Any suggestions or Insights to tenants who are very "Particular"

[Jack J. Nowotarski]

Hello everyone,

I have a single family rental in a A quality neighborhood that has been nothing but fantastic for the past year and a half. The original tenant was a Godsend and honestly just paid us to use the 1350ft^2 house as a storage unit for a year and a half, unfortunately she has moved on. The home has very little wear and tear on it as most of the property had recently been updated. We recently signed our new set of tenants to the property for a 12 month lease, a young couple very well put together and qualified. On paper they are the ideal candidate and made it through our screening, background and income verification with no problems what so ever. Prior to moving in I made minor repairs, and had a cleaning crew come through and perform a deep clean prior to the new tenant moving in.

We as landlords provide a tenant move in packet, which has a move in check list which the new tenant. We have sections for each room and subsections for floor, walls, counters, ceiling fans, etc... rating them on a 1 - 5 scale, with 1 being horrible and 5 being perfect.

The issue is: The tenant rated almost everything throughout the entire home as a 1, literally everything had issues. Ex. the wood-burning fire place was rated a 1 due to residual ash and rusting iron firewood holder. The white towel/linen racks in the linen closest had a visual yellow stain on one of the lower racks. They rated the hardwood floors throughout the house as a 1 due to minor scratches from furniture and habitation traffic. Long story short they are very particular and had verbally stated the house was in a disgusting condition when moving in.
Now they seem like upstanding individuals but are very particular about their living conditions, but what I am worried about is if they trash the house and when we go through the move out check list, they claim that it was like this originally since when they moved in everything was disgusting, when it clearly wasn't. 
Also we had taken pictures before the tenants moved in but nothing super in depth just room shots.

Does anyone have any suggestions as to how to approach this, or any advice?

Cheers,
