The last thing you want when you take possession of your new home is to find it in total disarray. Therefore, you should always be certain to make it clear in your offer that certain standards are required and must be met prior to you taking possession of the property - or  you will find that you may be unable to do or say anything about it afterwards. Make your conditions known first!

Some requirements you may want to include in your offer are -

All of the appliances must work
The roof does not leak - anywhere!
Any broken or cracked windows must be repaired
Plumbing does not leak and is in good working order
Any additional debris or garbage must be cleared away

Be certain to also specify -

Which fixtures stay - (Ceiling fans, Chandeliers, Draperies, etc..)
