When trying to analyse STR I try to use as many data sources as possible, AirDNA, Rabbu, Pricelabs and good old networking, ask around see what other investors are getting for their units. 

There are several different types of income in the US tax code.Two main types are “active income” and “passive income".Active income is money you earn from working, such as wages from a W-2 job or income from running a business.Passive income is money you earn from investments like real estate, stocks, or rental income from your RE portfolio where you earn $ without actively working.Normally, you can't use passive losses (like losses from real estate investments) to offset active income like your salary from a W-2 job.That is unless you are an RE Pro.The reality is, that Real Estate Pro status is just a filing status similar to filing married or jointly.And if you are a real estate professional you CAN use passive real estate losses to offset active income from other sources.To qualify as an RE Pro you must:1.

Fake income documents are easily purchased online, and inexperienced screeners often miss red flags.

You don't have an income.

One other thing that people in their 60s can consider is - if you are planning on taking Social Security and making passive income part of what you live on, rental income may not count as income against your Social Security benefits.

Are these good sources?

The data @Devin Conley posted is pretty solid from my experience (I do not know Devin nor how he sourced the data, just going by my own investing experience).
