My wife and I are looking into a SFH in Los Angeles County (incorporated) and found a house we both really like.

They current city leadership is pushing hard to expand the city west of the train tracks and almost double the incorporated city limits.  

GIS is finally starting to ramp up and specialities (including your own) appear to be incorporating the technology more into their domain.

Does anyone have or know of a great airbnb/STR/MTR acquisition and operating calculator that incorporates at least 3 debt instruments with different terms, interest rates, maturities?

In such instances, consider incorporating a clause stating that you are authorized representatives of the LLC.

Ideally I'd like to incorporate wholesale, house hack and BRRRR, short term and mid term deal analysis and any combination of those strategies.

That is a great point that I will incorporate so that the tenants do not feel that because they are "great tenants" I somehow have to subsidize their rent.

The old Zero Coupon Muni Bond, a single pay life insurance policy or annuity can be incorporated in any future payout that might be reuired.

Would we be able to pay the solar bill (whether we want to lease or pay off the bank loan to own--we don't know yet) and tell them their electricity is free, but incorporate the electricity/solar bill in the rent?

If you're within an incorporated city, the city's codes will supersede.
