I will take a NJ State pension that is slightly lower than my take home from my job pay (after all deductions have been done).

Now I am still making good money online, but I will write off most of my earnings as deductions.

Can I fully deduct all mortgage interest on Schedule E as rental expense against the subject property??

Yeah call the insurance company and pay a big deductible to fix a 200$ door and buy a used Craigslist stove .that would be bad for two reasons - a high deductible that is probably more than what it would take to remedy the situation and the fact your insurance rates will spike up .

@Christopher McGuire Some might say that your vacancy rate and cap ex allowances are too low, given the very low starting price from which to deduct your "standardized percentages" off.

I’d like to form an LLC from the beginning, so this travel and other related expenses will be deductible.

The legal use will be it's highest and best use unless you are changing it, so your comparable properties need to be similar.Consider quality, style, applicability to the area and function, deduct amounts from your comps for the negative aspects of the subject, bring the comps in line to the subject.

A clarification, if the MLS remarks addressed it as a commission split/deduct (which I doubt) they would have a case.  

You don't have to take the deduction @Christian U. but you do have to account for all allowed depreciation when the property is sold whether or not you took the deduction. 

Forgot to mention the trip is tax deductible.
