending.

I rehabbed the operations and sold them late in 2012.It was then that I decided that I could either invest my cash in one of many markets, start a new enterprise or take control of my investments by actively managing them myself.

Then, when you establish the LLC, you  elect what type of entity the new enterprise will be , C Corp, S Corp, partnership, sole proprietorship.

I see you've received answers in this thread about looking for indications like enterprises like Starbucks moving in , or the neighborhood getting younger....  

Hey Peter, I live and invest in Enterprise.

But I’m wondering if it will get challenged in court, or it may have enough holes in it that enterprising LL’s will find work arounds ;)Vacancy control is a different animal, because that needs to change on a state level (basically dismantling costa-Hawkins) and fortunately both prop 10 in 2018 and prop 21 in 2020 which offered that got their butts kicked by the general CA population :) But yeah, if it were up to S.F. alone, vacancy control would pass here in a heartbeat.Probably as a reaction to the trump presidency, S.F. board of stupidvisors has never been more left leaning, and I think the city’s population has shifted more left too.

Free enterprise was essentially abolished.
