This has driven up the property taxes there. 

It is your first year when you get the major tax savings windfall due to cost segregation and bonus depreciation.

STR seems to have better tax benefits (in the right market) but is it worth it at a distance ???

From a tax standpoint, there are additional disclosures to make when selling a business asset for less than fair market value to a related third party. 

Quote from @Fred Scott: Sunrise Capital Investors - Mobile Home Park Investment FundI've seen a few posts about them here but none of them actually talks about what the actual annual returns have been.They are advertising heavily for passive tax deductions which is fine but what are the actual returns over a period of (say) five or ten years?

However, there is no specific holding period contained in the tax code or regulations and there is no "safe harbor." 

So if you have the property for a total of 10 years, moved in at year 8, little value or tax advantage.

After collecting tenant pass-throughs for the year, do you pay the property taxes at the end of the year or the beginning of the next year?

I do intend to stay close to home - but home provides only annual opportunities and I’m looking for year round possibilities with tax deed properties. 

Keeping clean records from day one really helps when tax season rolls around.
