New to industry-Quick question
Hello all,
I am looking to buy my first investment property and I see on the MLS that it says, "membership amount $70,000" and that the seller will assist with $20,000 towards the "mandatory country club buy in." What exactly does that mean? Does that money have to be put up front along with the purchase price? I've been seeing that on a lot of properties. I'm curious as I am new to being a Realtor and future investor.
