I’ve installed DIY split systems myself.

I've come up with these key features:- Internet (a given)- Washer/dryer- Pet friendly- King bed- EV charging (?)

It’s only through investment of capital for marketing, software systems, lead generation, call centers, attorney drawn contracts, title searches, etc. can someone establish a VIABLE business.  

If i decide yes, how can i lock myself down in addition to security systems, cameras, legal self defense, and anti-theft door/window stoppers?

The issue is with everything on one meter, it also means all of the systems are shared. 

If you do go with an LLC, make sure an attorney provides it specific to you (not downloaded from the internet), that teh attorney will defend it in court, that you jave an operatiing agreement and that you follow said operating agreement. 

I can put you on our referral system where the referrer gets paid whenever we close a deal with the referee.Thank you!

I would rather pay a little more now to build a foundational system for growth. 

You probably don't know about septic systems, foundations, how to look for termite damage, how to know if you need a new roof, how much life is left in the AC, or what it costs (from a contractor) to fix much of anything.  

Of the CRM's I tested that were part of an all in one system, they lacked basic task management.
