Where to go from here? Brooklyn property with low cashflow

[Koray Kilic]

I have a single family property in Brooklyn with a MIL suite that I originally bought to live in in 2018. right now its rented out.

• MIL unit is 1 bedroom apartment = $1500/m
• Main unit is 3 bedroom apartment = $3200/m
• detached garage =100/m
• Total cashflow 4800/m 
• Mortgage + expenses  = 4500/m
  
• Cashflow 300/m

I originally purchased this property for 870k with 20% down (roughly 174k) Right now its roughly worth 1 mil and I have 690k mortgage. It has appreciated roughly 130k since I purchased it, so roughly 3600/m in 3 years of appreciation (or 5% per year). So my question is should I sell this property and look for better cash flow or keep it and be patient? right now I would be able to sell it without any taxes since I lived in it the last 2 out of the 5 years. Thanks in advance!
