Analyzing investment duplex deal in Los Angeles

[Kareena Sharma]

I am trying to analyze a duplex deal in LA, asking price is $860k, rent expected about $5,500, this was bought back in 2015-16 for $460k, doesn't look like a right time to buy with prices soaring all over in Southern CA, however, the duplex does end up with positive cash flow of at least $1,000

Rent income $5,500

Mortgage+property tax+insurance: $4250

Repairs :$250

Cash flow: $1,000

Would you buy in this market or wait for the dip to come? I am conflicted with ideas such as this may not be best time to buy, or I can never time the market anyways so if cash flow is positive, why not go for it?
