I would get a Realtor to look at it and appraise it for you.
It might be worth much more than you think.
$80-$90k doesn't buy much these days.
A house on our street (in need of serious repair) just sold for $180k, which is about $100k more than i would've paid for it.
It looks like the buyer is making the repairs and intends to flip it.
I'll bet that it goes back on the market for $240k or more.
next door house similar sold for 85K is small town, etc. but yah, agree 80K does not buy much. If up to my brother it would sell for 75K tops he said. I am shooting for 90K with furnishings inside what we do not want. 2 auctioneers said 2 years ago before pandemic they could get 85K for house and 10K for furnishings if went thru their auction. Is only 1100 sq. ft, and 2 bedroom 1 bath but structure is pretty good foundation with oversized 2 car garage attached worth 25K of that 85K.
am sure she, or new buyer, will put new windows, carpet, linoleum, new water heater, and flip it for 130K or so making 20 grand profit.
Of course the only thing that I have to go by is how crazy the market has become around here.
I'm seeing houses sell for ridiculous amounts of money and in record time.
There are multiple places on the internet where you can find what comparable homes are selling for in your area.
Just keep in mind that you can always reduce the price but you can't go up later.
If I were in your shoes, unless I needed a super quick sell, I'd shoot for the moon.
Advertise it on Facebook Market Place and Craigslist ask $125-$140k, if you don't get any bites drop it down a bit.
The example of the house on my street, my estimate of the value would've been $80k tops.
The seller asked $160K and got $180k.
Apparently, it has become very common for people to bid above the asking price.
This is the house that I'm referencing:

3BR, 1 Bath 900 sq feet.
