I live in Minnesota but have a video editing business online so I can go anywhere and there wouldn't be positives or negatives to any. 

Checked info online and should be getting some sort of updates, but nada.

You should be able to search (if your county has online records) for your tenant’s name and/or all previous addresses listed on the tenant’s credit report.

I acknowledged his concerns but was unable to resolve the issue.Since the tenant moved in, I have experienced escalating issues with his behavior, including:Lease Violations:Moving items without permission (furniture, safe, carpet cleaner, TV from his room to another tenant's room).Accumulating boxes in the garage, potentially exceeding the agreed-upon storage space.Installing a security camera in the common living area, which is a direct violation of the lease agreement.Failure to submit a work order for alleged issues with the smart lock, as required by the lease agreement.Behavioral Issues:Aggressive and confrontational communication.Unfounded accusations and personal attacks.Refusal to communicate through agreed-upon channels.Loud and disruptive late-night behavior (banging on the door, kicking the door) due to alleged difficulties with the smart lock, often accompanied by profanity.Harassment of my son, the designated on-site property manager, by making disparaging remarks about me and refusing to cooperate with him.Potential for Neighborhood Disruption: The tenant's late-night outbursts have the potential to disturb neighbors, although no formal complaints have been received.Unreasonable Demands: The tenant unreasonably demands advance notice of my access to the property for storage purposes, despite the prior agreement and my right to access common areas and my own storage spaces.Safety Concerns:While the tenant has not directly threatened us, his actions, including the harassment of my son, have created a concerning and unsafe environment for my son and me.Goal:My ultimate goal at this point is to evict the tenant due to his ongoing lease violations, concerning behavior, the harassment of my son, and the potential for neighborhood disruption.Questions:1. 

is there a way for me to create an online STR guestbook for free? 

BiggerPockets is an awesome online community for anyone interested in real estate investing.

Look at other rentals in the area and see not only how they are advertising or promoting online but also the inside and outside of the rental so you can create a similar environment to try to replicate the same results.

You can find them through local real estate investment groups or online platforms.Auction or Estate Sale: If the property has unique characteristics, especially being a large, old Victorian, it might attract specific buyers looking for such properties.

Then I'll focus on paying off mortgages and making my investments "safe" instead of focusing on growth.

You can also check their reviews online at Google, Facebook, or Yelp.
