If you used them to purchase another rental/ use for another business endeavor...the process starts over. 

.: In CA it is a violation of CSLB business and professions code 7159(d)(5) to execute residential time and materials contracts.

I find that it's almost a one stop shop in that I can use it for my business checking and savings accounts, bookkeeping, for rent collection, I can issue virtual credit card, I can create all the financial reports I need to run my real estate business and prepare for tax filing and through their partners I can vet my tenants, develop state-specific leases and more.

I also believe that I should also invest is my business.

As far as the business card is concerned, to me personally I think having both things on one business card is acceptable .  

Quote from @Michael K Gallagher: Quote from @A Rao: I invest in land and have done entitlement/zoning and other DD work successfully for years.A broker called me this morning on a property I have on a busy interesection and has a QSR client who likes the location, but does not want to do a ground lease, only a build to suit. 

@Kenneth Joseph Perfido If you’ve moved to a new state and plan to conduct business there, you generally have two options: register your existing LLC as a foreign LLC in the new state or form a new LLC in the new state.

If millenial homeowners can't even change their home's air filters, or snake a toilet, or change the oil in their car, that's guaranteed future business for HVAC companies, plumbers, mechanics, and those places all need a place to conduct business in.The commercial mortgage pricing software I use has somewhere around 50 different asset classes in it.

Nope I do not intend to do any business of the lending variety in Vegas I only do joint ventures there. 

My real estate business runs without me.
