Because 3.6k per year is good, but then a tenant moves out, the house sits empty for 2 months so u just lost your 3k (mortgage 1.5k, lets say)...Every 10-20 years you need a new roof, thats about 13-16k  (Although 8 years ago I dishwasher/washing machine/Ac/heater, those things break...I dont see how landlords can retire with $300 cash flow from 10-20-30 properties...I understand when people make 1k per month in cash flow, but $300, not sure how all this works...Exactly; nobody is getting wealthy or retiring off $300mnth cash-flow, for all the reasons you touched on. 

When prices drop, rental demand decreases, putting downward pressure on rents.The TakeawayThe critical factor for success with this strategy is location—specifically, investing in areas with significant and sustained population growth.

@Heather Bailey When house hacking with a separate rental unit, ensure proper insurance by obtaining landlord or short-term rental coverage tailored for Airbnb activities, in addition to your primary residence policy.

This means that your permanent residence is excluded (except if you are doing a house hack in which the part that is rented out is eligible for cost segregation).

Also, these deals tend to have very thin margins because the brokers will soak up a lot of the up front pricing while also pressuring you to get skinny on the rate.

Just be sure to clarify that she isn’t a leaseholder but is authorized to reside in the unit.If you’re concerned about liability or want more peace of mind, you could ask the primary applicant for additional security, such as a higher deposit, depending on what’s allowed under Colorado law.
