I'm quite open, we where looking to buy a doer up anyway.
I wont live in the rough end of our town, so any house their is off instantly.
I instantly striked any house off from viewing that from photos clearly had an indoor free range rabbits. Rabbits are not house trained (I don't care what any rabbit owner says they just because they hit the litter tray occasionally does not make it so) and the damage and smell from rabbits can be horrendous (smaller caged animals like hamsters, rats, chinchillas etc... dont bother me). Only 2 or 3 house in 2 years fell under this rule though.
I wont bother going to see a house that clearly insanely hoarded, no point viewing if you cannot actually SEE any of the house (clutter does not bother me, if you live their I expect to see your stuff but when every inch is covered so you cant even see the walls nope). Once again only 2 houses fell under that rule too.
One of the free range rabbit houses also was blatantly FILTHY (like an inch thick grime on everything) from the photos which I noticed before noticing the rabbits and instantly thought 'ewww'. I don't expect wildly clean as we looked at lots of dated doer ups but there a difference from 40-50 years of wear and tear and actual feces and grease soaked into everything. Even without the rabbits I would have crossed it off for that.
I also won't go see a house listed as a '4 bed' if the 4th bedroom is actually the dining room. I need a 4 bed and you are clearly an average 3 bed, 2 reception room house and lying doesn't change that.
Hate open plan and clearly flipped houses too, never my taste and impractical but if I can re-close up the open plan with a stud wall I might still go look but not if they have put huge kitchen through it (or something else harder/expensive to move).
Other than that if it meets my requirements I would go have a look.
I did view one house that had no photos. It was on very cheap for being a good street and just a few houses from where I lived so no hassle to pop in. I quickly learned WHY it had no photos though. It was basically all in one hoarded, damp, smelly indoor pets, virtually derelict (water running down walls, mold everywhere) and stunk to high heaven of raw sewage (apparently the drain under the house had collapsed pulling it away from the adjoining neighbor hense the leaks, cracks, damp and smell).
Should have been a health hazard, more shocking is a whole family where living in it. The only house I have ever seen where I thought demolision is the only job for this. A flipper bought it, 'facelifted' it in record time (no where near enough time to do the structural work needed, just tape over the cracks, air it out and a lick of paint job) and whacked it up for a crazy amount of money... and it has not sold.
