When you apply for financing, the lender is going to dive into your finances and still require you be able to cover ~6 months of costs (held in a liquid asset), and may not count the rent generated from the other units. 

If they just want it gone (taxes coming due, want to liquidate for a new car or boat, kid needs braces, cousin Fred is in Jail again and needs bail) Those go right to exclusive clients.

The property is preaty nice and finish product is nice, big 4bed 2 baths.

Check net worth and liquidity of tenant.

Some parties may be looking to liquidate if their new, reset mortgage ramps up and cashflow isn't what it used to be. 

I’m curious about how most of you keep your liquid cash.

The way I understand it is that I will have to file a Form 1065 with the IRS and issue K-1s to my sister and I so we can both transfer that information when filing our individual taxes (I presume that information will go in our schedule E). 

That said, there are a number of no income verification products on the market that don't require 2 year's of tax returns for self employed and even allow short seasoning. 

I hired Alex Lozano of Winter Accountancy to do my taxes which included rental property schedule E; he specializes in Real Estate accountancy.  

Some contracts have liquidated damages, bonding requirements, etc.
