Not all multifamilies/apartments are worth keeping

I know a lot of people are taught that after they flip residential houses, they then need to go to commercial properties.  By commercial, most of these programs mean apartment buildings or more than 5 unit buildings.  I just wanted to share that many (and I mean) many of these "apartment" buildings are not worth keeping in your portfolio unless you are fine being a slum lord.  If you at the bottom of the market rent, you can expect to have the bottom of the market renter.  This means no care for your unit, late or no payments and consistent repairs and maintenance needed on these type of projects.  Don't fall for this trip and truly find out what you are getting into before you get into these "commercial" properties.
