You can absolutely do it in a way that leaves you as the decision maker and makes your aunt a silent partner. 

Purchase price: $92,000 Purchased this 1.5 bathroom home that is next to a large (largest in the country) indoor sports complex and a hospital.

"House hacking" AKA buying 2-4 unit and living in one unit while renting out other(s) is a great way to get a foot in door of the investing world.

I would take a functional coffee maker and plenty of coffee over almost any other amenity. 3.

If we rent for 10 years, maybe it will be a money-maker after all, someday.

Services such as pool maintenance and cleaning can be written-off your taxes in the year they're performed.That sounds incorrect - Just because something adds value to a house doesn't mean it needs to be depreciated over 27.5 years.If the item is not attached to the structure of the house, it doesn't need to be depreciated over 27.5 years.An indoor pool may be required to be depreciated over 27.5 years.however, an outdoor pool does not need to be depreciated over 27.5 years. 

I felt like you were directing your opinions towards me instead of the thread maker.

What matters is how the indoors compares to the outdoors in the amount and type of spores detected.

For a few dollars more per gallon, yes, it will absolutely destroy any odors in those walls but it will burn your eyes and is not worth it for this kind of indoor work.As @J Scott has pointed out, the worst care scenario is that the stink never really goes away.

Then I vacuum it up the next day.This is for fairly easy smells (probably not effective for indoor chain smokers or male cat gone wild).2) I like the Nature's Miracle for pet odors.
