I will start another post like I did with the STR valuation research.

@Luis Cerwin as others have stated, Nov - Jan is the worst time of year to have a vacancy.Majority of tenants live paycheck-to-paycheck, so all their income goes to Holiday spending starting with Halloween, then Thanksgiving, then xmas, then NYE.January is also historically the worst month for rent payments due to Holiday Hangover Spending.

I'll never forget what he told me, If you ever want to start purchasing real estate simply call this guy and write him a check and don't ask any questions.

How exciting to be just starting out in the space, congrats!
