Insofar as negotiating a lower price, there are a few ways to make the 'bite' not as hard on the seller.
THe seller pays commission (@10-12%) to the broker on the sale price...if he takes somewhat less per ponit, he pays less commission and the 'bite' is smaller than if you negotiatie that he pay closing cos
As for maintenance, I had 2004 and 2005 points all there when I made my offer on a contract. We were in the 2005 use year, closed April 4, but I knew my sellers had paid for the maintenance lump sum in January...so I put in there: seller pays 2005 maintenance costs THey accepted. I had to keep the sales price rather high because it was BWV with a high rate of ROFR...but you have room to negotiate.
Perhaps try $2.00 less per point and they pay 2005 maintenance. Are all 2005 points there? Any from 2004? Or offer the price asked BUT seller pays closing costs and maintenance....that would probalby be your biggest savings and in the seller's mind he could say "well I am getting a full price offer'
You CAN write any kind of offer...there are no rules except good sense and manners.
Good Luck
