Do you own rental properties? If so, you are learning the importance of having your rents collected as quickly as possible.
The typical rental contract allows for a grace period of 3 to 7 days after the first. For example, if the rent is $700 and due on the first, the contract may allow for a 5 day grace period before the rents are due. Typically a late fee is attached to anything that is paid after this grace period.
Why not try this? Set the rent at $800 and give a $100 discount for paying on or before the first. Have late fees beging accumulating on the second.
You are still going to get your $700. You will be getting it on the first and not the fifth to the seventh. Your cash flow position will be strengthened.
Good luck and happy investing.
