Also confirm that county maintenance liens are added to the tax debt.Fourth, you can contact your county ordinance department, usually those who handle house condemnations and mowing liens, and provide them with the property tax number, photos of the violation with a complaint from the named neighbor about the risk. 

I could only imagine the legal agremeents needed on who has what right/easements etc.

. - PRO TIP: many builders lose their license then create new company in name of wife or other relative/friend.2) Check Better Business Bureau, but don't assume all the complaints are legit. - If there area MANY, then that is a problem.

Are both parties represented by legal counsel?

As for the window blind, I told the PM that if the tenant complaints multiple times, I would just replace it eventually.

But I can't seem to find any information about what are legal requirements for owners and property managers.

Real estate agents can’t offer legal advice, and at least in Ohio, they can’t alter the boilerplate form.

Knowing this information will help you identify the right professionals to bring on board.At minimum, your team team should include:Financial Advisor: to help with investment strategies - portfolio diversification and risk management.Real Estate Agent/Broker: to help with property acquisition and market analysis.Accountant or Tax Advisor: to help manage financial records, tax planning, and optimization.Attorney: to provide legal counsel for contracts, agreements, and investment structures.Mentor or Coach: to offer guidance, insights, and industry knowledge.Networking and Relationship Builder (for everything else you will need): to connect you with potential partners and collaborators.

I'm also curious what your experience has been with neighbors - have you gotten a lot of complaints, pushback, etc? 

Consult an attorney and tax advisor to structure the arrangement legally and effectively.This post does not create a CPA-Client relationship.
