Since there still seems to be some confusion about how long it take for houses to fall I will provide a more detailed explanation.
First case is where your account is inactive for 90 days then becomes condemned.
Second case is where you trade an existing house or place a new house and the first house becomes condemned.
As stated in the Producer Letter houses will fall within 5 days. There are 6 states that the house will transition to within the 5 days. There is no defined time that a house will be in each state.
Decay Stages:
1. Like New
2. Slightly Worn
3. Somewhat Worn
4. Fairly Worn
5. Greatly Worn
6. In Danger Of Collapsing
So an example:
Day 1: Like New-> Slightly Worn
Day 2: Slightly Worn
Day 3: Slightly Worn -> Fairly Worn
Day 4: Fairly Worn -> Greatly Worn
Day 5: Greatly Worn-> In Danger Of Collapsing -> Drop
Another example:
Day 1: Like New-> Slightly Worn
Day 2: Slightly Worn -> Fairly Worn
Day 3: Fairly Worn -> Greatly Worn
Day 4: Greatly Worn
Day 5: Greatly Worn ->In Danger Of Collapsing -> Drop
