Do I sell my rentals when 1% goes to 0.5%

[John Heffner]

I'm new to the post and have been investing in real-estate the last 5 years on my own and have 3 single family homes and one Duplex in West Sacramento CA.  When I bought them the Rent to home value was 1.0%+ but since the market has risen the rents are not keeping up to maintain the 1% rule.  Torn between keeping these properties and selling and using money to invest in Multifamiles out of state.
