HVAC Concerns for New Purchase

[Nate Doh]

Hi, I am in the process of buying a new home. But, it looks like the HVAC system is very old and will need to be replaced within the next year or so. It would cost me $7,000 out of pocket to replace it. I would ask the sellers for financial assistance for this repair, however, it appears that the sellers rejected the buyers that came before me because the previous buyers requested $6,000 for repairs. I want this house since it is in a good area, but is it worth purchasing if I know I will have to replace the HVAC system soon? Any advice would be appreciated, thank you.
