I’m brand new to game and don’t want to start with practicing bad habits.

(A) A landlord who is a party to a rental agreement shall do all of the following:(1) Comply with the requirements of all applicable building, housing, health, and safety codes that materially affect health and safety;(2) Make all repairs and do whatever is reasonably necessary to put and keep the premises in a fit and habitable condition;(3) Keep all common areas of the premises in a safe and sanitary condition;(4) Maintain in good and safe working order and condition all electrical, plumbing, sanitary, heating, ventilating, and air conditioning fixtures and appliances, and elevators, supplied or required to be supplied by the landlord;(5) When the landlord is a party to any rental agreements that cover four or more dwelling units in the same structure, provide and maintain appropriate receptacles for the removal of ashes, garbage, rubbish, and other waste incidental to the occupancy of a dwelling unit, and arrange for their removal;(6) Supply running water, reasonable amounts of hot water, and reasonable heat at all times, except where the building that includes the dwelling unit is not required by law to be equipped for that purpose, or the dwelling unit is so constructed that heat or hot water is generated by an installation within the exclusive control of the tenant and supplied by a direct public utility connection;(7) Not abuse the right of access conferred by division (B) of section 5321.05 of the Revised Code;(8) Except in the case of emergency or if it is impracticable to do so, give the tenant reasonable notice of the landlord's intent to enter and enter only at reasonable times.

Vikram,That doesn't cover the case where I did not do business with the guy (you already know that), but his wrongdoing did cause harm to others.

This is not a way to protect yourself, you'll end up doing more harm than standing up on your own merit and confronting anyone who seeks an action against you.....if you conduct your business in an honest, above board, ethical manner, that's the widest moat you can possible build for yourself.

For most folks I have recommended against this strategy as the risks and spending habits typically outweigh the marginal benefits.

So when renting get into the habit of spraying the home monthly for bugs or inspecting monthly to make sure the home is being taken care of 100%.2.

Preservation improvements includes rapairs to make a property habitable and routine maintenance such as lawn care.

We don’t know any PMCs to recommend in the area mentioned, but since selecting the wrong PMC is usually more harmful than selecting a bad tenant, you might want to read our series about “How to Screen a PMC Better than a Tenant”:https://www.biggerpockets.com/member-blogs/3094/91877-how-to-screen-a-pmc-better-than-a-tenant-part-1-services-and-processesWe recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

This can apply on a macro or micro level.For example: Why not look at really old or ugly buildings... that you can spruce up and make habitable?
