From there, it's easy enough to look up the tax rate for corporations and make your tax burden assumption.

However, I’d like to have a space of my own before living with others again (I plan to house hack again with my next property).I’m seeking advice on how to move forward, as I need to consider things like utilities, taxes, landlord/umbrella insurance, and managing the property, especially with someone renting my garage.Specifically, I’m curious about renting out individual rooms and living on my own for a little while.

There are rentals, fix and flippers, lenders, tax liens, note investors, STR, commercial etc.

It is my understanding that the new owner will have the house at the cost basis of my purchase price, for calculating capital gains taxes or depreciation.For gift tax purposes for you - FMV.For capital gain tax purposes for the recipient - your original basis/purchase price 

Though I am unsure how I would amortize the up front remodeling costs for P&L, tax accounting.2) Interest only loans term loans -  Would allow current owner to have cash flow on the property, without eroding the asset value. 

Malibu allows it but requires a 15% "hotel tax" on the gross revenue.I would recommend looking out of state or underwrite the property as a long term rental in the event laws change.

Lots of depreciation you will pay no tax maybe even shield some W2 income.B.  8k maybe 10k if you pick the right guy to lend your money to in interest income you will be paying much higher tax rate on this income FYI no depreciation expense. 

As U.S. citizens residing in Europe, we are required by the local tax code to hold the property in our personal name.

Do you know if that could work the same with something purchased at a tax auction?

There's obviously quite a bit of diligence that comes after such as who the key principles are and their credentials/track record (both balance sheet and experience), the underlying real estate and thesis behind the investment & tax prep and audit procedures but as a general rule of thumb if the investor can't get past the first part which is understanding what they are investing in, passive investing is probably not for that individual.
