Yes, they're on HR Block. I'm not moving them out of it until after the house is gone and done with.
Looking at their 2017 return:
Form 8829 - Business use of home
The house is being depreciated here. Full purchase price, no exclusion for land. Now, since it's the home office a tiny % of the value is actually being depreciated, but it's still double the amount that should have been depreciated.
Schedule E
The house was put into service on 4/30/2002, cost 196k. Looks like basis was $84k after 2017.
New roof 5/1/16 at $15,257, basis $14.3k .
Both are straight line, 27.5 years.
In other words, dad didn't set it up right and I'll have to figure out what to do. I may just have them hire a CPA to sort it all out. I can do the rest and feed it to them and they just figure out the house sale stuff.
I'll make a copy of the 2017 file and play with it, put in some estimated numbers and see what I come up with. But yeah, this isn't looking good.
