Even then, I've caught people in compromising situations.You should also let the tenant know that if they refuse to let you change the filter, they can be held liable for any repairs resulting from a dirty filter and that it may be grounds for termination.Your lease should clearly stipulate your right to enter and perform maintenance as well as the Tenant's liability if they fail to allow regular maintenance.

@Benjamin Couchnah man. been married and divorced so yea i don't have the same trust that others in here might. i probably set myself back 7 years by putting that persons goals before mine and wound up left holding the bag anywaymarried or not never, i mean never, do anything remotely close to putting yourself in a compromising financial position behind a relationship. that person can leave at any moment there's absolutely nothing stopping them.

See if you can determine some compromise and offer a credit towards the new unit.

They're here on a study Visa and don't want to anything that could compromise that.

Some designers are not willing to compromise their artistic design choices in order to compensate for your budget.

Remove the late fee as a one-time forgiveness.I am leaning towards option 3 as they have been good renters overall, but I've read and listened enough to know that I do not want to compromise my lease/future payments.

:D Using bleach to get rid of mold is a lot more dangerous to those using it than remediation methods that actually remove the mold (not just kill it).Here is what the EPA says:"The purpose of mold remediation is to remove the mold to prevent human exposure and damage to building materials and furnishings....The use of a biocide, such as chlorine bleach, is not recommended as a routine practice during mold remediation, although there may be instances where professional judgment may indicate its use (for example, when immune-compromised individuals are present)."

If you want to try to make the tenant happy, you could always try to work out some sort of compromise - like offering to split the cost. 

Is there anything you can do to increase that (without compromising safety)?
