Now that I've had a bit of time to put in some info into rental hero, under the "profit and loss" section, you can save/print a PDF with details. 

Is Bigger Pockets no longer offering AIRDNA under tools as part of the pro membership?

In San Francisco proper the discrepancy between 2 and 3 units is bigger I assume because of condo conversions.

Home could've settled and nothing further to do or you could be seeing a bigger issue at hand that the seller needs to fix.

They can find things but if they require say overhead lighting and you don't have it that is a bigger issues then small fixes. 3. 

I honestly wouldn't even trust anything QB is telling you when it comes to taxes.You're in a partnership, which acts like a conduit to pass through the income/loss of the activity to the individual owners.

I can afford to have the unit empty, but obviously don't want to do that, and am at a loss around what I should do going forward.

Someone told me its very hard to sell these properties and you have to sell them at a loss if you want to get rid of them.

You can also recapture loss's in it compared to a C or S corp. so it does have tax planning benefits.
