I have helped quite a few investors dispose of their 2-4 units this year and they have been cleaning house.  

Assuming this is a clean file, with no exceptions required, most Underwriters take anywhere from 48-72 hours to review a loan and get CTC, or provide further conditions. 

Generally speaking if the people are clean the pets are also.

I updated the electrical, painted everything, and “cleaned the property up nicely” exterior and interior.

Have contracts or covenants that keep newer homes there and keeping yards clean.  

Good afternoon, I currently live in the UK in a property owned here with my partner, I have two properties in WA- One is a long term rental property with no mortgage that I inherited in 2020 and the other is currently used as an AirBnb with a mortgage that I am still paying and have been for the past 4 years.I am looking to sell the house that has no mortgage however we have to wait untill June for the tenants to move out and it is unlikely that it will sell before then as it needs some work done to clean it up for listing.What are my options currently?

With the exception of 1 bedroom units, you basically have 2 options:-Oversized/commercial machines (potentially multiple sets)-Off site cleaning with clean spares on siteThe latter is almost always the most efficient and basically what hotels do at scale.

This was a clean foreclosure property, which is usually difficult to find.

I know they are crazy guest friendly but this seems over the top.Guest didn't deny it....responded with "I payed the cleaning fee, why would I clean up?"

It would be wise to rectify it before transfer of title so your starting off clean and hopefully won't have any issues when you go to sell down the road.
