Brian Karlow Adding antifreeze to your heating system is definitely something you could do to help prevent a freezing problem.

I think it heats 100 gallons in 6 minutes or something.

After you get that information, use it to calculate your return on that investment.From a quality of life stand point, forcing 2 families to share the same AC/heat is a scene set for disaster. 

The listing agent even noted that the heat is turned on and working. 

Would you hire an architect to do plans and follow that or would you do major systems first (HVAC, ZONE HEATING, ELECTRIC, PLUMBING, ROOF, ETC).Bottomline, which would you make sure was done 1st, 2nd, 3rd?

Should be pretty simple on your side - just cutting a check, but the broker will probably put some heat on the agent if the 2 of them didn't have a conversation about this prior to it all going down.  

DO you have heating?

Maybe it is because the market has heated up and people are simply paying too much.

During this time there has been partially functioning heat which the tenant supplemented with space heaters.

If you're looking to meet other investors heat to Pittsburgh REIA, the subgroups in your area, ACRE, or any of the others.
