Using Airbnb can 2-3x the income of a rental property, if it is in populated & traveled area. 

Once you have this team in place, you should be able to confidently invest in any market.As for picking a specific market - I would go after one with an increasing job and population growth.

My recommendation is to choose cities in safe and economically diversified areas with above-average income and population growth.

In 2019 California’s population was estimated at 39,512,223.

Generally there are still 70% LTV loans for properties with investment grade credit tenants and 10 years or more remaining on primary term lease with population of at least 50k in a 5 mile radius and average income of 50k to 60k plus.

We are in a situation where it's too expensive for the local population to own as a primary residence but yet not Lakeshore for those who can afford it as a secondary home which many wanted when we listed it back in 2017.

If there are no new jobs, it must still be a population influx and someone has to pay it.Section-8 (The American Taxpayer) has deep enough pockets to absorb rent increases.Maybe a lot of Section-8 people have either moved there from elsewhere (such as gunshot Chicago, which has to be scary living there), or a lot of Cradle to Grave welfare recipients are turning 18, or the Prisons are being emptied early due to some kind of political push.Increase in demand causes higher rents. 10 applicants for every unit, vs 1 applicant every 6 months--where would you feel more comfortable about raising your rents.

Our area is a small population area, but we draw from around the entire US and even the world.

@Dave Jensen I have used crime rate, population growth, income growth, median house price growth ( all from 2000-2019) to narrow down the city's that I want to invest in.

Houston will give you cash flow, and a very large tenant population.
