There are a few items that will come into play. 

She does all the bookings, conversations, acts as a concierge, will repair and purchase items (billed to me) marketing for the property, manages cleaning crews, etc.

Hello,I own a duplex and I just recently had a tenant move out and now it's time to consolidate the security deposit and I had a few questions and suggestions on what items can and cannot be deducted in Minnesota. 

So does the pay roll.If you do the math, and you bother to allocate proper $ amounts to all of the line-items, you should realize that $500 is just not enough to cover all of the bases.

If an owner of an income producing piece of real estate agrees to do seller financing, will a bank do a refi on it (after the 6 months or a year) even though it is owner financed and not some kind of traditional financing?

The tax law changed the deductibility of personal interest as reported on Schedule A, Itemized Deductions, hope this helps. 

I feel like Property Management is probably the one thing that is difficult to incorporate in NJ since if you account for all the items I just listed rarely any property would make sense to purchase off the MLS at least. 

As far as my tax bracket, I will probably gross around $80,000-$85,000 this year, but I do have a company 401k(traditional) with match that I contribute to, only 5% for the match and then an extra $5,000 flat for dependent care and another $1,000 towards an HSA.

I'm fortunate to have low expenses and a high-paying "real" job, so I was able to fund my own deals, all my mortgages are traditional.  

Wish I had a better response for you but you might want to reach out the file manager who is handling your permit and ask what's the reason for some of these items, sometimes the counter clerks have a check list and end up sending the applicant ( you) that list without considering what you actually need.
