This is a common occurrence in real estate; the listing agent often makes an assumption about the property's lendability without ever talking to a lender. In this case, the listing agent felt the stand alone gas heater (that wasn't currently working) in the main floor living room wasn't enough to qualify as a "heat source". (Most all lenders require the property have a heat source.)
Over the course of the transaction, we were able to get an HVAC contractor to the property and have the unit tuned up (they found a bird's nest in it, which is why it wasn't working!) We had the gas turned on just in time for the appraiser to come out and inspect the property.
The appraiser had no problem with the unit, and considered it a heat source for the loan. Lasse was able to purchase a centrally located property, without dealing with a huge amount of competition from other buyers, because the listing agent improperly listed the house.
Just another example of a happy client! Let me know if you'd like to join the growing ranks of my happy clients; I'd love to help. firstname.lastname@example.org
