I would suggest that discuss with your lender a home equity laon at the time of closing.
If you need a suggestion for a loan officer that is knowledgeable and helpful, contact Gerry O'Brian at CB Loans (part of the Coldwell Banker Residential Brokerage family). You can reach him at firstname.lastname@example.org or call me @ 973-723-3666 and I will put you in touch
My question is how much is the condo & how much or a percentage are you putting as a down payment? Post it here and I'll get back to you
