First off, hi everybody. I'm Ali the broker, the founder (and moderator) of AskNYC_Coops.

I started the subreddit because I had questions that didn't seem to fit anywhere else on reddit. I try to make it nice here, and I certainly think you all do a great job of that.

But lately, people have been asking me about posting listings (and in one case, posting a listing).

Is that something you want in this subreddit? Whenever it comes up, or maybe just once a week on "Listing Tuesdays"? Or never?

Curious to hear from the community, please.

Update: Thanks everybody for taking the time to cast your votes, extra thanks for the people who added kind words, and r/AskNYC_Coops has now added a new rule:
"No Sales or Rental Listings."

There are a small minority of people who were like, "listings are okay if we can roast them" but as a small-shop broker who has to get along with the Big Guys (who have 80% market share) it really opens me up to having to apologize for someone else's joke. So let's not even open that door right now.

Forgive my ignorance, but I'm trying to dig into the math of a mortgage prepayment, so I can calculate the division between principal and interest going forward.

Let's say I have a hypothetical $100K 30-year fixed at 6%, on which I've made three payments (so when I look at the amortization table, I see that my principal balance is now $99.7K).

And then for the next payment (Payment #4) I decide to put an additional $10K towards principal. So by my math, my principal balance should be $89.6K (the $100 towards principal from Payment #4, plus the extra $10,000).

How do I understand the next payment that after? It wouldn't be Payment #5, right? Do I just jump down the amortization table to find the balance of $89.6K and work from there, so I'd have accelerated all the way to Payment #84?
