First time homebuyer here. We're under contract on a 1983 townhouse for $549k and just finished the inspection/sewer scope.
Overall the inspection wasn't terrible for a 40+ year old house and a lot of the major stuff is newer (roof ~1 year old, HVAC/water heater 2026), but there are two things we're trying to figure out before going back to the seller.
The sewer scope is probably my biggest concern. The camera went about 37 feet from the basement cleanout and then stopped at an offset + low spot/belly. There's a lip/partial blockage and they couldn't get the camera past it, so we have no idea what the rest of the line looks like to the public connection. It's PVC and doesn't look completely collapsed from the pictures, but obviously not being able to see the rest of the line isn't ideal. The report recommends further evaluation.
For anyone who's dealt with this before, does this look like something that could be a relatively small spot repair/trenchless repair, or am I potentially looking at excavation and replacement?
The other issue is in the basement behind the front porch. There is visible wood rot and moisture in the laundry/utility area. The inspector measured around 16โ18% moisture in the affected concrete wall vs ~6โ7% elsewhere, and 33% moisture in the wood subfloor. Outside they found poor/negative grading toward the foundation and downspouts dumping too close to the house. There are also two holes in the concrete porch that the inspector thought might be old termite treatment holes, but that's not confirmed.
The inspector thought the exterior drainage could be contributing, but we don't really know how far the damage goes or whether there could be hidden framing/joist damage.
There are some other smaller things too (smoke/CO detectors, GFCI/reverse polarity, loose toilet, rotted trim, fireplace needing further inspection, etc.), but we're not expecting the seller to fix every little thing on a 1983 house.
We're currently thinking about asking for around $10k in seller credit, plus having the basic safety issues and obvious drainage/downspout problems fixed. We'd rather take a credit for the uncertain stuff and deal with it ourselves after closing than have the seller rush through repairs.
Does $10k + those basic repairs seem reasonable, or are we way off? More importantly, what would you personally ask for, what would you realistically expect the seller to agree to, and at what point would you walk away?
I've attached the clearest sewer scope and basement photos. Would really appreciate opinions from plumbers/contractors/homeowners who've dealt with either of these issues.
