Five Day Notices For Property Managers

Although it is an unpleasant task to evict non-paying tenants, it is necessary. If tenants are not paying rent, or are constantly struggling to pay rent on time, you have the right to remove these tenants and find new tenants who will respect their lease agreement and pay rent in a timely manner, with no difficulties or issues.

If you’re looking to remove tenants from your property, one common and effective method is through the use of a five day eviction notice.

The rates of ONQPI vary depending on the needs of your firm. Our services are tailored to meet the specific requirements that you seek when you hire us for service of process. The rates for service of process include mileage.
