3 family built in 1750, deal falling through?

[Jen Starr]

I requested work be done on a home I have an offer on based on the inspection. All of the work requested is structural. The property was built in 1750 and stone walls in the basement need reappointing (they're falling down), rotted wood beams need support, rotting floors, damage ceilings, majority of the outlets are ungrounded, etc. Estimates from a contractor, a mason, and an electrician came in at ~23k (pretty sure it will be more). The owners are investors/contractors who bought in 2007 for 195k and didn't do much it seems. The property was listed for 459 and they accepted 430. If I had known it needed 12k in electrical updates, etc I would never have offered 430. There is a lot more than structural/electrical work that the property needs like appliances, many cosmetics and two furnaces are ~10 yrs old. The property could bring in 4300-5000 gross rent (500-600 per room is market) so the value is there but when I add up the 25% down, cosmetics updates, appliances, furnaces, and *basic structural work totaling at least 25k* I lose interest. Initially the sellers agent implied they would be willing to do the work (the agent is the owners daughter and he's apparently a big contractor). Now they're saying we'll give you a 10k credit. I guess I feel like, well...never mind then. Its no longer a good deal and I'm getting a negligent owner vibe which makes me think they'll be more surprises along the way. Am I wrong for thinking the structural stuff and electrical stuff that came up on the inspection should be addressed? If this was a 250k property I'd expect this nonsense and assume it was my nonsense to fix but this is on the higher end of cost for a multifamily in this area. Super discouraged. I was hoping this would be my first multi 👎
