This will impact my revenue and I've barely broken even in my first 2 years.

Example - say the tenant calls in to the PM and says the front step or handrail on the house is broken.

What law is being broken?  

We also replaced quite a few old ceiling lights with new ceiling fan/light combos and replaced any cracked or suspect outlets, etc.Kitchens got new stoves and microwaves and upgraded furniture in common areas.

So it made my tenants frustrated that when they moved in something was still broken even if I fixed them all in advance according to their inspection report.4.

So i found a house that has tall ish grass and a broken/open window with no mailbox at the location and i was to buy this property for my first house to live in for a while then eventually sell.

There is a very old door intercom and buzzer system that needs upgrading.

They installed bidets without my permission and created plumbing issues so I had to pay for a plumber to come out several times, I've had to replace a frontdoor knob and deadbolt last month even after we rekeyed the home prior to them moving in, the garbage disposal blades were jammed so had to call a handyman, repaired a broken window which my property manager claims was broken prior to them moving in even though the repair was made 3 months after they moved in.

Would need some cosmetic (paint, refinish floors, minor repairs/upgrades completed by me).

Because of their experience, I was able to get parts of the work covered under code upgrades for things that I did not build back exactly as they were before the claim (e.g. moving plumbing to expand a bathroom).At the end of the day, no one is going to care more about your property than you.
