Equity build up and Refinancing timeline

[Noah Hoffman]

Hello,

I am new to BP and wanted to see if anyone had any thoughts on a question I had. 

My question is about buying a multi family property 4 units with a low down payment FHA loan.

If I only put in 3-4 % down how long would it take for me to refinance that property? 

Do I need to have more than 20 percent equity to do that? 

What might the soonest I would be able to refinance or somehow use the property as collateral to borrow in order to put a down payment on another property?

Thanks,

Noah
