Metrics to measure rental properties performance yearly

[Buyan Thyagarajan]

Hi Guys,

I am doing a financial review of my rental homes and would like to measure the performance of my homes. I do the following .

1. Get all rents for 2021 and subtract the expenses which are Principal, Taxes, Insurance  and rehab work.

2. I compute the Net income which is always very low for me for one of my rental homes like less than 100. 

I want to know what metrics do you guys use to measure the performance of your rental properties on a yearly basis? How do you decide one property is better compared to others and How do you decide it is time to sell a property? Any help on this would be helpful.
