Yes agree with the photos and date stamp them... that was one of the new guidelines for us clerks and I forgot to do it today! Doesn't matter though the report is dated today and visit attended by tenant! phew!
Get the carpet and oven cleaned professionally and keep the receipts.
If you can't afford to get the oven cleaners in, Oven Pride is the best thing since sliced bread. Costs about £5.00 Make sure all burnt on marks are off, photograph the inside with the flash on to see what will show up.
Make sure you don't miss the backs of doors for dust. skirting boards for same, door have both sides, and so do door frames, we look at everything. (yes I AM cross eyed at the end of the day!)
Washing machine: powder drawer, one of the favourites to pick up on is the powder compartment and the rubber seal. Before you move out, pour bleach into the powder compartment and leave to soak over night. The next morning put the machine on the hottest wash you have, and it will ensure your drum, the rubber seal and the powder compartment should be sparkling. Good time to stick your white towels in for a good boil wash!
Extractor hood, change the filter and make sure it's not sticky. make sure all bulbs are working. Cillit Bang is great for this one!
Clean all cabinets, wipe them out to make sure there is no debris.
Fridge - same
Freezer defrost and make sure it's clean, no stray peas
Windows - cleaned inside and out.
Bathroom/Sinks - Make sure all limescale is removed from bath, basin and drainages/taps - viakal is good or cillit bang apparently. Jif Spray mousse is AWESOME in the bathroom, spray it on tiles, bath, taps, shower risers, leave it for 15m and rinse off. To restore your tiles to pristine, give the tiles a bit of a scrub with a scouring sponge while the product is still on and dry the tiles after rinsing them off.
Don't forget the underside of the wash basin and the loo. Don't forget the WC seat and lid either.
Shed/Garage - make sure they are swept out and as free of cobwebs as poss.
Make sure all bulbs are tested and working
The only other suggestion I could venture is that you could ask their handyman (seeing as he hates her) if he could go round with you to make sure that there is nothing untoward with the property and write you an email to that effect.
When you have finished, you want to be able to say, could someone move in here after me and not know I had been here?
Did I miss anything?
