Make sure you’ve incorporated repairs, capex, vacancies, etc. into your cash flow numbers.

. - Depending on what you're wanting to do with the home, there are several traditional options that you can explore to incorporate your upgrades into your mortgage.

Your post is not clear on if you are in the city of San Diego, some other city in San Diego county, or incorporated area.I am assuming zoning already allows someone to legally live in RVs on the property. 

But if you can find a way to incorporate common financial sense, you’ll not only thank yourself later but even be able to afford to buy yourself an expensive treat!

The trust and the LLC are the owner of the asset/real estate, so even in the scenario that they guess, they guess wrong.As you grow, or you include more partners, you should be incorporating more pillars to support the business that you are taking part in.

I see lot of Business incorporating in Delaware or Nevada.

Truthfully I would like to go straight into a triplex or higher, but a duplex seems realistic for me at the moment.As for the property taxes, I could be wrong, but ideally I think those should be incorporated into your analysis of the property when you are looking to buy.

Also, they should provide comparable assessments as one would compare sales in a grid format and provide a narrative explaining the variance. 

I also suggest that if you can, get a copy or a narrative appraisal and following the outline will help you in your determinations.

Everyone I have listened to or that I have worked with have differents strategies, so I just try to incorporate them all into my techniques and become better!
