I’d be very careful about who you replace this tenant with. 

Your PM replaced the water heater because it was leaking.

For example:-A tenant complained about the AC not cooling, so I replaced the entire unit with brand-new equipment.

I did minor improvements to both of those, but unfortunately had to replace the roof on each (Flat roofs suck, lesson learned).

Things wear out over time, require updating, upgrading, replacement etc..

If that's the case look into finding a handyman, and make sure to shop around for the best price.Stuff I have ran into:lost keys/lockpicking [hired]broken washer [fixed myself]shower door [fixed myself]AC clogged [hired]Microwave broken [replaced myself]holes in the wall [fixed myself]

Then interview them.Now, let's look at your issues:1) How did replacing a toilet result in a burst pipe and flood?

Disallowed losses under wash sale rules increase the cost basis of replacement securities, potentially reducing future taxable gains.This post does not create a CPA-Client relationship.

For a rule of thumb, replacing a commercial boiler can range anywhere from $20k to $150k, depending on the size, age, and efficiency.

But it gives you a chance to get a fresh start....make your place nicer, replace appliances, new paint, get rid of carpet and replace with LVP, Etc....
