Very good resource for getting set up with STR property managers, cleaning services, realtors, lenders, etc. https://www.getchalet.com/

This ensures a clean transition of ownership and responsibility for insurance purposes.

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. 

The current owner bought it for $30K and I know they had to clean up a lot of title work and started doing repairs. 

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?

Since Covid this is just the way of the world with STR/MTRs, it can require more cleaning and cause damage but if you want to complete it is a necessity. 

Dressers with a nice clean look that have deep drawers and smooth rollers are well over $1K and often close to $2K.

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

It took them several weeks to list my property on the market when there wasn't much to be done but they charge me $600+ for cleaning.

Seems a bit high on the exp ratio near 43% but we do pay a premium for our solid cleaning lady, she also stocks supplies, runs errands and other duties for no "extra" charge.
