I coordinate lots of deals in this area. 

Partly for the strong casflow that we enjoy after 30+ years investing along with other reasons.I would probably not buy additional property all cash, but improvements and betterments will be paid in cash or at least quickly.Leverage is a great tool when used properly. 

Were they properly screened?

Unless you find a properly zoned property, it is no go.Just start looking in places that STRs are allowed rather than try and swim upstream.

Do you have the knowledge and insight to handle any LT complaints and are you set up properly with your bank and security accounts and can easily collect the rent, etc?

I want to make sure that the process and documents are all proper and we don’t miss anything. 

When we acquired this properly in 2015, we used to pay handyman 20-25 per hour.

Without proper guidance, it’s easy to make costly mistakes that can derail your progress early on.Having access to solid resources—whether it’s books, courses, mentors, or investing toolkits—can help you navigate the unknowns.

Andrew thanks , will contact at the proper time

I think it is best with a solo(k) to take it to the next level and work with a professional such as a CPA or your advisor, to ensure that all your transactions are proper and are not considered prohibited.
