When to re-finance?

[Kamil Maras]

Hello,

At the end of 2013 I've purchased 4 duplexes free and clear.

1 of 4 with capital invested $95,000, the other 3 with $125,000 invested.

Current market value is approx $130/135K. These properties are in South West Florida.

My question is how long should I wait to refinance these properties. Which strategy would be more common: to hold for 2/3 years and collect $1,000 on each per month or to re-fi in the next 4 months and keep that money working.

Please let me know if I'm missing any info to help with the evaluation.
