Lots of options as far as raising nightly rates as other STRs shut down, converting to MTR or LTR or doing an exchange to another state.

This might be an option for you.

If you are using a third-party site to conduct the background checks, sometimes they have the option to send a person, a denial letter, and due to the fair credit act it may be required to send them a notice, informing them that you checked their credit and background so that they have a receipt that it was completed.

Either would be a great option; I'd probably choose Roseville because it's more established, but the City of Elk Grove deserves a lot of credit for its impactful growth programs, so it wouldn't be a bad option. 

A quick google search of your state indicates the following regaridng timeline to give notice:30 daysFor tenants who have lived in the property for less than one year, or have a lease for less than one year60 daysFor tenants who have lived in the property for more than one year but less than two years, or have a lease for more than one year but less than two years90 daysFor tenants who have lived in the property for more than two years, or have a lease for at least two yearsI'd definitely touch base with an eviction attorney in your state to ensure you are not missing any steps and to have the attorney as a backup option in case the tenant does not vacate easily.

One option I haven't heard anyone mention (because they're still fairly new) is MiniStays.

Lesson learned: Always think of a Plan B in case renting isn’t an option anymore.

Another option is to invest in the market instead of paying down a mortgage.

Or perhaps I am not considering other options, so I am seeking help from this wonderful community.

There’d need to be a lot of rehab work/managing that would require you to put in that many hours.From a financial perspective, it seems like the highest leverage way to keep buying more properties is leveraging your W-2’s and then being work optional.
