There have been several high-cost damage issues and one where they are at fault and confessed to, resulting in thousands of dollars, that have put me in the hole to the point I won't make anything off of this year's lease.We live in Colorado and it's made it difficult to manage, even with paid professional services, so we are selling as soon as they can vacate.

Whatever the City won't adjust off you get to deduct from your taxes anyway, so you're not actually paying the cost of the water usage.5.

I know my credit went down because I had two lines of credit that I paid off entirely, and decided to close before going abroad in 2021.

Rather than writing the loan off, having 20,000+ less to lend and have it take 3 years to put it back yourself via ROTH contribution limits (7k/year), can someone else pay the loan back for the borrower?  

Here in Texas law treats golf carts similarly to motor vehicles, so there are regulations to be aware of.

There are many more but that is just off the top of my head.

Don't limit yourself to targeting 8 units, as @Robert Rixer said focus on the numbers of the deal, and make sure you are comfortable with the risk/reward trade off. 

I have another car that’s paid off that I am going to sell for around 15k.

On the surface it also sounds like you have a lot of local support for managing and maintaining the property but I suspect that will kill off most of the returns.The real information is somewhat hard to come by as the developer controls much of the market, the rental management, and a lot of the previous pricing data as they didn't report to MLS for much of their history.  

Ease off the gas pedal local governments, holy sh!
