If the closing is delayed what happens to my furnishings or leases that may have been negotiated re written prior to closings based upon dates and amounts.

We currently have 2 properties under contract now and have a couple more we are negotiating. 

We were in the middle of negotiations when our fha decided to stop lending to anyone except Owner occupant.

It might be good negotiation practice to lowball an already low price.

When buying a property from sites such as Auction.com, Hubzu, etc. there's no negotiation allowed.

Start calling sellers today and start negotiating. 

@Joe Kim If the seller rehabbed the property, you should ask him to provide a new roof before closing, or at least negotiate more discount.

Below is my basic math for my investment: Annual Interest N (years) PV PMT/month Monthly Rental CF 4% 30 $ 180,000.00 $ (859.35) $ 1,500.00 $ 640.65 The 180k price tag is not negotiated yet.

Are discount points and interest rates or any other closing costs negotiable?

If that was you then I found you to be an excellent negotiator (which is more than half the battle in real estate imo).
