Re which way the property is facing- you can figure it out from a map if you have one to hand and can orient from the road- or carry a small compass on a keyring or something!
If the agents are hurrying you it is a sign that they are likely to be rubbish agents, so a red flag in itself.
My trick was to have my checklist on a clipboard, and make a point of checking everything. The clipboard keeps the agents in check a bit, I think it intimidates them to know that you are keeping track. I'd also sketch a floor plan on the back of the sheet, with orientation, so I could remember which property was which later (I'd see 10 in one day and take one by closing time…) Make a note of any wild claims they make so that you can dispute them at leisure later, if needs be.
Crucial checklist points were things like-
signs of mould
signs of pests
signs of damp
signs of damage to windows or roof
street lighting
proper mortice lock on front door
window locks
mobile signal?
Gas cooker/central heating?
For every key room I had
condition of decor and flooring
condition of fitted furniture
sufficient plug sockets?
Lighting (natural/artificial)
Questions to ask were:
council tax band? (they never know though!)
Who is the landlord and what are their circumstances (eg- bloke who used to live here and has one other place, giant company, person who is travelling and will come back)
Nearest shops?
Nearest public transport?
Anything that had ever pissed me or any of my household off was on there!
We'd even measure the front door and stairs to check our furniture could get in the door.
You can also ask to nip to the loo, which lets you check the plumbing, or to charge your phone whilst you look round, which lets you check a crucial socket.
