We're currently focusing on the San Francisco Bay Area market.If you’ve used other corporate housing services, what doesn’t work in your experience or could be improved?

It's a given that it would cost more than the same trip via a ground car, even if ground transportation doesn't gain its own improvements (which it will - autonomous networked vehicles will make the ground trip safer, faster, and cheaper than present ground transit, and that is *much* closer to a broad implementation than air taxis). 

Operator error tenet should be paying.  

Although you might think that only applies to a contractor, they have the following example:Operative (Speculative) Builder (Also known as “Flipping”) A person who owns land and builds with the intent of selling the building once it is complete is an operative (speculative) builder and is a prime contractor.

Do you really want to be operating a business.I would sell and invest the money in a income fund of some type that could probably generate a 8 - 10% return without a problem.Let your children get loans if necessary.

Pad your reserves with the cash flow.The liquid side account absorbs month to month fluctuations (extended vacancies, major repairs, etc. they WILL happen) and keeps you alive until you can find other options, or until conditions improve.

If you did that you would avoid all tax on the $566K ish gain (plus you would avoid the three years of depreciation recapture which would be close to $100K - or another $25K of tax).Hand grenade math tells me that unless there were huge capital improvements you're looking at a minimum of $100K tax bill. 

@Jon Dorsey The 'environment' does not change business fundamentals.Parks with POH are two separate business: one is the MHP, which generates revenue and expenses from the operation of the park; this has its own value and risk profile.

Being a real estate investor and business owner, operating thru S Corps, C Corps, and LLC's, I know of lawsuits filed against the LLC and the owner personally, an S Corp and the owner personally, either by piercing the corporate view, or for the owner being personally negligent.

Doubtful th enew business oriented government will make changes to improve our legislation but at least it will not get worse.
