Minimum Amount for Cash Out Refi?

[Derek Luttrell]

Hi Everyone, 

I'm in the works of buying a 2/1 SFR in suburban Indiana for $20k cash, with anticipated $10-15k in rehab, ARV of $65k.

Pretty much looking at a BRRRR method here, but my question is--is there a minimum dollar/loan amount required for the refi portion? Or, if I wanted to pull out just $20k to do an identical deal, would that be an option?

My question may be a little premature since I don't even have the property yet, but I'm playing chess with myself and trying to think ahead/map out my strategy and goals. 

Thanks for reading,
