Very difficult area to be a landlord.Tenant base is lifer tenants. very tough on the housestheft is rampant you leave a home vacant for more than a few days and you HVAC AC unit will take a walkKids break in and trash them.YAZOO Clay screws up the foundations big time.And lastly with those homes they were built so cheap in many instances they are just functionally obsolete and take way more maintenance than other areas of the country.

As there are Californians still moving here, the vast majority are instead picking the states with low or no state income tax like Texas, Florida, or Tennessee.Although we still have a positive influx of people moving here, more people have been leaving due to rising housing costs in recent years.To put it in perspective, we saw around +45k in the 2010's.Overall, CO is basically a balanced net migration in recent years which is likely to keep home prices steady....

You can also leave in place.

Some risks include:- Declining property values, leaving you with little or no equity.- Rents staying flat while property taxes and insurance increase.- Unexpected expenses that eat into profits.For example, some investors who bought in 2022 at high interest rates expected strong rent growth to cover costs.
