Seriously listen to @Michaela G.Everything that I've been taught about credit history is spot on to what she's saying.If you go and pay off the amount it will become recent history and carry more weight than just leaving it alone.If you're going to do anything, speak with a reputable credit repair person.

.), instead I decided to start building my own lead category verticals, comprising of Probate, Pre-foreclosures, Evictions, Violations and so forth; get them skip traced and call owners, instead of mailing them. 

Many who fall into this category seem to take a long time to close on a deal because of cold feet, fear of making the wrong decision, and always thinking they can get a better deal. 

Also, their "accounting" portion is only for very very light expense tracking (and only if it fits their model - i.e. you cannot add any expense/revenue categories/accounts).  

I actually have a copy of the lease but it is not signed... do you think this holds any weight?

@Hiro Kitagawa, qualified improvement property has become a bit more interesting than your CPA made it out to be.Now, there is in fact a category for owners of non-residential real property called qualified improvement property (QIP) that as of 1/1/18 replaced the old qualified improvement property (yes, same), qualified leasehold improvement, qualified retail improvement, and qualified restaurant property classification rules, as well as includes some property that would not have fallen into those buckets previously.The committee reports indicated that QIP placed in service on or after 1/1/18 would be eligible for a 15-year depreciable life as well as bonus depreciation rather than the standard 39-year, non-bonus eligible method applied to non-residential real property.However, the law was not drafted correctly, i.e., there was a technical error, and the section of the tax code describing 15-year property (Section 168(e)(3)(E)) was in fact not amended to include qualified improvement property.So for now, strictly-speaking, in 2018, qualified improvement property is regular old 39-year property that is not eligible for bonus depreciation.We do expect that a technical correction to the law will be made, but for now the IRS has actually stated that it cannot guarantee that absent legislative correction it will accept the legislatively intended change in recovery period and bonus eligibility.Anyway, this is neither here nor there since you have stated you are a landlord of residential rental property rather than non-residential real estate.And this does not affect the application of 100% bonus depreciation to both qualifying new and used property place in service after 9/27/17 and before 1/1/23 that @Yonah Weiss pointed out.

While I know as dad's it is our prerogative to fix things for our kids and make everything easier, I think that she should feel the weight of $100K of debt as much as possible.
