Paid Cash on Rental Prop and want to refinance

[Account Closed]

We paid cash on a duplex and are putting some money back into the property to restore the garage etc.   I did not realize it would be tough to refinance the property to pull cash back out to reinvest elsewhere.  We paid $30K for the duplex.  Putting in about $20K to rehab where needed and take care of differed maintenance as well as to increase rents.  Rents now for $1100 total.  It would appraise for $80K post repairs.    I did not know we could not immediately turn around and refi so that we could pull cash back out.   I am hearing that we have to wait 6 months.   Anyone have any ideas on how to refi sooner?   Clearly we will go into the next deal with a loan, but wanted to see if anyone had any better ideas of how we can get cash out sooner than the 6 months?
