Both the driveway and back patio are concrete pads that are cracked and broken (beyond repair).

@Felix L PerezIt is okay if you are not proficient in tax - you can easily hire a tax accountant to help you.I am not good at plumbing and I would never dare to try to fix my plumbing issues.If you are involved in a flip that you acquired the property in 2018 - there won't be any benefit that you can use to do on your 2017 return.Expenses that are ordinary and necessary are deductible.

@Chris MacDonald Your trip must be primarily for business (ordinary and necessary -- necessary meaning more like "appropriate" than "absolutely have to") to get some deductions.

I have done flooring, tile patios, hot water heaters, masonry work, molding and concrete work on personal projects so I know some about cost of repairs and timelines of projects (Always over on both from my experience).

to take a business deduction - the deduction must be ordinary and necessary to your business.

It's supposed to be considered ordinary income, but when I plug it in, my tax bill rises by 50% of the amount of interest I report. 

If an audit ever comes up - I would just mention that the LLC is required to make the payment otherwise the property would go into foreclosure; hence is it ordinary and necessary for the partnership to make those expenses(and therefore qualified to deduct the expenses).

It's not like being in a patio home development where every house is the same so it truly comes down to the opinion of the appraiser plus the opinion of the buyer.
