Now assume you have 1 repair(clogged toillet, leaky faucet, burner not working, etc) per year.

yes, we pay as soon as we get the invoice....hard to know if we are getting scammed on pricing though...for example just had 2 bath sink faucets installed with under counter shut off valves, and replaced a defective smoke detector...charge was $433,  of which $48 was parts  (not including the faucets....)

The last one took me 3 hours to change a faucet fixture in my bathroom. 

I had the opprtunity to look into the last inspection report, dated January 2024 (done for the other buyer who backed off)  indicates minor issues incluing lead water Line (from Meter to the faucets).

For example: no hot water but it's a brand new water heater, faucet leaking and brand new faucet, kitchen sink leaking and it's a new sink and pipes underneath. 

I became very proficient in installing ceiling fans and light fixtures as well as doing minor improvements such as updating the bathroom vanity and changing out the counter and sink faucet.

While looking around, you might notice other things, like a dripping faucet, or even damage caused by the tenant, like holes punched in the wall, or broken appliances.

Timely fixes, like repairing leaky faucets, replacing air filters, and addressing small appliance malfunctions, maintain the property and create a positive living environment.

If it has been running for more than a week and you know there are no leaking toilets or running faucets.

It's worth paying for a cleaner that shows up when you ask, doesn't have to come back, and communicates any findings during their clean (leaking faucet, running toilet, etc.) you could always find someone who has a small business and are starting out, onboard them and grow with them.
