Submitted offer on a home and found mold during the inspection

[Chelsea Jean-Mary]

I recently submitted an offer on a lovely 3/3 condo a little bit outside of DC. The place is in my price range. However, I had the home inspection last week and we found a number of issues. A few of them being that the furnace would need to be replaced and there was mold in the furnace and exterior utility closet.

The listing agent informed my realtor that the seller will lower the price of the property in order for the deal to close. I'll have a little bit of cash saved up after the down payment but didn't necessarily want to drain it on fixes for the home to be move-in ready. I plan to get quotes to see how much this will cost. I've done facility maintenance work in the past for my first job and believe I'd be able to manage contractors but this wasn't a desired choice. I'm not sure if there are things I should consider if I decide to move forward with the purchase and getting this work fixed myself by hiring. My real question is: when does it make sense to walk away?

(I'm a first-time homeowner by the way.)
